MANILA, Philippines — Water service firms Maynilad Water Services Inc. and Manila Water Company Inc. on Thursday set water interruption schedule in some parts of Metro Manila and nearby provinces.

These waters services firm said they would implement daily rotational water service interruptions since the National Water Resources Board announced that it would reduce water allocation from Angat Dam.

It would reduce allocation for concessionaires from 46 cubic meters per second to 40 cms.

As of 6 a.m., Angat Dam’s water level dipped to 160.73 meter mark, less than one meter above the reservoir’s critical level.

It is expected to hit the 160-meter critical level this week due to absence of rains.
