As of 6:00 a.m. on Thursday (July 11), the water level in Angat Dam has dipped lower than the critical level at 159.93 meters.

This is lower compared to the 160.30 meters recorded on Wednesday (July 10).

The National Water Resources Board (NWRB) reduced the amount of  water allocated to Metropolitan Waterworks and Sewerage System (MWSS) from 46 cubic meters per second (cms) to 36 cms.

Metro water allocation to increase on Sept. 1 as Angat dam level improves – NWRB

MANILA, Philippines – The allocation for Metro Manila water concessionaires will slightly increase next month as rains brought about by recent weather disturbances continue to boost the water level at Angat dam, the National Water Resources Board (NWRB) said Monday.

NWRB director Servillo David Jr. said the water of Angat dam is already above the minimum operating level of 180 meters and is expected to rise further based on the rainfall projections of the Philippine Atmospheric, Geophysical and Astronomical Service Administration (PAGASA).

“With the current level of Angat which is already above 180 meters and expected to rise further with incoming weather disturbances and Pagasa projections of near-normal rainfall for September, there will be an adjustment in allocation for water supply and irrigation starting September 1,” he said in a message sent to reporters.

David said the current water supply allocation of 36 cubic meters per second (cms) will be increased to 40 cms for the Metropolitan Waterworks and Sewerage System (MWSS). Allocation for irrigation will also go up next month.

“For water supply from 36 cms to 40 cms. There will be allocation for irrigation also up to 30 cms,” he said.

The NWRB reduced the water allocation for Metro Manila to 36 cms from 40 cms when Angat dam breached the critical level of 160 meters in June.

The allocation was a huge slash from the average allocation of 48 cms on normal days.

The reduced water allocation resulted in rotational service interruption in Metro Manila and nearby provinces in the previous month.

PAGASA earlier said it may take until September before Angat dam level returns to normal.

PAGASA Hydrologist Shiela Schneider said the projection was based on dam monitoring in previous years.

“Kasi nandito na tayo sa tag-ulan, may mga bagyo at may mag inexpect pa tayo na bagyong dadating so inaasahan, based from the historical naman natin na mga data, nakikita natin during these months talaga tumataas ang elevation ng Angat dam” she said.

Aside from Angat dam, water level at other dams in the country, including La Mesa, Ambuklao and Ipo, were also reported to have improved. (RRD with details from Correspondent Joan Nano)

PAGASA declares end of El Niño

MANILA, Philippines – State weather service PAGASA has declared the end of weak El Niño which has started in the last quarter of 2018.

This means that the temperature in the Pacific Ocean has returned to normal and will remain so until the end of 2019.

During the past three to five months, areas of Oriental Mindoro and Sultan Kudarat experienced less rainfall.

But this August, PAGASA expects normal rainfall level in areas of Calabarzon, MIMAROPA, Bicol Region, Metro Manila, most parts of Eastern Visayas, and the provinces of Nueva Viscaya, Quirino, Bataan, Aurora, Agusan Del Norte, and Surigao Del Norte.

The El Niño has incurred P7.963-B worth of damage in agriculture across the country, according to data from the National Disaster Risk Reduction and Management Council (NDRRMC) in JUNE 27, 2019.

This is apart from other problems such as the water crisis that hit Metro Manila when the level of water reserve in Angat Dam dipped below the minimum operating level of 180 meters.

For now, the dam’s supply is gradually recovering as it hit 177.12 meters at 6:00 a.m. today (August 16).

With this development, the National Water Resources Board (NWRB) may soon increase water allocation in Metro Manila to 40 cubic meters per second from the current 36 cubic meters per second, according to the agency’s Executive Director Sevillo David. – MNP (with details from Rey Pelayo)
