The Manila Water on Tuesday announced that it is set to enforce rotational service interruptions for up to 12 hours in areas under its East Zone concession as water level in Angat Dam nears its critical mark.
This follows after the National Water Resources Board (NWRB) said it will reduce allocation to the Metropolitan Waterworks and Sewerage System (MWSS) from 46 cubic meters per second (cms) to 40 cms starting Wednesday, 19 June, until Friday, 21 June.
The NWRB said that its reduced water allocation to MWSS — which allots supply to Manila Water and Maynilad — may be subject to “another adjustment” after Friday if Angat Dam’s 160-meter level is breached by 22 June.
The Manila Water said that it will implement eight to 12-hour rotational service interruptions at night to areas under its jurisdiction and advised its customers to check on their social media accounts for service cutoff schedules.
MWSS Administrator Reynaldo Velasco earlier said water level at Angat Dam may drop to its critical level in two days if there would be no rain and as of Tuesday, the dam’s water level was at 162 meters — only two meters above its critical level of 160 meters.
The Manila Water added that NWRB’s water allocation cutback to MWSS “will affect water supply going to our treatment plants” and noted that they are “constrained to implement a new scheme of rotational water service interruptions for the entire East Zone.”
