Since December 1, 2023, Apo Agua has been supplying bulk water to DCWD’s Calinan, Tugbok, Riverside, Dumoy (Panorama), Cabantian, and Panacan water supply systems (WSS). Water supply availability and pressure have since significantly improved, especially in areas that have been experiencing intermittent water supply.
Although Apo Agua’s Water Treatment Plant (WTP) is designed to treat raw water from the Tamugan River, instances of excessive heavy rains in the upland areas of the Panigan-Tamugan Watershed can cause the river’s turbidity levels to exceed operating parameters. Turbidity measures water clarity and shows the amount of solids and sediments present. High turbidity makes the water appear cloudy or muddy.
During instances of high turbidity levels that exceed operating parameters, occurring only 5-10% of the time, the WTP will temporarily stop production while maintaining a controlled and reduced flow to supply water to DCWD. The remaining water in the treated water reservoir, which can supply for an additional 10-12 hours, will be used until production resumes once raw water quality meets the specified parameters.
Operational enhancements are also being implemented to maximize production efficiency without compromising water quality.
Rest assured that Apo Agua is in constant coordination with the DCWD to provide advance notice of high turbidity in the Tamugan River, enabling the ramping up of groundwater source production. Conjunctive use of both surface water from Tamugan River and groundwater sources is being implemented by DCWD to ensure continuous water supply.
