Manila Water rotational service interruptions to start Tuesday night

MANILA, Philippines – East zone concessionaire Manila Water Co. announced it will implement rotational water service interruptions beginning Tuesday night.
In a Facebook post, the Manila Water said the entire Metro Manila east zone will experience service interruption for about eight to 12 hours during night time.
The water company said the move is a result of the reduced water allocation of the National Water Resources Board (NWRB) for the Metropolitan Waterworks Sewerage System (MWSS) as the Angat Dam water level continues to decline.
The NWRB earlier said the technical working group has proposed to reduce the allocation from 46 cubic meters per second (cms) to 40 cms from June 19 to 21.
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.
According to Manila Water, the reduced allocation will affect the supply going to its treatment plants.
“We are therefore constrained to implement a new scheme of rotational water service interruptions for the entire East Zone for about 8 to 12 hours during night time,” the company said.
In a separate interview, Manila Water communications planning and tactical development manager Dittie Galang said consumers should brace for longer service disruption because the water allocation is seen to be reduced further if there is no significant inflow in Angat dam in the coming days.
“We are looking at window of 4 to 17 hours water service interruptions per day,” Galang said.
The Manila Water said schedules of water interruptions per area will be released as soon as possible.
“We will continue to provide regular updates regarding the water supply outlook for the East Zone,” it said.
West Zone concessionaire Maynilad Water Services Inc., meanwhile, advised its consumers to store enough water in preparation for longer hours of service interruption.
“Of the 70 percent, 20 percent po dito ‘yung severely affected. Meaning. posibleng hanggang 8 hours lamang sila may tubig sa maghapon at yung remaining 50 percent po ay 9 hours to 16 hours lang yung supply window niya,” said Ronald Padua, head of Maynilad water supply operations.
Meanwhile, MWSS administrator Reynaldo Velasco reminded water concessionaires to strictly follow the water service interruption schedules provided to consumers to avoid facing backlash and penalties.
“Kung ano yung iprinomise nila na delivery, dapat maka-deliver sila on time. Hindi pwede ‘yung ito yung sinabi nila tapos mawawala ang tubig on that time,” said Velasco. (with details from Joan Nano)
Despite the rising water level in Angat Dam, the National Water Resources Board (NWRB) has expressed concern about the possibility of another water crisis next year.
The NWRB said that if Angat Dam fails to reach its normal operating level, Metro Manila might experience another shortage come dry season.
Because of this, Congressman Ruffy Biazon, during the House Committee on Metro Manila Development hearing on Wednesday (August 28), recommended the use of Laguna Lake as a permanent source of domestic water.
This aims to address the shortage of water supply in Metro Manila and its neighboring cities and provinces in case the water level in Angat Dam recedes anew.
“Kasi iilan lang yung nakikinabang doon eh. Pinagkakakitaan yung Laguna Lake hindi para sa paggamit ng ordinaryong mamayan kung hindi sa paggamit ng mga interes ng kumpanya,” Biazon said.
The Laguna Lake Development Authority (LLDA) agreed that this can be done, although they admit that they do not have the funding to conduct dredging in the lake.
They also cited the expense that will be incurred in treating and eliminating the saltwater from Manila Bay that gets combined to the water in the lake.
Add to this is the fast-increasing formation of algae which affects the quality of the water.
“Ang Laguna Lake kaya niyang i-supply ang requirement for domestic water supply as source of domestic water. Ang problema lang is more on the water quality,” said Engr. Emiterio Hernandez of the LLDA.
To date, Maynilad and Manila Water get a small percentage of water supply from Laguna Lake for their customers in Metro Manila, Laguna, Rizal, Cavite, and Bulacan.
Meanwhile, water levels in several dams are continuously increasing due to the rains being experienced in the country.
As of 8:00 a.m. Wednesday, the water level in Angat Dam has reached 181.74 meters.
Ipo Dam water level, on the other hand, has gone up to 11.82 meters; while that of La Mesa Dam went up to 77.18. (from the report of Joan Nano) /mbmf
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 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)
