Appraisal of Rainwater Harvesting in ASCOT Engineering Zabali Campus Baler Aurora
Downloads
One of the problems encountered by the engineering students and faculty and staff members of Aurora State College of Technology (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 main 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 harvesting is considered by the researchers and in this research, the researchers assessed the potential of rainwater harvesting using the 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. Based on 10-year rainfall data from PAGASA Baler Station Complex which is Located approximately 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 maybe met during the driest month of the year.
