Abstract
Leyte is a province in the Philippines that has an abundant amount of rainfall with mean annual rainfall of 2589.72 mm. The regular occurrence of typhoons in the province of Leyte has brought a huge amount of rainfall to the province. However, the rainwater becomes waste flowing down the drains causing flood, especially in urban areas. LGUs has not yet introduced a framework to harvest the huge amount of rainwater and utilize its equivalent stored potential energy. With this, the study introduces rainwater harvesting system that incorporates the utilization of energy stored in the rainwater harvesting system. The study calculates the equal amount of energy produced using rainwater. The rainwater energy harvesting includes the following: the floor area and roof area of residential buildings in Leyte province as catchment facility, the rainfall precipitation from two (2) PAGASA weather stations, and the number of rainy days in the Leyte province. The study employed theoretical power and energy equations in computing the equivalent stored potential energy by utilizing the average rainfall amount in the province with the average floor area specified from the approved building permits as of first quarter of 2022 with an initial building height of 5 meters.
