CONCLUSION AND RECOMMENDATION Summary • It was evaluated to determined the water distribution of SPAMAST campuses. valuing 597.00 m³.00 m³ on March 2013 . to design and estimates the cost for construction of Rainwater harvesting system in campuses.to analyze the rainwater harvesting potential of SPAMAST campuses. • The Highest water consumption data of SPAMAST-CAS was recorded on July 2014. 00 m³ in the month of October 2014. Academic building. the highest consumption occurred from January 2013 to October 2014 was the cluster-dormitory or meter no. The women’s dormitory and the General education building in Buhangin campus.960704557 valuing 368. Education building and the General education building in SPAMAST-Main Malita. The Dormitory.00 m³ on September 2014 . Among the Four clusters.  nine potential rainwater harvesting can be utilized. Administration building. In SPAMAST-Malita. only the Model house has almost no water consumed in 2013 and the largest value of water consumed was 232. one from SPAMAST-CAS Digos where the General Education building. . FMS building.  The total cost estimates for construction of rainwater harvesting system in SPAMAST Campuses was 924.92 pesos. In designing rainwater harvesting system the utilization of water is need to be considered in order to lessen the procurement of water from the local water provider and the erosion of river banks will be lessened. .663.  The design is focused in flushing of comfort rooms and for the irrigation purposes.  Rainwater harvesting is seems to be a perfect replacement for surface & ground water as later is concerned with the rising cost as well as ecological problems.  It was finally concluded that implementation of RAINWATER HARVESTING PROJECT to the campuses of SPAMAST. .Conclusion The following conclusions were drawn:  the water that procured from water districts will be decreased with the help of this technology.  There should be monthly data of consumption of water that are pump underground in every campus.  There should be maintenance in water distribution lines in SPAMAST campuses. and introduced the benefits of rainwater harvesting system in the community.Recommendation  There is a need to conduct seminar and training on the current issues on water problems and purchasing. . water is highly a precious natural resource which is always in high demand today and thus. . RAINWATER HARVESTING AT SPAMAST campuses is highly recommended. Therefore.
