With the El Niño still expected to persist in the next few months, the National Water Resources Board (NWRB) will be reducing Metro Manila’s domestic water allocation coming from Angat Dam starting June 1.
Based on the Philippine Atmospheric, Geophysical, and Astronomical Services Administration’s (PAGASA) monitoring of major dams in Luzon, the water level at Angat Dam in Bulacan has further declined to 169.88 meters on Tuesday from 170.19 meters last Monday.
It is significantly lower than Angat Dam’s 212- meter normal high water level and 180-meter minimum dam operating level.
NWRB Executive Director Sevillo David Jr. said water allocation for irrigation will remain suspended.
David said there will be a slight adjustment in water allocation for Metro Manila’s domestic needs.
From 48 cubic meters per second (cms) in May, water allocation coming from Angat Dam will be reduced to 46 cms starting June 1, he explained.
The water allocation is split 60-40 to water concessionaires Maynilad and Manila Water, respectively.
David pointed out that the reduced water allocation “will not have any significant impact on Metro Manila households.”
NWRB suspended the allocation of water for the irrigation requirements of farmlands in Bulacan and Pampanga from Angat Dam last May 16 to conserve water and reduce the water level decline in the Angat reservoir.
Angat Dam also supplies about 96 percent of Metro Manila’s domestic water needs. This will be the first time this year that the NWRB will be reducing the allocation of water for domestic supply.
