Apo Agua Infrastructura, Inc. is building one of the Philippines’ largest private bulk water supply facilities that will supply over 300 million liters per day of safe and sustainable water to the Davao City Water District for the people of Davao City.
The company entered into an agreement with DCWD to shift the dependence of Davao City’s main water supply from groundwater wells to the more sustainably sourced surface water of the Tamugan River.
We are committed to develop sustainable water infrastructure and utilize technologies that will
uphold the welfare of our communities and the environment.
We play a key role in nation-building by providing reliable services and innovative solutions in
bulk water infrastructure to uplift the lives of Filipinos today and of generations to come.
We ensure delivery of safe drinking water that is compliant with the national drinking water
standards to the communities we serve.
Apo Agua is a subsidiary of the Aboitiz InfraCapital, Inc. (AIC), the fifth leg and newest business venture of the Aboitiz Group that undertakes all infrastructure and infrastructure-related investments. In March 2015, Apo Agua entered into a bulk water supply agreement with the Davao City Water District (DCWD) for their Davao City Bulk Water Supply Project (DCBWSP). The agreement involves the construction of one of the country’s largest private bulk water supply facilities. With the Project, Apo Agua will supply over 300 million liters per day (MLD) of safe and sustainable water to DCWD, which will benefit the more than 1 million people of Davao City.
Introducing the Davao City Bulk Water Supply Project
The Davao City Bulk Water Supply Project (DCBWSP) of the Davao City Water District (DCWD) is a strategic infrastructure initiative that will shift the dependence of Davao City’s main water supply from groundwater wells to the more sustainably-sourced surface water from the Tamugan River.
DCWD has been using groundwater for almost 45 years. There is an urgent need to look for an alternative and sustainable water source that will be in conjunctive use with the current groundwater source, as the water demand in the City is rapidly increasing due to population growth and urbanization.
By tapping the Tamugan River, the project will access both the right quality and ample quantity of water in order to allow the DCWD to temporarily shut down many of its groundwater well sources. This, in turn, will ensure the preservation of the city’s water table and save it from irreversible environmental degradation such as land subsidence and saltwater intrusion–both typical results of groundwater over-extraction.
The DCBWSP involves two components: Part A component by Apo Agua will cost PHP 12.6 billion and involves the construction of intake facilities, a water treatment facility and treated water pipelines; Part B which costs two billion-pesos and is being handled by the DCWD, involves the tapping and interconnecting of pipes, installation of reservoirs and laying of distribution lines.
Apo Agua is committed to developing a sustainable bulk water supply for Davao City. A first in the country, the project’s water treatment facility will be powered by renewable energy sourced from a two (2) Megawatt run-of-river hydroelectric power plant. This is a pioneering innovation called the “water-energy nexus” concept. The raw water will first pass through the run-of-river hydroelectric power plant to generate energy, which will be used to power the water treatment facility and produce treated water. This treated water will then be distributed to the reservoirs of DCWD.
Set to be one of the country’s largest private bulk water supply facilities, the project will provide the DCWD with over 300 million liters per day (mld) or 109.5 million cubic meters (cu.m.) per year of safe drinking water. This will serve about 295,000 additional households in the remaining 40% of DCWD’s unserved areas and enable them to significantly expand its service area to six new barangays, particularly those in the Panacan and Cabantian water systems, among other areas experiencing low water pressure and intermittent water supply.
The treated water will be istributed to over one million Davaoeños through the DCWD’s five existing water systems, namely: Dumoy, Calinan, Tugbok, Panacan, and Cabantian, as well as via three additional new water systems at Talandang, Mandug, and Indangan.
Apo Agua began its three-year construction phase with engineering design works in 2018 and targets to commence operations by 2022.
Questions? We may have the answers for you.
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.
