Angat Dam - Manila's main water reservoir falls below critical low, Philippines

The water level in Angat Dam, the main water supply for Metro Manila fell below the critically low level of 160 m (524.9 feet) on July 11, 2019 and stood at 159.91 m (524.6 feet) as of 08:00 LT.

Manila Water said yesterday it has narrowed its supply gap with increased production in its Cardona Water Treatment Plant in Rizal, the rehabilitation of existing deep wells and construction of new wells across the East Zone, and the efficient reduction of its systems loss or Non-Revenue Water (NRW) to 7.5%.

As of July 7, 2019, the Cardona WTP is already producing up to 63 million liters per day (MLD) and the total yield from all operational deep wells has reached 58 MLD.

Moreover, from an average of 12% NRW from late last year to early this year, it has been reduced to 7.5% in June 2019. This translated to almost 70 MLD volume of water recovered and returned to the system for distribution to customers.

"While we have increased our efficiencies and the technical solutions we have put in place are ensuring we are able to distribute the still-limited supply as equitably as we can, we cannot rest and let our guard down," said Manila Water Chief Operating Officer Abelardo P. Basilio.

"The water supply situation remains volatile and continues to change day to day as Angat, Ipo and La Mesa Dams remain in sub-ideal levels. We are keeping to our commitment of working towards 24/7 supply at 7 psi pressure, or reaching only up to the ground floor, for all customers."

Angat dam fulfills 97 percent Metro Manila's everyday requirement. 

It supplies irrigation to 20 000 hectares (49 420 acres) of farmland in Bulacan. It also provides 2 000 hectares (4 942 acres) of Pampanga's farmlands in Candaba and borderlands of San Luis and San Ana.
