APPRAISAL OF RAINWATER HARVESTING IN ASCOT ENGINEERING ZABALI CAMPUS BALER AURORA

One of the problems encountered by the engineering student s and facult y and staff members of Aurora State College of T echnology (ASCOT) is the water supply for toilet and urinal flushing . This problem is attributed to the location of the area which is 50m above sea level. The m ain water source of the campus is the water coming from water falls which requires pipelines that are vulnerable from heavy damage during natural disasters and illegal intrusion. To address the scarcity, rainwater harves ting is considered by the researchers and in this research, the researchers assessed the potential of rainwater harvesting using t he roof of an existing building in the area . The result shows that harvesting water from rainfall can become a solution in the scarcity of water in the area. Base d on 10 - year rainfall data from PAGASA Baler St ation Complex which is Located a pproximately 4.3 km from the location of the study that on average, during December, November and October the amount of rainfall can fulfill the demand of water for toilet and urinal flushing up to 102.54 %, 76.98% and 75.40% respectively. The total area of rainwater collector in this study is about 186.87 square meter. Data also shows that on average, the month of August has the minimum potential of fulfilling the demand water for the area but by increasing the area of collector by 68%, 100% of the demand for this specific purpose ma ybe met during the driest month of the year
