NWRB set to reduce allocation to water concessionaires

MANILA, Philippines – The National Water Resources Board (NWRB) is set to cut the water allocation for Metro Manila as the water level at Angat Dam nears critical level.
The NWRB said on Tuesday that the technical working group has proposed to reduce the allocation for the Metropolitan Waterworks and Sewerage System (MWSS) from 46 cubic meters per second (cms) to 40 cms from June 19 to 21.
The NWRB said this is to fine tune the preparation of the Low-Level Outlet (LLO) as a back-up water discharge and to lessen the effect of limited water supply in the coming days before the Angat dam breaches the critical level of 160 meters.
“Ito po yung gusto nating i-manage although limited yung allocation na binibigay natin, this is part of the contingency plan,to manage the limited water supply sa Angat,” said Servillo David, executive director of NWRB.
The agency said that as of 6 a.m. Tuesday, the Angat Dam water level is at 161.78 meters. It is projected to reach the critical level mark in the next three days.
The NWRB said that assuming that the 160-meter level is breached as projected on June 22, the allocation for the MWSS will be adjusted again to give way to the shutting down of the auxiliary unit.
At least 36 cms will be allocated for the MWSS until the dam further declines to 150 meters if there is no significant inflow in the coming days.
The NWRB said that based on the forecast of the Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa), the earliest downpour is expected in the last week of June because a monsoon break, which lessens the chance of rainfall, prevails in the country.
“This will considerably impact the normal delivery of services of both Metro Manila concessionaires, Maynilad and Manila Water and the Bulacan concessionaire. Expect rotational water service interruptions which will be announced the soonest possible time,” the NWRB said.
The agency appeals to the public anew to conserve and use water wisely. (with details from Joan Nano)
MANILA, Philippines — More than one million Manila Water customers will be affected by the rotational water service interruption that the water concessionaire started on Thursday (Feb. 20).
Manila Water said this is due to the low water allocation, as well as its preparation for the dry season.
“So, ineexpect natin na bababa nang husto ang level ng dam. So, this early, kailangan paghandaan natin ‘yon para ‘yong limitadong supply na nakukuha natin sa Angat Dam na siyang nagsu-supply ng 96, 97 percent ng tubig para sa Metro Manila, mas ma-manage natin ng mabuti at nang tayo ay makatawid ngayong summer hanggang sa bago dumating uli ‘yong tag-ulan,” Manila Water Spokesperson Jeric Sevilla said.
In January, the water company started lowering the pressure of the water distributed to households in Metro Manila and Rizal province. This is done in off-peak hours or from 10 in the evening to 6 in the morning.
“While ‘yung interruption na binanggit natin is about 4 to 10 hours. In reality, mas maikli dahil nga madaling araw lang natin gagawin. So, generally, mga 11 to about 3 to 4 in the morning lang ito kung saan hindi nila mararamdaman,” Sevilla said.
He added that the schedule and the affected areas of the water service interruption can be found on the company’s Facebook page.
Manila Water added that the rotational water service interruption will continue as long as the water allocation by the National Water Resources Board is still below normal.
For the past several months, the water allocated to Manila Water is just 42 cubic meters per second —much lower than the normal allocation of 46 cubic meters per second.
As of 8:00 AM on Friday, the water level in Angat dam was at 202.48 meters.
According to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), the rain brought by the Northeast Monsoon or Amihan contributed to the rise of the water level in Angat.
To date, Metro Manila will still have a reduced water allocation.
The NWRB said the board will still have to discuss how much water will be allocated in Metro Manila in the coming months. — (from the report of Asher Cadapan, Jr.) /mbmf
Maynilad has announced that there will be rotational water interruptions from 4 to 8 hours due to the low water level in Angat and Ipo dam.
From 101 meters — which is the maintaining level of Ipo Dam— it dropped to 100.20 meters as of Wednesday (February 5) at 6:00 a.m.
Maynilad Spokesperson Grace Laxamana said it would take time for the water supply to be delivered to customers’ houses due to the low water level in the said dams.
“So kapag mabagal iyong treatment process siyempre mas mabagal rin ang pagpuno ng mga reservoirs natin bago natin mai-deliver sa mga customer natin, (So if the treatment process is slow, it will take time to fill the reservoirs before it can be delivered to our customers),” she said.
Around 80 percent of Maynilad’s customers will experience the rotational water interruption.
Maynilad advises its customers to take note of the rotational service interruption in their area and make sure to conserve water.
“Sinisiguro natin na magkakaroon naman sila araw-araw ng tubig kaya po huwag silang mag-hoard at ipunin lamang iyong kinakailangan nila for the whole day (We are ensuring [customers] will have enough water supply everyday so they should not hoard and just reserve enough water for the whole day),” Laxamana said.—AAC (with reports from Joan Nano)
