Manila Water Strengthens Water Security with Near Completion of Kaysakat Water Treatment Plant

Manila Water is on track to complete the 220 million litres per day (MLD) Kaysakat Water Treatment Plant in Antipolo City this year, further strengthening water supply reliability in the East Zone amid the recurring threat of El Niño and declining water levels at Angat Dam.

The Kaysakat Water Treatment Plant is a key component of the Wawa-Calawis (Kaysakat) Water Supply System Phase 2 and forms part of Manila Water’s long-term strategy to diversify its raw water sources and reduce dependence on Angat Dam, which supplies majority of Metro Manila’s potable water needs.

With a project cost of PHP5.44 (USD0.09) billion, the Kaysakat Water Treatment Plant is designed to treat raw water from the Wawa Dam and deliver an additional 220 MLD of potable water to Manila Water’s distribution network. Once operational, the plant is expected to benefit more than one million residents in Antipolo City and neighbouring Rizal municipalities.

The project includes the construction of major treatment and support facilities such as a raw water tank, mixer-flocculation-clarification tank, dual media filtration system, chlorine contact tank, combined wastewater tank, backwash water system, sludge treatment facilities, chemical and chlorination buildings, potable and service water pump station, administration building with main control room, power substation and fuel storage building.

The Kaysakat Water Treatment Plant represents a significant step in Manila Water’s continuing efforts to strengthen water security for our customers. By developing additional raw water sources and expanding our treatment capacity, we are helping ensure a reliable and sustainable water supply for the East Zone, particularly as climate-related challenges such as El Niño place increasing pressure on Angat Dam.

The project is part of Manila Water’s continuing investments in water infrastructure to secure sufficient supply for the growing needs of customers while building resilience against climate-related challenges, including prolonged dry seasons brought about by strong El Niño events.

With the near completion of the Kaysakat Water Treatment Plant, Manila Water continues to strengthen its water security initiatives by expanding its portfolio of additional raw water sources. The additional 220 MLD of supply will help support 24/7 water service for the company’s 7.9 million customers across the East Zone concession area while enhancing the system’s resilience against climate variability, population growth and increasing water demand. This is on top of other augmentation sources now being utilised coming from Cardona Water Supply System which draws water from the central bay of Laguna Lake and East Bay Phase 1 Water Supply which harnesses water from the eastern flank of the lake.
