The Philippine Water Supply and Sanitation Master Plan (PWSSMP) serves as the national action plan to achieve universal access to safe, sufficient, affordable and sustainable water supply, hygiene and sanitation by 2030. Linked to the national water supply and sanitation (WSS) targets, the PWSSMP is grounded on the realities of every region as gathered from knowledge and insights shared by over 1,000 representatives across the country. The PWSSMP defines the activities, responsible agencies, and the budget necessary to grow the WSS sector to match the scale of the country’s need. The proposed policy, economic, environmental and engineering solutions factored in different levels of development to match the specific realities and requirements on the ground, recognizing the fact that situations, conditions and challenges vary from one community to another.
