MANILA, (PIA) – Water utility Maynilad on Monday advised its customers in six Metro Manila cities that they would experience daily water service interruption beginning July 12, 2023, due to a decrease in the water level at Angat Dam.
“Starting July 12, 2023, our customers in portions of Caloocan, Malabon, Manila, Navotas, Quezon City and Valenzuela will have daily water service interruptions as the raw water allocation for MWSS has been brought down to 48 CMS (cubic meters per second) due to the elevation of Angat Dam falling below its minimum operating level of 180 meters,” Maynilad announced on social media.
Portions of these areas will experience water interruption from 7 p.m. to 4 a.m. the following day, it said.
On Monday, July 10, the PAGASA Hydromet Division recorded another drop in the water level at Angat Dam. Based on its 6 a.m. data, the water level decreased from 179.56 meters recorded on Sunday, July 9, to 179.23 meters today. The normal operating level for Angat Dam is 180 meters.
However, Maynilad said that since they are still getting rains over the Ipo watershed,the it is likely that these daily service interruptions may not be immediately felt by July 12.
Moreover, due to water generated from various supply augmentation projects, it said, “the actual duration of these service interruptions may be shorter than projected.”
Maynilad advised affected customers to prepare by storing enough water for their needs during the hours when supply will not be available. They recommened storing water in clean, covered containers.
It also warned to expect some discoloration in the supply upon resumption of the water service. “This is a normal consequence of service interruptions, as the returning supply scours the naturally occurring mineral deposits inside the pipelines.”
“When this happens, let the water flow out briefly until it clears but use the initial flow of water for non-drinking purposes, such as for flushing toilets, to avoid wastage. In case needed, our mobile water tankers are on standby ready to deliver potable water,” it said.
“As we strive to stretch available supplies and generate more water to mitigate the impact of El Niño, we call on all water consumers to do their share in the conservation effort by using water responsibly,” it added.
It can be recalled that Maynilad is being monitored and regulated by the Metropolitan Waterworks and Sewerage System Regulatory Office.
