Abstract

The Angat-Ipo-La Mesa water system is the main source of water for the Greater Manila Area. Due to the increasing population, climate change, and the lack for new source of water supply, water shortage is imminent. To address this problem, first, this study aims to know when will the demand overtake the supply using Euler approximation method. The resulting projection can identify how much water will be needed in the future and when should a new source for water supply be developed. Next, as a short term solution to water scarcity, improvement on water allocation should be done. The researchers developed a water allocation policy under El Niño phenomenon that will satisfy the demand and maintain an above critical water level of the Angat dam. With the help of this study, water security and security from droughts can be provided for the people of the Greater Manila Area.
