THE NATIONAL Water Resources Board (NWRB) on Wednesday said it will maintain its water allocation to Metropolitan Waterworks and Sewerage (MWSS) at 36 cubic meters per second (CMS) to help in first improving the water level in Angat Dam.
“Ang (The) technical working group ay nag-meeting ngayong araw (had a meeting today) and reviewing ‘yung (the) current situation for the past weeks, including the PAGASA projection… walang masyadong pag-ulan ang darating (there will be not much rain coming) starting today until next week, so we decided to maintain the allocation of 36 cubic meter per second,” NWRB Executive Director Sevillo D. David, Jr. said in a briefing after the TWG meeting.
The NWRB reduced water allocation during this month from 46 CMS to 40 CMS, and further to 36 CMS as the Angat Dam water level dropped below the 160-meter critical level.
As of 6 a.m. Wednesday, the water level in Angat Dam was at 161.08 meters, based on the monitoring of the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).
Angat’s minimum operating water level is 180 meters.
Based on PAGASA’s forecast, up to three typhoons are expected towards the end of July.
MWSS Administrator Reynaldo V. Velsaco, for his part, said water interruptions will continue.
He also said that water supply at the La Mesa dam will not be used since Angat is still able to supply the 36 CMS.
“Gusto namin ang (We want that) La Mesa Dam will just be a reserve… paakyat na eh so hindi na natin kailangang galawin ‘yan (It’s [water level is] already going up so we do not need to use it anymore). In fact, we wanted make La Mesa to go as high as about 78 (meters) para malaking suporta ‘yan (so it will be a big support),” he explained.
Data from PAGASA show La Mesa dam’s water level was at 72.35 meters as of 6 a.m. on Wednesday. — Vincent Mariel P. Galang
