MANILA – The National Water Resources Board (NWRB) announced the daily water allocation for the Metropolitan Waterworks and Sewerage System (MWSS) will be maintained although the agency expects water level in Angat Dam to breach current record low this weekend.
“NWRB decided to maintain the current allocation of 36 cubic meters per second (cms) for the rest of June,” NWRB Executive Director Sevillo David Jr. said in a press briefing on Wednesday.
David told reporters they expect the dam’s water level to breach its lowest level of 157.57 meters recorded in July 2010.
“If the situation continues, we are expecting the level of the Angat Dam to breach the lowest recorded of 157.57 [meters] by end of this week, most likely Saturday,” he said.
“It is continuously going down without any significant rainfall flowing into the Angat watershed,” he added.
As of Thursday, Angat Dam, the primary source of water in Metro Manila and nearby provinces, has dropped to 158.15 meters amid the monsoon rains.
The Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) said the watershed received only 118 millimeters of rainfall from June 1 to 25.
Pagasa chief of climate monitoring and prediction section Analiza Solis saying it comprises only 36 percent of the normal rainfall of 332.4 millimeters the dam should receive.
Despite monsoon rains, David said they will closely monitor rainfall developments in the dam.
Earlier, the NWRB reduced the water allocation for the MWSS to 36 cms from 40 cms. The regular allocation to the MWSS is 46 cms, split between Manila Water Co. Inc. and Maynilad Water Services Inc.
Both Manila Water and Maynilad have been implementing rotational water service interruptions in order to maximize the limited supply and ensure that all customers will have some water supply daily. (JL/ LON)
