All work shall be done in a professional manner. When surveying is performed by someone other than the Department, the correct alignment and elevation of the water mains as shown on the approved drawings becomes the responsibil- i ty of the Applicant and Contractor. Approval of the staked alignment and elevations by the Department's Inspector does not relieve the Applicant and Contractor in any manner from the responsibility for field errors. Sufficient line and grade shall be staked to ensure continual work progress. Revised 07-92 2-12 2.10 PLACING SURVEY LINES When surveying is required, hubs and stakes shall be set on an offset line to mark the location of the centerline of the main. Centerline hubs and stakes may be used in addition to the offset hubs and stakes; however, they may not be set in place of the offset hubs and stakes. Normal practice is to set offset hubs and stakes five feet (5') to ten feet (10') off the center- line of the main. survey points shall be set a maximum distance of one hundred feet (100') apart. All valves, crosses, tees, horizontal and vertical bends, and fire hydrants shall be staked for location and grade. Points of curvature and points of tangency of curves, as well as points on the curve, shall be staked for location and grade. All stakes shall be flagged to increase their visibility. stakes shall be positioned so that the survey hub is between the stake and the main. The side of the stake facing the main shall be marked to show the point being referenced and the distance from the hub to the centerline of the main. The back side of the stake shall be stationed. Grade stakes shall be set at each hub and shall state the vertical distance from the top of the hub to the top of the pipe. This vertical distance will be based on the fact that the distance from the official street elevation to the top of the pipe shall be as specified in Section 8.06 or as shown on the approved plans. The Applicant and the Contractor shall take reasonable steps to prevent alteration, displacement or removal of hubs and stakes. 2 . 11 INSPECTION Installation of all new facilities will be inspected and approved by the Department. The Department will ensure that the provisions of the approved plans and specifications are complied with, especially with regard to the quality of workmanship and materials. Problems which may require sound field judgment, in lieu of strict interpretation of the Specifications, shall be resolved by the Department and the contractor, and any resulting monetary differences shall be resolved between the Contractor and the Applicant. All work shall be performed in accordance with accepted workmanship practices and these Engineering Standards. Any work not accepted by the Department shall be done over until compliance with these Engineering Standards is achieved. Revised 07-92 2-13 All appropriate permits shall be on the jobsite and shall be checked by the Inspector before starting construction. Orders given by the Department relating to quality of materials and workmanship shall be complied with promptly by the Contractor. All materials used shall be subject to the inspection and approval of the Department at all times, and shall not be used before being inspected and approved by the Inspector. The Department has the right to perform any testing deemed necessary to ensure compliance of the materials with the Materials Specifications. Failure or neglect on the part of the Department to condemn or reject work or materials not in accordance with the Materials Specifications, shall not be construed to imply their acceptance should their inferiority become evident at any time. Materials rejected by the Department shall be immediately removed from the jobsite. 2.1.2 CONTRACTORS AND APPLICANTS Contractors performing all work for main extensions shall be competent, licensed firms with adequate manpower and equipment to accomplish the work in accordance with the approved plans and specifications. A representative of the Applicant and the Contractor shall be present at the jobsite whenever work is being conducted by sub-contractors. Contractors and applicants shall meet the following requirements with regard to qualification, financing, and guarantees: A. Qualification: Contractors desiring to install main extensions or other water facilities for the Department on behalf of an applicant shall be prequalified. "Request for Contractor Prequalification" forms (see Exhibit 2 of the Appendix) may be obtained from, and returned to the Department at least thirty (30) days prior to the date the Contractor anticipates beginning installation of the Main Extensions. Following evaluation of the completed form, written notice of acceptance or denial will be transmitted to the Contractor. Prequalification is subject to yearly application and renewal. B. Letter of Credit: Applicants shall provide the Department with an acceptable irrevocable Letter of credit, or other suitable financial guarantee from a financial institution authorized to do and doing business in the State of California, valid until the Main Extension is accepted by the Department.

The Department· s determination of this point shall be final. 2.14 SPECIAL CONDITIONS All conditions involving another agency, such as cross- ing a railroad or a highway, shall be satisfied. All designs, drawings, and calculations submitted to said agency shall also be submitted to the Department for approval. Should a conflict in the plans and specifications occur between the Department and the other agency, the plans and specifications yielding an acceptable product, as determined jointly by the Department and the other agency, shall prevail. Revised 07-92 2.15 EXCEPTIONS UNDER CHAPTER 2 The Department reserves the right to and/or install mains when it is in the best interest of Department. This determination is solely at the discretion of the Engineer. The Applicant shall pay all design and installation costs for extending mains whether installed by its own contractor or by the Department. Revised 07-92 CHAPTER 3 SYSTEM DESIGN 3.01 GENERAL The purpose of this chapter is to provide general information on the design of a water distribution system acceptable to the Department. The Department's Distribution System is designed to deliver water to its customers in sufficient· volumes and without excessive headloss. Specific design and layout criteria for Distribution Mains, service installations, Supply Mains, and Trunk Lines are covered in Chapters 2, 5, 6, 9, and 10 respectively. 3.02 SIZING OF DISTRIBUTION HAINS The Department designs its distribution facilities to obtain the lowest cost over their expected life. This may not necessarily result in the lowest initial cost when long-term operation and maintenance costs are considered. This policy f however I results in a water supply system that yields optimum quality service at the lowest total cost to the consumer. All mains will be sized by the Department large enough to provide the consumer a minimum of forty-three pounds-per-square-inch (43 psi) residual pressure at the building pad at peak-hour demand for domestic needs and twenty-five pounds-per-square-inch (25 psi) residual pressure at the building pad at peak-hour demand plus private fire demand (established by the local fire department) for fire services. Mains will also be sized to meet the public fire supply requirements of the local fire department. The Main Extension shall be capable of provid- ing a minimum residual pressure of twenty pounds-per-square-inch (20 psi) at the most critical fire hydrant with peak-hour demand plus fire demand established by the local fire department. Generally I Distribution Mains are sized for a headloss of five feet per thousand feet (5 '/1000') of main at peak-hour flows. The Department reserves the right to size mains to provide service for future needs. All new Distribution Mains shall be of the standard sizes used by the Department. Standard sizes are: six-inch (6") I eight- inch (8") I and twel ve- inch (12") mains. Four- inch (4") main may be used in short cul-de-sacs not requiring fire hydrants or fire services larger than two inches (2") in size. The sizing of Distribution Mains normally follows a standardized grid based upon careful consideration and analysis of results of distribution system studies utilizing network simulation. Revised 07-92 3-2 In residential districts zoned R-1, mains are usually six inches (6") in diameter in a grid system and four inches (4") in diameter in short cul-de-sacs. In residential districts zoned R-3, system is usually comprised of a mixed pattern and eight-inch (8") grid. the distribution of six-inch (6") In areas zoned R-4, Commercial, and Industrial, a grid of eight-inch (8") mains and sometimes twelve-inch (12") mains is generally adequate to meet domestic and fire protection needs. Looping is done whenever possible in conjunction with the Main Extension to maintain water quality and improve reliability of the system. The present sizing of the grid system has the benefit of utilizing the system as an integral part of the overall supply system to distribute water without excessive headloss. The Department will analyze grid systems for developing areas to determine their adequacy. 3.03 OPERATING PRESSURES WITHIN THE DISTRIBUTION SYSTEM Pressures within the Distribution system shall be a minimum of forty-three pounds-per-square-inch (43 psi) at the building pad during peak-hour demand, whenever possible. At building site elevations where the minimum pressure is under forty-five pounds-per-square-inch (45 psi), the Contractor is required to install oversized plumbing in accordance with the Los Angeles City Plumbing Code. An Elevation Agreement shall be executed by the Applicant and the Department for the portion of any lot having a minimum pressure of less than thirty-five pounds-per-square-inch (35 psi). Every effort shall be expended to grade the lots within subdivisions to enable the Distribution System to provide a minimum pressure of thirty-five pounds-per-square-inch (35 psi). Future growth and main deterio- ration result in future consumer problems if water pressure is not provided at adequate levels. Domestic pressure regulators are required in accordance with the Los Angeles city Plumbing Code Where the maximum static pressure exceeds eighty pounds-per-square-inch (80 psi) at the building site elevation. 3.04 PRESSURE REGULATING STATIONS Pressure regulating stations are used within the Distribution system to control pressures between service zones. When main extension plans are submitted for review, the need for a pressure regulating station will be determined by the Department based on existing pressure zones and the existing Distribution System. The Department will make all pressure set- tings and field adjustments on pressure regulating stations within the Distribution System. Revised 07-92 3-3 In certain situations, the Department -will require monitoring of the station's rate of flow and upstream and down- stream water pressures via electronic telemetry. The equipment used shall be of the manufacture and type specified or approved by the Department. See section 3.07 of these Standards. 3.05 STORAGE FACILITIES A. General: Water storage facilities will be allowed for storing water within the Distribution System only where specifically authorized by the Department. The type, size, and location of storage facilities to be used shall be determined by the Department. It is the policy of the Department to require the Applicant to design and construct water storage tanks if the tank is required for the Applicant's development. The Department, however, reserves the right to design and/or construct (with its contractor) tanks when it is in the best interest of the Department. All plans and specifications submitted to the Department for review and approval of water storage facilities shall be prepared by a Professional Engineer registered by the State of California. The Applicant is encouraged to contact the Department at least three years in advance of when a storage facility may be needed so adequate time is available for environmental documentation, engineering, and construction. B. Environmental Documentation: Environmental documentation for tanks should be dealt with at an early date so that the cumUlative impacts of deve- lopment can be considered. Normally, this means that special water supply facilities, such as tanks, should be discussed in the Subdivision Environmental Impact Report. Performing environmental documentation on a tank as a separate project may result in significant delays to the Applicant. C. Engineering and Geology: It is extremely critical that no grading occur on a potential tank site prior to obtaining engineering and geology approval of the grading plan. The Department requires that its tanks be constructed on bedrock when possible. The Department will establish the high water elevation and tank dimensions after review of preliminary development plans. D. General Design Criteria: Specific design criteria for the tank will be established after consideration of all Revised 07-92 3-4 site conditions and current development plans for the area. The following general design criteria will apply: 1. The structure shall conform to the requirements of the Los Angeles City Building Code except as modified by the Department to provide an increased factor of safety. 2. All soils and geology reports shall be approved by the Los Angeles City Department of Building and Safety and the Department. 3. All footings shall be founded on bedrock. 4. Design of walls shall include dynamic earth pressure. 5. Walls shall be designed to withstand possible surcharge due to an earthquake. 6.

Revised 07-9.2 3-5 17. Adequate landscaping shall be provided for the area around the tank, including all slopes. 18. The Design Engineer shall obtain all required clearances, approvals, and permits. 3.06 PUMPING FACILITIES A. General: Pumping facilities may be needed to provide adequate water pressure in the Distribution System. The type, size, and location of all pumping stations within the Distribution System shall be specifically authorized by the Department. The Department will prohibit the installation of pumping facilities where, in its opinion, such installations would be injurious to the operation, or future operation, of the Department's Distribution System. It is the policy of the Department to require the Applicant to design and construct pumping stations if the pumping station is required for the Applicant's development. The Department, however, reserves the right to design and/or construct (with its contractor) pumping stations when it is in the best interest of the Department. All plans and specifications submitted to the Department for review and approval of pumping stations shall be prepared by a Professional Engineer registered by the State of California. B. Environmental Documentation: Environmental docu- mentation for pumping stations should be dealt with at an early date so that the cumulative impacts of development can be considered. Normally, this means that special water supply facilities, such as pumping stations, should be discussed in the Subdivision Environmental Impact Report. Performing environmental documentation on a pumping station as a separate project may result in significant delays to the Applicant. C. Engineering and Geology: It is extremely critical that no grading occur on a potential pumping station site prior to obtaining engineering and geology approval of the grading plan. The Department requires that its pumping stations be constructed on bedrock when possible. The Department will establish the exact location after review of preliminary development plans. Revised 07-92 3-6 D. General Design Criteria: Specific design criteria for the pumping station will be established after consideration of all site conditions and current development plans for the area. The following general design criteria will apply: 1. The building shall conform to the requirements of the Los Angeles City Building Code except as modified by the Department to provide increased resistance to damage due to seismic loads. 2. All soils and geology reports shall be approved by the Los Angeles City Department of Building and safety and the Department. 3. All footings shall be founded on bedrock. 4. All design criteria shall be placed on the drawings and approved by the Department. 5. The building shall be aboveground and be located so that the pumps will be supplied by gravity water. 6. The architectural style of the pumping station shall be compatible with or similar to the style of the neighboring residences. 7. Adequate parking and access control shall be provided for the facility. 8. Noise within the pumping station shall be within acceptable levels. 9.

Adequate landscaping shall be provided for the area around the building, including all slopes. Revised 07-92 3-7 15. An adequate building floor drain shall be provided. 16. The Design Engineer shall obtain all required clearances, approvals, and permits. 3.07 TELEMETRY AND CONTROL SYSTEMS Telemetry and/or data acquisition and control systems installed for use by the Department to collect data, monitor, control remotely and coordinate the operations of its water sys- tem, or the operations between a distributor's water system and the Department's system, shall be designed, installed and main- tained by the Department unless other specific arrangements are made during the design phase of trunk line, pressure regulating stations, storage facilities, or pumping facilities. 3.08 CONNECTIONS TO THE EXISTING DISTRIBUTION SYSTEM connections to Distribution Mains or Supply Mains will generally be made by the contractor unless the Department deter- mines it is in its best interest to have the Department make the connection. See Section 8.26 of these Standards. All connections to Trunk Lines owned or controlled by the Department will be made by the Department. The Department will provide and install all fabricated pipe, tapping sleeves, valves, etc., that are necessary to construct the connection. Revised 07-92 4.01 GENERAL CHAPTER 4 EASEMENTS AND USE OF DEPARTMENT PROPERTY The following procedures have been developed to process easements as quickly as possible through the Department.

Width Requirements for Main Installation: All mains shall be installed in the paved roadway section of dedicated streets having alignment and grade approved by the City Engineer. When the Department determines it is not feasible for an installation to be made in a dedicated street, the installation shall be made in an easement. The conditions under which such an exception will be allowed will be determined for each individual case, and only easements which conform to the terms of the Department's Standard Dedication Certificate will be accepted (see Exhibits 3 and 4 of the Appendix). The minimum width of exclusive easements accepted by the Department is twenty feet (20'). Nonexclusive easements will be accepted only over full-width private streets that conform to the City Engineer's standards for public streets. Installations may be made in streets or easements of other widths only when author- ized by the Department. B. Dedicated Streets: Mains shall be installed in dedicated public streets of such grade, alignment, curvature, and other characteristics as to permit them to be laid and maintained in the normal and usual manner. Main alignment shall be parallel to property lines. Normal practice is to lay the main no closer than and preferably a distance of six feet (6') from the curb on the south or the west side of the street except in hillside areas where they are located on the uphill side of the street. The main shall be installed no closer than four feet (4'), centerline to centerline from adjacent substructures. In no case shall there be less than two feet (2') clear between the trench line of the main and the trench lines of adjacent substructures. Special conditions detailed in section 8.18 apply to mains installed adjacent to or crossing sanitary sewers. Revised 07-92 5-2 C. Easements: Mains installed in easements shall conform to the terms of the corresponding Department Standard Dedication Certificate including proper surface drainage (see Exhibits 3 and 4 of the Appendix). D. Alleys: New installations of mains strictly prohibited. Replacement of allowed under special circumstances. in alleys are mains may be E. Fire Hydrants: All fire hydrants shall be installed within dedicated streets. When the Department determines it is not feasible for a hydrant to be installed in this manner, it shall be installed in an easement contiguous to said dedication. The fire hydrant easement shall be acquired on the corresponding Department Standard Dedication Certificate (Exhibits 3 and 4 of the Appendix) and have a minimum width and length of five feet (5') for standard installations. Fire hydrants shall be installed at general locations determined by the local fire department, and modified by the following field conditions: 1. Normally on the short lateral side of the street. 2. On the uphill side of the street in hillside areas. 3. No closer than four feet (4') clear of adjacent substructures or aboveground facilities. 4. At lot lines. 5. No closer than and preferably at clear of adjacent driveways wheelchair ramps. five feet (5 ' ) and sidewalk 6. For curbs having a radius of twenty feet (20') or larger, no closer than and preferably at five feet (5') from the B.C. of the curb, not in the curb radius, and twenty-two inches (22 to) from the curb face to the center of the fire hydrant. 7. For curbs having a radius smaller than twenty feet (20'), no closer than and preferably at ten feet (10') from the B.C. of the curb, not in the curb radius, and twenty-two inches (22") from the curb face to the center of the fire hydrant. F. Line Valves: Line valves are required approximately every six hundred feet (600') to twelve hundred feet (1200') in all twelve-inch (12") and smaller Distribution Mains receiving water from the Department. Revised 07-92 5-3 Where blocks exceed six hundred feet (600') in length, or if two (2) or more hydrants are connected to the same main, additional line valves may be' required in the middle of the block. For a succession of short blocks perpendicular to the direction of major feed and without residential services, several intersections may have the valve omitted in that direction but should retain the six hundred foot (600 ') to twelve hundred foot (1200') interval requirement. Line valves are generally installed adjacent to the fitting connecting intersecting mains. Street intersections carrying heavy traffic, or containing major Distribution Mains in both streets may require four (4) valves, one at or near each extended property line and adjacent to fire hydrants, if possible. 5.03 AND TESTING The materials and construction methods specified herein are based upon lowest life cycle cost, not upon lowest initial costs. The Department considers long-term operation and mainte- nance costs to procure a water supply system that yields optimum quality service at the lowest total cost to the consumer. Detailed technical specifications (or a reference to industry specifications) for purchase or approval of materials are included in the Materials Specifications Section of these Standards. All materials shall conform to the Materials specifications and to all limitations on acceptable makes and styles. Steel pipe not purchased from the Department is subject to inspection and testing in accordance with DWP specification W- 302, at Applicant's expense. The Department shall be notified at least four (4) weeks prior to start of manufacturing. All materials furnished shall be new, undamaged, and clearly marked to allow identification during installation. Everything necessary to complete all installations in accordance with the Engineering standards of the Department shall be furnished and installed whether shown on approved drawings or not, and all installations shall be completed as fully operable functioning parts of the Department's Water System. Where mains are extended by the applicant, it shall be the applicant's responsibility to provide all materials necessary for the installation. However I certain materials not readily available from waterworks suppliers may be purchased from the Department. Acceptance of materials, or the waiving of inspection thereof, shall in no way relieve the Applicant of the responsibility for furnishing materials meeting the requirements of the Materials Specifications. Revised 07-92 5-4 New water industry products or materials will be tested by the Department if the Engineer feels the product or material has some merit. The Department will establish the criteria for testing and evaluating the product. Adequate lead time shall be allowed for testing of previously unapproved materials so as to not delay the project. The Department reserves the right to accept or reject any product or material regardless of the test results. 5.04 SIZING AND SELECTION OF PIPE All mains will be sized by the Department in accordance with section 3.02. Pipe materials will be selected by the Department in accordance with the guidelines on Sheet 5 of the Standard Drawings. However, the Department reserves the right to deviate from those guidelines in specific circumstances. 5.05 PIPE FITTINGS A. Joints: Joints and fittings shall conform to applica- ble DWP and AWWA Specifications. Acceptable joint types for straight lengths of ductile iron and steel pipe are push-on and slip-joint welding, respectively. Mechanical joints for straight lengths of pipe will be allowed only when specifically approved by the Department. Lead joints may be required when installing special fittings. Flange joints are required when installing four-inch (4") and larger line valves in steel pipe, four-inch (4") and larger tapping sleeves, and other fittings. No other type of joint shall be used without the specific approval of the Department. Flanges and flanged fittings shall have a rating that meets the maximum static pressure at the location of installation. Care should be exercised to select flanges and flanged fittings that have matching drilling templates. As a rule of thumb, flanges and flanged fittings having a 200 PSI or smaller rating or class, match. Also, flanges and flanged fittings having a greater than 200 PSI rating or class, match. B. Closure Fittings: Mechanical couplings shall be of a gasketed, sleeve-type, with diameter to properly fit the pipe. Tolerance on pipe and coupling, together with proper bolt and gasket arrangements, shall be sufficient to ensure permanent watertight joints under Revised 07-92 5-5 all conditions. Where pipes of different outside diameter are connected together, or where pipe is connected to fittings of different materials, care shall be exercised to select the proper ring or adapter. C. Repair Fittings: Repair clamps, repair sleeves, joint clamps, and similar devices shall not be used to repair or join water mains. Pipe damaged during installation shall be removed and replaced. D. Miscellaneous Pipe Fittings: Adapters, plugs, end caps, bulkheads, slip sleeves, anchor boxes, lock-joint gaskets, yokes and rods, and other appurtenances shall be used where appropriate throughout the system, subject to the approval of the Department. The Department does not intend to unreasonably limit the installation of any type of fitting, joint, or proprietary device; however, the installation of any such fitting, not specifically approved by these standards, is subject to the approval of the Department. written request for approval of deviating items shall be made in advance through the Department. E. Tapping Sleeves: Tapping sleeves or clamps shall be used to tap existing water mains that are in service and under pressure without interrupting service. NO TAP SHALL BE MADE IN ANY EXISTING WATER MAIN W:ITHOUT WRITTEN CONSENT OF THE DEPARTMENT. Care shall be exercised to select sleeves and gaskets which are properly sized to fit the type and class of pipe to be tapped. Where four-inch (4") or larger tapping sleeves or clamps are used, a thrust block shall be formed and poured behind the sleeve to prevent possible damage to the main from pressure shocks which develop as valves are first opened. Most tapping sleeves four-inch (4") and larger currently used by the Department require rubber gaskets. Pouring of molten lead during installation may be required in some cases. F. Line Valves: Line valves shall be gate valves conform- ing to the Department Specifications. Line valves shall be the same size as the main and shall open to the left (counterclockwise). Line valves in ductile iron pipelines shall have push-on ends. Line valves in welded steel pipelines and valves used in conjunction with tapping sleeves shall have flange ends. six-inch (6") and larger line valves shall be fitted by the Contractor with a two-inch (2") by-pass valve in accordance with Sheets 17 and 18 of the Standard Drawings. Revised 07-92 5-6 G. Check Valves: A check valve permits flow in one direc- tion only, closing when the flow stops so that no flow reversal can occur. They are generally used in meter installations and at service zone boundar-ies to allow the lower service zone to provide supply to the higher service zones during emergencies. They are otherwise prohibited unless specifically approved by the Department. (See Sheets 21 and 22 of the Standard Drawings. ) 5.06 FIRE HYDRANTS Fire hydrant type and size is determined by the local fire department. Standard types of fire hydrants currently used by the Department are two and one-half-inch (2-1/2") single built-up, two and one-half-inch (2-1/2") by four-inch (4") dou- ble, and four-inch (4") by four-inch (4") double. The single type is used where the maximum static pressure is in excess of two hundred and ten pounds-per-square-inch (210 psi) and the two double types are used where the maximum static pressure is two hundred and ten pounds-per-square-inch (210 psi) or less. Fire hydrant installations shall have all joints within the lateral restrained. Push-on joints, cast mechanical couplings, and steel mechanical couplings shall be fitted with lock-j oint gaskets I yokes and rods, and anchor box assemblies I respectively. Ductile iron fire hydrant installations shall have the lateral, bury ell and mid-section encased in polyethylene material in accordance with section 5.07(A) and S.10(E). All steel mains shall have fire hydrant laterals of steel only. Ductile iron mains can have fire hydrant laterals of either ductile iron or steel. See Sheets 28A thru 33 of the Standard Drawings. 5.07 CORROSION MITIGATION For all main extensions, the Applicant shall provide to the Department after the curbs and gutters have been-installed, a soil resistivity survey of the main installation area performed by a Corrosion Specialist certified by the National Association of corrosion Engineers, or a corrosion Engineer registered by the State of California. The soil resistivity readings shall be taken at each intersection, cul-de-sac, 500 foot intervals, and both sides of obvious cut and fill areas. A. Polyethylene Encasement Material: Polyethylene tUbes shall be used on all cast iron or ductile iron pipe, fittings, rods, and appurtenances. Polyethylene mater- ial shall conform to the Materials specifications and shall be installed as shown on Sheet 11 of the standard Drawings. Revised 07-92 5-7 B. Cathodic Protection: All steel mains shall be placed under a galvanic cathodic protection system that is: 1. Designed in accordance with guidelines established in this Section. 2. Reviewed and approved by the Department. 3. Installed and tested as shown on Sheets 27A thru 27D of the Standard Drawings, by a Corrosion Engineer (someone under the direct supervision of, or by a Corrosion Specialist certified by the National Association of Corrosion Engineers, or a Corrosion Engineer registered by the State of California. Revised 07-92 Steel mains, including fire hydrant laterals and service laterals four-inch (4") and larger shall be electrically isolated from cast iron, ductile iron, concrete cylinder, and existing steel mains with Department-furnished pre-assembled insulating flanges. Test stations shall be located, in order of preference, adjacent to fire hydrants, adjacent to line valves, and adjacent to insulating flanges. Following is a table that lists insulating flange, anode, and test station requirements for various situations that may be encountered during design of a main extension involving steel pipe: 5-8 Pre-Ass'd Ins.

Revised 07-92 5-9 5.08 BLOW-OFFS Two- inch (2") blow-offs shall be required whenever a Distribution Main dead-ends unless a fire hydrant, which can serve as a blow-off, is provided at the same location. Two-inch (2") blow-offs shall be assembled as shown on Sheets 15 and 16 of the Standard Drawings. 5.09 STEEL PIPE STANDPIPES AND MAINTENANCE HOLES Steel pipe standpipes and maintenance holes shall be provided for access to four-inch (4") and larger check valves and other installations. See Sheets 21 and 22 of the Standards Drawings. 5.10 REINFORCEMENT OF OPENINGS IN WELDED STEEL PIPE Fittings used to divide or combine flows (i.e., tees, crosses) do not have as high a resistance to internal pressure as pipes of the same thickness. This is because a portion of the side wall of these fittings is removed to allow for the branching pipe. The strength of these fittings shall be investigated and reinforcement provided in accordance with Sections 13.3 thru 13.7 of AWWA MIl, "Steel Pipe - A Guide for Design and Installation", as last revised. 5 • 11 THRUST BLOCKS Concrete thrust blocks shall be sized for the test pressure of the main and the allowable soil bearing capacity. The test pressure is generally one and one-half times the maximum static pressure. For design purposes, a minimum of 200 psi shall be used for all main installations. Standard sizes and shapes of thrust blocks based on two hundred (200) psi water pressure and various types of soil are shown on Sheet 12 of the Standard Drawings. The thrust blocks shall be two thousand (2000) psi or greater compressive strength concrete conforming to the Materials Specifications. 5.12 LENGTH OF RESTRAINED PIPE Ductile iron fittings subjected to unbalanced hydrostatic forces and the adjacent sixty pipe (ten (10) lineal feet for horizontal shall be restrained with lock-joint gaskets mechanical couplings). Revised 07-92 (60) lineal feet of 11-1/4 degree bends) or yokes and rods (at 5-10 steel pipe shall be restrained throughout the entire length. Noninsulating mechanical couplings shall be fitted with anchor boxes and shall be electrically bonded in accordance with Sheet 14, and Sheets 27A and 27B of the Standard Drawings, respectively. 5.13 PROTECTIVE CONCRETE SLABS OVER PIPE Under unusual circumstances, it may be necessary to lay pipe at shallow depths. Concrete slabs shall be used over the pipe to protect it from traffic. The slabs shall be designed to support traffic loads without transmitting the impact, or load, to the pipe whenever the pipe cover is less than two feet (2'). Concrete slabs shall be installed only with the approval of the Department. 5.14 CASING PIPE Installation of mains through rights-of-way or ease- ments of others, such as highways, railroads, etc., may require encasement or thimbles. The type of casing materials and its properties will be specified by the agency granting permission to cross. The casing shall not come in contact with the pipe being encased. Such crossing shall also be subject to approval by the Department to avoid conflicts in requirements or standards between the Department and the persons or agency granting permission to cross. Revised 07-92 CHAPTER 6 SERVICE LATERALS AND METERS 6.01 GENERAL water is conveyed from mains to the plumbing of customer's premises by service laterals. In the context of these Standards, service laterals include all pipe, fittings, valves, and appurtenances up to the meter. All water pipe beyond the meter is controlled by the Los Angeles Plumbing Code. All new or replacement domestic and fire service laterals installed in areas being supplied with potable water from the Department shall conform to the following minimum standards which shall be binding regardless of the regulations of any other agency covering like installations. 6.02 OWNERSHIP AND MAINTENANCE . Rule 16 of the Rules Governing Water and Electric Service in the City of Los Angeles deals extensively with ownership, installation, and maintenance of service laterals and meters. These Engineering Standards are intended to be supplemental and subordinate to those rules and will be so construed in any conflicting situations. A. Ownership: The service lateral and meter through which a customer receives water service from the facilities of the Department are the sole property of the City under the control of the Department and installed at the expense of the Applicant. B. Maintenance: The Department will maintain the service lateral and meter except as set forth under the refer- enced rules. A customer shall provide and maintain reasonable access for Department representatives to all service laterals, meters, backflow prevention devices, or other facili- ties pertinent to water service installed on the customer's premises. C. Repair Services Available: The Department will main- tain and repair the service lateral and the meter. The customer has total responsibility for all repairs be- yond the meter. Revised 07-92 6-2 6.03 LAYOUT service laterals shall not be installed within a three-foot (3') horizontal distance of other utilities. The main to be tapped shall extend along the front lot line of the property to be served. In the case of corner lots, the property may be served from the side lot line. If service is requested for lots at the end of a cul-de-sac street, the main to be tapped shall not be more than fifty feet (50') from any property line in the cul-de-sac. 6.04 COMBINATION SERVICE LATERALS A property requiring a domestic service lateral and a fire service lateral is generally served from a single tap. The domestic service lateral is connected to the fire service lateral ahead of the fire service curb valve. No more than one domestic service connection shall be installed on a fire service lateral unless specifically approved by the Department. occasionally, services and fire hydrants are supplied from a single tap. 6.05 PUMPS Except where specifically authorized by the Department, the installation of pumps designed to increase water pressure in service laterals is prohibited. 6. 06 SERVICE TAPS A. On Existing Water Mains: Service taps (connections) on existing mains are generally made by the Department while the main is in service. The Contractor may be required to install four-inch (4") and larger services by connecting to the valve provided by the Department. In specific instances, the Department may allow service taps to be made by an approved contractor. - B. On New Water Mains: service taps on new mains installed by contract are made by the Contractor. Service connections shall be wet-tap. Wet-tap connections shall be made after testing and disinfection of the main installation. Refer to section 8.27 for other conditions which must be met prior to wet-tapping. Revised 07-92 6-3 C. Tapping: Adjacent taps shall be spaced - a minimum of two feet (2'). In tapping water mains, it may be necessary to dig out bedding material and to cut or remove part of the polyethylene wrapping in ductile iron pipe and to remove part of the enamel undercoating and cement coating in steel pipe. When tapping steel pipe, the reinforcing wire in the cement mortar coating must not come in contact with the pipe or the corporation valve. After the taps are made, the polyethylene wrap in ductile iron pipe shall be repaired or replaced in accordance with Sheet 11 of the Standard Drawings, and the steel pipe recoated with coal-tar enamel and cement that conform to the Materials Specifications. Any bedding material removed during excavation shall be replaced in kind and compacted in accordance with section 7.11(A). D. Tapping Sleeves and Tees: Tapping sleeves or clamps are used to tap existing mains that are in service and under pressure without interrupting service. They are also used to tap new mains. Care shall be exercised to select sleeves and gaskets which are properly sized to fit the type and class of pipe to be tapped. Where four-inch (4") and larger tees and tapping sleeves are used, a thrust block shall be formed and poured behind the sleeve or tee to prevent possible damage to the main from pressure shocks which develop as valves are first opened. Tapping sleeves and tees shall conform to the Materials Specifications of these Engineering Standards. The tapping fitting required for a given type and of water main shall be as follows: TYPE OF MAIN AND SIZE OF TAP SIZE DUCTILE IRON STEEL OF (INCHES) (INCHES) MAIN 1 1-1[2 4 6 8 12 1 1-1l2 ~ 6 8 4" B B T N N N W W F N N 6" B B C T N N W W F F N 8" B B C C T N W W F F F 12" B B C C C T W W F F F "B" - Double-strap bronze clamp required.

Installation: Service laterals shall be designed and installed as shown in Sheets 38 thru 50 of the Standard Drawings for size two-inch (2") and smaller, and in conformance with Chapters 3, 5, 7, and 8 for size four-inch (4") and larger, except Where noted differ- ently in this Chapter. All joints in four-inch (4") and larger service laterals shall be firmly anchored to each other. Revised 07-92 6-5 Cover from top of service lateral to nearest gutter grade shall be a minimum of two feet (2') for two-inch (2") and smaller service laterals, a minimum of two and one-half feet (2-1/2') for four-inch (4") to eight-inch (8") service laterals, and three feet (3') for twelve-inch (12") service laterals. The service lateral shall be installed at lower depths if the Department determines that the installation at normal depth is not desirable. 6.08 CORPORATION VALVES, CURB VALVES, AND BRONZE FITTINGS Corporation valves provide the connection for the service lateral to the main for small services. By utilizing a corporation valve, a service can be connected to the main without taking the main out of service. Corporation valves are also used in a variety of other miscellaneous installations. Curb valves are set on the service lateral of small services on the inlet side of the meter box to provide a means to shut off the service lateral during repair or replacement of the meter. Miscellaneous bronze fittings (i.e., elbOWS, insulating couplings) shall be used where appropriate throughout the system, subject to the approval of the Department. Corporation and curb valves and miscellaneous bronze fittings shall conform to the Materials Specifications. 6.09 GATE VALVES AND STANDPIPES Four-inch (4") and larger gate valves of the same size as the service lateral shall be installed on the service lateral adjacent to the tee or tapping sleeve, on the inlet side of the detector check meter, and on both sides of the domestic meter. Four-inch (4") and larger gate valves used with steel or ductile iron service pipe within the service vault shall be flanged gate valves with cast iron or ductile iron bodies conforming to the Materials Specifications. All eight-inch (8") and larger gate valves installed in a vault or aboveground shall be supported by concrete stands or grout-filled concrete blocks. Unless installed in a vault or aboveground, all four-inch (4") and six-inch (6") gate valves shall be equipped with a cast iron vertical gate cap, steel split sleeve, and steel standpipe. All eight-inch (8") and twelve-inch (12") gate valves, not installed in a vault or above-ground, shall be equipped with a cast iron vertical gate cap, steel split sleeve, Revised 07-92 6-6 steel standpipe, and eight-inch (S") by six-inch (6") steel standpipe bottom.

See Sheet 13 of the Standard Drawings. 6.10 METERS All meters installed for billing purposes under the control of the Department, be obtained Department, and conform to the Engineering Standards. shall be installed until the proposed installation approved and the meter tested by the Department. Shall be from the No meter has been There are three (3) categories of meters currently being installed by the Department. Meters used to record volume of water for domestic needs are called domestic meters. Meters used to detect fire line usage are called detector check valves and are used on fire services. Dual-purpose meters used to measure combined large flows (for fire protection systems) and small flows (for domestic systems) are called F.M. (Factory Mutual) meters. The characteristics which meters are accuracy, sensitivity, cost, and ease of maintenance. are of special importance in durability, pressure loss, All meter installations will be inspected and approved by the Department. Installations which do not comply with the approved plans and specifications shall be made to conform prior to acceptance by the Department. A. Type of Meters: The various types of meters currently being installed in the Distribution System are positive displacement, compound, turbine, detector cheCk valve, and F.M. The type of meter installed shall be determined by the Department at the time of application based upon size, service and f low requirements, location of meter, and other conditions which may exist. B. positive Displacement Type Water Meters: Displacement meters are positive in action. The measuring Chambers supply a fixed quantity of water for each nutation or oscillation of the disc or piston when operated under Revised 07-92 6-7 positive pressure. Meters are available in five eights-inch (5/8") thru two-inch (2") sizes. One and one-half-inch (1-1/2") and two-inch (2")" meters are equipped with inlet and outlet oval type flanges. C. Compound and Turbine Meters: Compound meters consist of two meters in a single case separated by a check valve. One meter measures small flows and the other measures large flows. Compound meters are designed so that the small meter operates during low flows and as flows begin to increase, the check valve opens and the large meter takes over. When the large meter is in operation, the small meter is also in operation. Turbine meters are deigned to measure primarily large flows, and should not be used where the possibility of small flows (below the manufacturer's stated minimum flow) exists. D. Detector Check Valves: Detector check (DC) valves are assemblies that consist of a check valve in the main line and a positive displacement meter in the bypass line to detect flow. Detector check valves are designed to provide large, unmeasured flows for fire protection purposes with minimum pressure losses. E. F.M. (Factory Mutual) Meters: F.M. meters allow the consumer to use one service line to supply various combinations of domestic, private fire hydrant, and f ire sprinkler systems. F. M. meters measure large flows and are always used in combination with a smaller meter to measure the smaller flows through a bypass line. F. Meter setting: All meters shall be installed in a horizontal position and housed in a Department-approved box or vault. The Department will set all meters smaller than four-inch (4") except when the Contractor is specifically authorized in writing by the Department. G. Meter Bypass Lines: Bypass provisions are required for all four-inch (4") and larger domestic service installations, unless otherwise specified by the Department. Bypass designs mayor may not contain a meter but shall contain an independent control valve on each end of the installation. Bypass lines permit the consumer to have water while the domestic meter is being repaired or replaced.

(d) Separation distances specified in (c) shall be measured from the nearest edges of the facilities. (e) (2) Common Trench: water mains and sewer lines must not be installed in the same trench. When water mains and sanitary sewers are not adequately separated, the potential for contamination of the water supply increases. Therefore, when adequate physical separation cannot be attained, an increase in the factor of safety should be provided by increasing the structural integrity of both, the pipe materials and joints. B. Exceptions to Basic Separation Standards: Local conditions, such as available space, limited slope, existing structures, etc., may create a situation where there is no alternative but to install water mains or sewer lines at a distance less than that required by the Basic separation Standards. In such cases, alternative construction criteria as specified in Section D should be followed, subject to the special provisions in Section C. Water mains and sewers of twenty-four inches (24") diameter or greater may create special hazards because of the large volumes of flow. Therefore, installations of water mains and sewer lines twenty-four inches (24") diameter or larger should be reviewed and- approved by the health agency prior to construction. C. Special Provisions: 1. The Basic Separation Standards are applicable under normal conditions for sewage collection lines and water distribution mains. More stringent requirements may be necessary if conditions, such as high groundwater exist. Revised 07-92 8-13 2. Sewer lines shall not be installed wi thin twenty-five feet (25') horizontally of a low head (five (5) psi or less pressure) water-main. 3. New water mains and sewers shall be pressure tested where the conduits are located ten feet (10') apart or less. 4. In the installation of water mains or sewer lines, measures should be taken to prevent or minimize disturbances of the existing line. Disturbance of the supporting base of this line could eventually result in failure of this existing pipeline. 5. Special consideration shall be given to the selection of pipe materials if corrosive conditions are likely to exist. These conditions may be due to soil type and/or the nature of the fluid conveyed in the conduit, such as a septic sewage which produces corrosive hydrogen sulfide. 6. Sewer Force Mains: a. Sewer force mains shall not be installed within ten feet (10') horizontally of a water main. b. When a sewer force main must cross a water line, the crossing should be as close as practical to the perpendicular. The sewer force main should be at least one foot (1') below the water line. c. When a new sewer force main crosses under an existing water main, all portions of the sewer force main within ten feet (10') horizontally of the water main shall be enclosed in a continuous sleeve. d. When a new water main crosses over an existing sewer force main, the water main shall be constructed of pipe materials with a minimum rated working pressure of two hundred (200) psi or equivalent pressure rating. D. Alternate criteria for Construction: The construction criteria for sewer lines or water mains where the Basic Separation Standards cannot be attained are shown in Sheets 8 and 9 of the Standard Drawings. There are two situations encountered: Revised 07-92 8-14 Case 1 New sewer line new or existing water main. Case 2 New water main existing sewer. line. For Case 1, the alternate construction criteria apply to the sewer line. For Case 2, the alternate construction criteria may apply to either or both the water main and sewer line. The construction criteria should apply to the house laterals that cross above a pressure water main but not to those house laterals that cross below a pressure water main.

Installation: Concrete thrust blocks shall be provided for all bends and fittings subjected to an unbalanced hydrostatic force. Care shall be taken not to block outlets or to cover bolts, nuts, clamps or other fittings, or to make them inaccessible. Ductile iron pipe shall be polyehtylene encased prior to installing thrust blocks. If a large thrust block is to be poured, it shall be separated into sections by a suitable material. Sheet 12 of the Standard Drawings show sizes and shapes of thrust blocks. If, in the opinion of the Department, the soil-bearing capacity is not suff icient to provide adequate restraint based on minimum bearing areas shown on the Standard Drawings, then the minimum bearing area shall be increased to a size that will ensure adequate restraint. In every instance, the thrust block shall bear against undisturbed soil. Before placing concrete, all equipment for mixing and transporting the concrete shall be clean. All debris or water shall be removed from the place to be occupied by the concrete. Concrete shall be placed only in the presence of the Inspector unless inspection has been waived prior to the placement. B. Form Work: All forming for concrete thrust blocks shall be done by bulkheading around the shape of the thrust block with wood, burlap, or reinforced paper sacks filled with sand. Sacks shall be of a size easily handled when full, and shall be left in place in the trench. Wood forms shall be removed before backfilling. If the main must be placed into service immediately, wood may be used to form up thrust blocks. Wood forms shall be of such design as to support the thrust until the concrete has set and shall not be considered a substitute for the concrete thrust block. No horizontal struts or braces required for trench shor ing shall remain in the concrete thrust blocks. Prior to placing concrete, the forms and trench wall shall be inspected and approved by the Inspector. When concrete is deposited against the ground without the use of forms, the ground shall be thoroughly moistened or other provisions made to prevent the ground from absorbing water from the concrete. C. Minimum CUring Time: Newly placed concrete shall be allowed to set undisturbed for a minimum of twenty-four (24) hours. Revised 07-92 8-20 D. compaction of Fill Over Thrust Blocks: Backfill may be placed over thrust blocks after the surface has set sufficiently to resist the weight of the backfill.

Use of ordinary wire ties will not be allowed, nor will withdrawal of form ties through the walls be permitted. Forms may be made of wood or metal, subj ect to the approval of the Department. Where the finished concrete surface will be exposed, the forms shall be void of any irregularities, such as knotholes and chips. Before concrete is placed, all forms shall be carefully cleaned, all reinforcement securely tied, and all necessary openings blocked out. Any material necessary for the support of piping and valves shall be supplied by the Contractor. Forms shall not be disturbed until concrete has hardened sufficiently to permit their removal with safety. The removal of forms shall be carried out in such a manner as to ensure the safety of the structure. supervisory personnel shall be present at the time the forms are removed, and shall be responsible for the safety of this operation. B. Workability of Concrete: Concrete shall be of a consistency and composition that it can be worked readily into the corners and angles of the forms and around the reinforcement without permitting the materials to segregate, or free water to collect on the surface. No chlorides shall be added to the concrete mix. c. Mixing and Placing Concrete: Before placing concrete, all equipment for mixing and transporting concrete shall be clean. All debris or water shall be removed from the places to be occupied by the concrete. Wooden forms shall be thoroughly wetted or oiled. No concrete Revised 07-92 8-21 shall be placed until forms, reinforcing steel, and cleanup have been approved by the Department. concrete shall be placed only in the presence of the Department Inspector unless inspection has been waived prior to the placement. Concrete shall be conveyed from the mixer to the place of final deposit by methods which will prevent separation or loss of materials. All concrete placed shall have a temperature of at least 50 0 F (10 0 C), but not more than 90 0 F (32 0 C). Concrete shall be deposited, as nearly as practi- cable, in its final position to avoid segregation due to rehandling or flowing. No concrete that has partially hardened or been contaminated by foreign materials shall be deposited, nor shall retempered concrete be used. D. Finishing Concrete: All unformed surfaces shall be screeded and wood float-finished. Floor surfaces shall be roughened by light brooming following the wood float-finish. After the form work is removed, the voids in all formed surfaces shall be filled with patching mortar and form ties cut back and dry packed if necessary. E. Curing and Protecting Concrete: The finished concrete shall be protected for a period of three days and maintained at a temperature of not less than 50° F (10 0 C) . Precaution must be taken during hot weather to prevent cracks due to thermal contraction. Newly placed concrete shall be allowed to set undisturbed for a minimum curing time of twenty-four (24) hours. When concrete is deposited against the ground without the use of forms, the ground shall be thoroughly moistened or other provisions made to prevent the ground from absorbing water from the concrete. Concrete shall be protected with a Department-approved curing membrane immediately after removal of the forms, or on completion of finishing of floors or slabs. White membrane shall be used on non-water-bearing surfaces where concrete is exposed to the direct rays of the sun. The membrane shall be a nontoxic type. Revised 07-92 S-22 S.23 REINFORCING STEEL FOR CONCRETE STRUCTURES A. Installation: Reinforcing steel shall be accurately formed to the dimensions indicated on the drawings. Bends in bars shall be made cold. Bars with kinks or bends not shown on the drawings shall not be used. Splices shall be located where shown on the drawings. Splices at other locations shall be approved by the Design Engineer. Welded wire mesh shall be lapped one space and securely wired together. Before the reinforcement is embedded in concrete, the surfaces of the bars, and bar supports, shall be cleaned of heavy flaky rust, loose mill scale, dirt, grease, or other foreign substances which are objectionable. Reinforcement will be inspected for compliance with requirements as to size, shape, length, splicing position, and amount after it has been placed. B. Placing of Reinforcing Steel: Reinforcing steel shall be accurately placed and secured in position by using annealed iron wire ties so that it will not be displaced during the placing of the concrete. Chairs, hangers, spacers, and other supports for reinforcement may be concrete, galvanized, or plastic coated metal, or other approved material. steel reinforcement shall be protected by the thickness of concrete indicated on the plans. Where not otherwise shown, the thickness of concrete over the reinforcement shall be as follows: L Where concrete is deposited against the ground without the use of forms, not less than three inches (3"). 2. Where concrete is exposed to the weather, or exposed to the ground but placed in forms, not less than two inches (2") for bars more than five eight-inch (5/S") diameter and one and one-half inches (1-1/2") for bars five eight-'inch (5/S") diameter or less. 3. In slabs and walls not exposed to the ground or to the weather, not less than three quarter inches (3/4") • 4. In all cases, the thickness of concrete over the reinforcement shall be "clear" and at least equal to one and one-half (1-1/2) diameters that of the reinforcement bars. Revised 07-92 8-23 8.24 HYDROSTATIC TESTING No hydrostatic testing shall be made on any portion of the pipeline until field-placed concrete has had adequate curing time as defined for thrust blocks in Section 8.21 of these Standards. The Department shall be notified twenty-four (24) hours in advance of testing. The main being tested shall not be restrained against the existing main or its appurtenances. Testing against shut gate valves is prohibited. All testing shall be made in the presence of the Department Inspector. Only the following methods are acceptable for supplying potable water for hydrostatic testing: 1. Water may be taken from a nearby pressurized water source which has been previously disinfected, tested and accepted by the Department, such as a fire hydrant. 2. water may be delivered to the site in a disinfected water truck having a minimum capacity of three hundred (300) gallons. The water truck shall be used exclusively for the transportation of potable water. 3. Any previously tested, disinfected and Department- accepted main which is pressurized and is to serve the new main extension may be tapped on the pressurized side of the closed valve. In any event, the method of supplying water as well as the source of water for hydrostatic testing shall be certified and approved by the Department. Use of barrels, sani tary or otherwise, to supply water for hydrostatic testing is strictly prohibited. The Department will not furnish the calibrated meter or the pump required for testing. The main shall be properly back- filled and shall be in a state of readiness for testing. All bulkheads, pumps, taps, and appurtenances necessary to fill the main and maintain the required pressure shall be in place. The main shall be filled with water at a rate which will not cause any surges or exceed the rate at which the air can be released. The main shall be subjected to a hydrostatic pressure of one and one-half (1-1/2) times the maximum static pressure at the point of testing and not less than one and one-quarter (1-1/4) times the maximum static pressure at the highest point along the test section by means of a continuously operating pump, equipped with a bypass valve for regulating pressure. The specified test Revised 07-92 8-24 pressure shall be based on the elevation of the lowest point of the line or section under test and corrected to the elevation of the test gage. All air in the main shall be properly purged. Where blow-offs or hydrants are not available or are not effective in purging air from the line, the Department shall require a tap to purge the main. The location and size of tap shall be at the Department's discretion. The test pressure shall be maintained at plus or minus five (5) PSI for a period of two (2) continuous hours during which an examination of the main shall be made, and any leaks repaired. Any pipe or fitting found to be faulty shall be removed and replaced. No leakage shall be allowed through the bonnet of line valves. Any valve leaking through the bonnet shall be repaired in place or removed and replaced. Cutting and replacing pavement, excavating, and backfilling may all be necessary parts of locating and repairing leaks discovered by pressure testing of pipe. After all visible leaks have been stopped, the full test-pressure shall be maintained for two (2) continuous hours. Leakage for steel pipe with welded joints shall not be allowed. Allowable leakage for ductile iron pipe shall not exceed the amount determined by the following formula: L = S = D = P = L = SDP/133,200 Allowable leakage (gallons per hour) Length of pipe tested (feet) Nominal diameter of the pipe (inches) Average test pressure during the test (PSI) Testing against closed valves is prohibited. When fire hydrants are in the test section, the test shall be made against the closed fire hydrants. Should testing show a leakage rate in excess of the rates computed, the main shall not be accepted. The main shall be repaired and retested as described in this section until it meets the test requirements. 8.25 DISINFECTION All main extensions will be disinfected by the Department before they are accepted by the Department. The Contractor shall install temporary valved inlets at points designated by the Inspector to enable disinfection of the mains. Revised 07-92 Disinfection of the completed main installation shall be done after hydrostatic testing. Before filling the pipe with water, the pipe shall be clean and free of debris to the satisfaction of the Department's Inspector. The Department shall be notified at least forty-eight (48) hours prior to the desired disinfection time. 8.26 CONNECTIONS TO THE DEPARTMENT'S SYSTEM A. Connections: Connections to the Distribution System are generally made by the Contractor. Connections shall be performed in a neat and workmanlike manner in accordance with Sheets 23 thru 26 of the Standard Drawings. The Department's Inspector shall be present at all times during construction of the connection. The connection shall be subject to approval by the Department. Under no circumstances shall a non-disinfected main, which cannot be isolated, be connected to a disinfected main. The Department is not responsible for water tightness of its valves on existing facilities. If existing valves leak, the Department will assist in reducing the influx of water, but the Contractor shall use methods at his or her own disposal to work with the resulting leakage. B. Operation of Valves: In connecting to the Department's system, it may be necessary to operate existing Department valves. All line valves in the Department's system shall be operated by Department personnel only. The Contractor shall give the Department at least forty-eight (48) hours' notice to arrange for operation of the valves. Both the Contractor and the Department's Inspector shall be present when the valves are operated. C. Interruption of Service: The Contractor shall provide written notification twenty-four (24) hours in advance to all affected Department customers of temporary water outage on contractor-installed connections that cause interruption in service. 8.27 ACCEPTANCE AND RELEASE FOR WET TAPS A main will be accepted by the Department and released for wet taps only when the following conditions have been met: Revised 07-92 8-26 A. The main and all appurtenances have been installed to the satisfaction of the Department and·· all pertinent notes and measurements have been made. B. The main has been successfully pressure tested to the requirements of Section 8.24. C. Water Quality Division has disinfected and released the main for taps. Revised 07-92 9.01 GENERAL CHAPTER 9 SIXTEEN-INCH 116") AND TWENTY-INCH (20") SUPPLY MAINS New developments are commonly designed with curved streets, only one or two access roadways, and many cul-de-sacs. Mains supplying these subdivisions often cannot be sized using the hydraulic grid system common in most of Los Angeles. In some instances, the maximum water demand within these developments exceeds the allowable design capacity of a twel ve- inch (12") Distribution Main, but is often considerably under that of a twenty-four-inch (24") Trunk Line. As a result, it has become necessary to install sixteen-inch (16") and twenty-inch (20") pipe to supply this type of development. 9.02 OTHER STANDARDS TO APPLY Chapter 9 addresses only sixteen-inch (16") and twenty- inch (20") Supply Mains. All standards that apply to four-inch (4") through twelve-inch (12") Distribution Mains shall apply to sixteen-inch (16") and twenty-inch (20") Supply Mains along with the requirements or exceptions discussed in this Chapter. In case of conflict with any other Chapter or Section in these Standards, this Chapter shall govern for sixteen-inch (16") and twenty-:-inch (20") pipe. 9.03 DESIGN Sixteen-inch (16") and twenty-inch (20") Supply Mains shall be designed in accordance with Chapters 3 and 5 of these Standards and the following additional requirements: A. Only welded steel pipe and ductile iron pipe that conform to the Materials Specifications or better shall be used. The Applicant should be aware that large diameter pipe and fittings may require long lead times and it is the responsibility of the Applicant to assure materials are on hand. B. Restrained joints for ductile iron pipe installations shall be of the boltless type, capable of deflection after assembly, and designed for a minimum working water pressure of two hundred and fifty pounds-per-square-inch (250 psi). Revised 07-92 9-2 C. Line valves shall be optimally placed such that outages to services during future repairs or construction are minimized. Generally, this will require the ability to isolate and alternately supply all Distribution Mains (or Supply Mains) extending from the Supply Main but in no instance should the spacing between valves exceed one thousand two hundred feet (1200'). Line valves shall be of the same size as the main or one diameter size smaller when specifically approved by the Department. The size and type of valve to be used shall be clearly indicated on all submitted drawings. A rectangular vault or pipe manhole used as a standpipe shall be used to house sixteen-inch (16") and larger line valves. See Sheet 37 of the Standard Drawings for a steel pipe manhole assembly. If the Department requires the installation of remote control and monitoring equipment for its operation, the line valve shall be a butterfly valve with a rectangular vault housing both the electric motor operator and telemetering equipment. Each installation will require individual approval. D. Blow-off assemblies, as shown on Sheet 34 of the Standard Drawings, shall be installed at all low point in Supply Mains and wherever a Supply Main dead ends unless a fire hydrant which can serve as a blow-off is provided at these locations. E. Automatic air valves (air release valves (ARV), air and vacuum valves (AW) and combination air valves (CAV)) shall be required for Supply Mains at the discretion of the Department. Air valve assemblies, as shown on Sheet 35 of the Standard Drawings, are generally installed at high points in the Supply Main, where there is an abrupt change of slope, and at the downslope side of line valves, or as determined by the Department. F. Each Supply Main shall be examined individually to determine special conditions and/or requirements (e.g., air valves, check valves, etc.). G. A galvanic cathodic protection system shall be provided on all steel Supply Mains in accordance with sections 5.07(B) and 8.11(F), and the following table: Revised 07-92 1. 2. 3. 4. 5. 6. 7. 9-3 Description Pre-Ass'd Ins.

Revised 07-92 9-4 9.04 INSTALLATION Installation of sixteen-inch (16") and twenty-inch (20") Supply Mains will generally be done by the Applicant or the Applicant's contractor. The Contractor shall be prequalified by the Department for the installation of sixteen-inch (16") and twenty-inch (20") pipe. As with four-inch (4") through twelve-inch (12") mains, the Department reserves the right to install sixteen-inch (16"), and twenty-inch (20") Supply Mains when it is in the best interest of the Department. This determination is solely at the discretion of the Department. The Applicant shall pay all costs for extending mains whether installed by its contractor or by the Department. Line and grade will be established by, and as-constructed surveying done by the Department at applicant· s expense, or when specifically approved by the Department, by a Professional Engineer or by a Land surveyor licensed to practice in the State of California or by its authorized representative in accordance with sections 2.09 and 2.10. Revised 07-92 CHAPTER 10 TWENTY-FOUR-INCH (24") AND LARGER TRUNK LI-NES 10.01 GENERAL It is the policy of the Department to design twenty-four-inch (24") diameter and larger Trunk Lines to ensure a high-quality, uninterrupted, low-maintenance water service system. The function of Trunk Lines is more important than that of Supply or Distribution Mains, and the risk is correspondingly greater if the Trunk Lines are improperly designed or installed. The Department reserves the right to design and install Trunk Lines when to do so is in the best interest of the Department. All Trunk Lines which will become part of the Department system will be designed by the Department unless other arrangements are made. Trunk Lines will be installed by the Applicant when practical. Design of the Trunk Line should proceed only after approval to design and/or construct the Trunk Line is received from the Department. The concept, size, location, and any other pertinent details shall be reviewed by the Department prior to the submittal of plans and specifications required by Section 2.06. The Applicant shall pay all costs for the design and construction of Trunk Lines including those incurred by the Department for inspection, testing of materials, and other Department services. 10.02 OTHER STANDARDS TO APPLY Chapter 10 addresses only Trunk Lines. All Standards that apply to four-inch (4") through twelve-inch (12") Distribution Mains and to sixteen-inch (16") and twenty-inch (20") Supply Mains shall apply to Trunk Lines along with the additional requirements and exceptions stated herein. In case of conflict with any other Chapter of these Standards, this Chapter shall govern for Trunk Lines. 10.03 PRELIMINARY INVESTIGATION If the Applicant is conduct its own preliminary requirements shall be met: allowed by the investigation, Department to the following A. A subsoil investigation shall be performed by a geotechnical engineer from exploratory holes dug to determine design values, slide areas, fault crossings, Revised 07-92 10-2 backfill suitability of the soil, presence of groundwater or bedrock, and any other condition which may affect the construction of the Trunk Line. Test holes shall be dug with a maximum spacing of seven hundred and fifty feet (750') and at railroad, highway, and river crossings. soil resistivity readings shall be taken at depths of 5 feet and 10 feet. B. A stationed alignment of the proposed Trunk Line is required to define the route with lines, angles, and curvatures referenced to land corners and other official survey control points when available. No negative stationing is allowed.

All cross section data shall be entered into field books. E. All utility crossings or close utility interference shall be exposed by digging test pits. Field books shall be used to record the size, nature, and location of the interference by station offset and elevation. Revised 07-92 10-3 F. All survey data compiled in the determination of the route location, the extent of the interference, the centerline profile, the cross sections, and level loops shall be entered into field books provided by the Department and submitted with the plans and specifications. 10.04 DESIGN Trunk Lines shall be designed in accordance with all other applicable Sections of these Standards and the following additional requirements: A. Pipe shall conform to the Materials Specifications. Trunk Lines shall be of welded steel but may be of reinforced concrete cylinder, prestressed concrete cylinder, or ductile iron if specifically approved by the Department. The design criteria for reinforced concrete and ductile iron pipe shall be those currently specified by the Department for Trunk Lines. Prior to construction, the Contractor shall submit for approval by the Department, the manufacturer's detailed shop drawings, design calculations, material list, laying schedule, and marking diagram. The Applicant should be aware that large diameter pipe and fittings may require long lead times and it is the responsibility of the Applicant to assure materials are on hand. B. Line valves shall be placed such that outages to consumers during future repairs or construction are minimized. Generally, this will require the ability to isolate and alternately supply all mains extending from the Trunk Line, but in no instance should the spacing between valves exceed one (1) mile. Line valves shall be butterfly valves with flanged-end connections conforming to the Material Specifications. A pipe manhole used as a standpipe or a rectangular vault shall be used to house each valve. The valve installation shall include a tap on each side of the valve for chlorination and/or air release. See Sheet 37 of the Standard Drawings for a typical steel pipe manhole assembly. If the Department requires the installation of remote control and monitoring equipment for its operation, the line valve shall be a butterfly valve with a rectangular vault housing the electric motor operator and telemetering equipment. Each installation will require individual approval. Revised 07-92 10-4 C. Blow-off assemblies shall be installed at all low points, dead ends, and at line valves where the Trunk Line slopes toward the valve. See Sheet 34 of the Standard Drawings for blow-off installations for sixteen-inch (16") and larger steel pipe. D. Automatic air valves (air release valves (ARV) , air and vacuU1l1 valves (AVV) and combination air valves (CAV» assemblies are generally installed at high points, where there is an abrupt change of slope, and at the downslope side of line valves, or as determined by the Department. See Sheet 35 of the Standard Drawings. E. Access manhole assemblies as shown on Sheet 36 of the Standard Drawings shall be installed at intervals not exceeding one thousand feet (1000 ') unless otherwise approved by the Department. Pipe manhole assemblies similar to those required on large line valves (Sheet 37 of the Standard Drawings) shall be installed over every other access manhole installed under paved finished surfaces, or where required by the Department. F. The location and design of outlets, tie-ins to any existing or proposed facilities, and bulkheads shall be approved by the Department. G. Each Trunk Line plan shall be examined individually to determine any special condition and/or requirements by the Department (e.g., pressure regulating valves, telemetering, pitots, etc.). H. Vertical clearance between the Trunk Line and crossing interferences shall be at least one foot (1 I ) • Horizontal clearance shall be at least five feet (5'). I. All welded steel Trunk Lines shall be provided with a galvanic cathodic protection system designed, installed and tested by a Corrosion Engineer (someone under the direct supervision of, or by a Corrosion Specialist Certified by the National Association of Corrosion Engineers) registered by the State of california). The system shall be SUbject to approval by the Department. 10.05 PLANS AND SPECIFICATIONS Detailed plans and specifications for Trunk Lines shall be prepared on mylars provided by the Department for approval in accordance with Section 2.06. Plan and profile scales shall be Revised 07-92 10-5 one inch (1") equals forty feet (40') horizontal, and one inch (1") equals ten feet (10') vertical. In addition to the requirements of Chapter 2, the plans shall contain the following information and exceptions: A. A plan view showing: 1. The proposed alignment of the Trunk Line and the location of outlets, valves, blow-offs, air valves, pitots, thrust blocks, bends, reducers, bulkheads, and connections to all facilities. 2. All existing and proposed substructure utilities and obstructions complete with dimensions to the Trunk Line. 3. All survey bench marks and alignment data. B. Top-of-pipe profile showing: 1.

EXHIBIT 5 SAMPLE AGRREMENT FOR INSTALLATION AND TRANSFER OF TITLE OF WATER SYSTEM FACILITIES AGREEMENT NO. WO- This Agreement is entered into and effective as of by and between the DEPARTMENT OF WATER ANGELES, hereinafter referred to as the "Developer", who agree as follows: The Developer is the owner of certain land described as Tract No. and as more fully (or further} shown on Exhibit "A" attached hereto. In developing this land, the Developer is desirous of obtaining a water supply adequate for domestic uses and public fire protection purposes and is desirous of Water System clearance for this project. In order to provide facilities for a water supply to said land, it is the intention of the parties to this Agreement that the Developer will furnish and install those water mains, fire hydrants, service laterals, valves, and all pertinent fittings, and other facilities required for a complete water system to serve the land shown on Exhibit "A". In order to implement the foregoing and in consideration of the terms and conditions herein contained, the parties further agree as follows: 1.0 Developer shall design and construct, at the Developer's sole expense, the water facilities and appurtenances in accordance with Department-approved final plans, and in accordance with Department-approved design standards and specifications, and the terms and conditions of this Agreement. 1.1 Design shall be by a Professional Engineer registered in the state of California, hereinafter referred to as the "Design Engineer", in accordance with the Department's Water Operating Division's latest Engineering Standards Manual and Standard specification No. DWPWS-D101. 1.2 A copy of the Department's Engineering Standards Manual and Standard Specification No. DWPWS-DIOl will be provided to the Developer upon payment of applicable charges. 2.0 The Department, at the Developer's expense, shall review the Developer's plans for the purpose of ensuring the adequacy of the design and conformance with the Department's standards and specifications. The Department reserves the right to add, delete, modify, change, or amend any or all the plans and specifications. - 2 - 2.1 In the event that the property to be developed includes multiple residential, condominiums, commercial or industrial uses, site plans, grading plans and any available plumbing plot plans will be furnished to the Department by the Developer. 2.1.1 During the course of the development and construction of the project, it is recognized that the City of Los Angeles or other regulatory authority may require, or the Developer may agree to, changes in existing streets, facilities or installations which in turn may require the relocation, replacement or addition of water system facilities. In the event that any such changes are required, or agreed to, the Developer shall, within 30 days thereof, submit to the Department for its review and approval the final plans and specifications detailing the Developer's arrangements to accomplish such work. The Developer shall perform any additional water facility work at the Developer's sole cost. All work performed pursuant to this paragraph shall be subject to the terms and conditions of this Agreement and shall be considered a part hereof. 2.2.0 During the course of the development and construction of the project, it is further recognized that unforeseen circumstances including, but not limited to, surface or subsurface geological and earth features and the presence of artificial structures and/or equipment may prevent the construction of the system as theretofore designed and that changes in the design and construction will be required because of the aforementioned unforeseen circumstances. In such event, the Design Engineer will modify the design to accommodate said unforeseen circumstances to the satisfaction of the Department. The Developer will pay the Department any applicable costs associated with such redesign in accordance with paragraph 12 herein. 2.2.1 The Department retains in its sole and exclusive discretion, the option to perform such additional work itself. In the event the Department exercises such option, the Developer shall pay the Department's current costs in accordance with Paragraph 12 herein, for such additional water facility work. 3.0 The Developer shall procure, at the Developer's own expense, all licenses, guarantees, approvals and certificates of inspection which are required by the laws, rules, regulations or codes of all government bodies having jurisdiction over said construction and property and shall, in addition, comply with all the requirements thereof. 3.1 Excavation/resurfacing permits will be secured by the Department at the Developer's expense. Permits/easements to install, maintain and operate water System facilities in private property shall be secured by the Developer at the Developer's own expense. 4.0 The water system facilities to be installed pursuant to this Agreement will become an extension of the distribution system of the Department.
