Q.1. What is the Davao City Bulk Water Supply Project?


The Davao City Bulk Water Supply Project (DCBWSP) is a project of the Davao City Water District (DCWD) in partnership with Apo Agua Infrastructura, Inc. (Apo Agua). It will tap Tamugan River as surface water source and utilize 100% renewable energy-run water treatment facility to supply safe and sustainable bulk water supply for Davao City, ensuring a more resilient and self-sufficient system.

Q.2. What are the differences in the roles of DCWD and Apo Agua?


Apo Agua will handle Part A component of the project which involves the construction of raw water facilities, hydroelectric power plant, water treatment plant, treated water pipelines, and facilities for various off-take points in the city. Apo Agua will supply DCWD a minimum contracted volume of 300 mld of treated bulk water from the Tamugan River for a period of 30 years.

DCWD on the other hand will handle Part B component of the project which involves the construction of primary transmission or distribution pipes and storage facilities in various portions of the city. Distribution of treated water to residential, government, commercial, industrial and bulk water end-users will remain solely with DCWD.

Q.3. Why do we need the project?


DCWD has been using groundwater for almost 45 years. There is a need to look for an alternative water source in order to limit the extraction of groundwater and allow the aquifers to rest. The water demand in the City is rapidly increasing due to population growth and urbanization. There is a need to increase the available water supply to meet this growing demand.

Q.4. What are the key features of the Project?


A unique component of the project is a pioneering innovation which is the “water-energy nexus” concept. The water will first pass through a run-of-river hydroelectric power plant which will produce sufficient renewable energy to supply the power demand of the succeeding water treatment plant that would produce safe water to the reservoirs of DCWD.

Q.5. What is the geographical service coverage of this project?


The project will supply treated water to five existing water systems (Dumoy, Calinan, Tugbok, Panacan and Cabantian) and three additional water systems (Talandang, Mandug and Indangan) of DCWD.

Q.6. When will this project start its operation?


Apo Agua began its construction phase with engineering design works in 2018 and targets to commence operations by 2022.
