Panigan-Tamugan watershed study to be completed in 2020

The Integrated Watershed Management Plan involving the Panigan-Tamugan section is expected to be completed sometime next year.


This was disclosed by Cirilo “Ones” Almario III, general manager of Apo Agua Infrastructura Inc., the joint venture between Aboitiz Equity Ventures (AEV) and J.V. Angeles Construction Corporation (JVACC).

In partnership with the Watershed Management Council (WMC) and the Davao City Water District (DCWD), Apo Agua crafted an integrated management watershed plan particularly to Panigan-Tamugan watershed where they are going to source water for the P12.6 billion bulk water project.

The surface water of Panigan-Tamugan Rivers was identified as the City’s alternative source of drinking water. In 2015,

Apo Agua and DCWD signed an agreement for the development of a bulk water supply within the Panigan-Tamugan Watershed. Under the deal, Apo Agua Infrastructura will develop and supply around 300-350 million liters per day (MLD) of potable water from the Tamugan River to the pipelines of the DCWD, for distribution.

The WMC has required Apo Agua Infrastructura to come up with a watershed management plan for Panigan-Tamugan segment, where they will tap surface water from Tamugan river. This project aims to address the shortage of water supply in the city as the current water source, Talomo-Lipadas watershed, needs to recover. The WMC has also approved and endorsed the project to the Davao City Council because it will provide solution to the growing concern of insufficiency of drinking water supply in the city.

“Right now we are finalizing the plan and what we are doing right now is do a baseline study on what’s there in Panigan-Tamuigan Watershed.  Ano yung mga plantations na nandoon, what type of residents are there, if there are pineapple or banana plantations, are they using harmful pesticides. So that we can better asses on what’s going to the river,” Almario said.

Almario also said they are currently selecting consultants for the crafting of the study. He is hopeful the study, to be funded by Apo Agua, will be available sometime next year.

“We are still crafting the scope na kailangan gawin. It will really depend on the proposal of the consultants on how long will it take and the cost of the study,” he said.  

Apo Agua is scheduled to start laying the treated water pipes in October this year. The 60- kilometer treated water pipeline will start from the water treatment facility and end in DCWD’s five existing water systems namely Dumoy, Calinan, Tugbok, Panacan and Cabantian as well as three additional new water systems in Talandang, Mandug, and Indangan.
