At the moment, the Angat dam water level is at 161.78 meters as of 6 o’clock in the morning. It continuously declines despite the PAGASA pronouncement of the onset of rainy season. The dam elevation is projected to reach 160 meters in the next three days.
The TWG is proposing to reduce the allocation to MWSS from 46 cms to 40 cms starting June 19 to 21 to fine tune the preparation of the Low Level Outlet (LLO) as a back-up water discharge before the Angat dam level reaches 160 meters. This is to lessen the significant effect of limited water supply in the coming days.
PAGASA reiterated its forecast that a monsoon break is present in the country which lessens the chance of rainfall in the coming days. Earliest downpour is expected in the last week of June.
On June 22, assuming that the 160-meter level is breached based on the projection, another adjustment will be undertaken in the MWSS allocation because the auxiliary unit will be shut down. However, it is assured that at least 36 cms will be allocated to MWSS until the dam further declines to 150 meters assuming that there is no significant inflow.
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.
We again appeal to the public to conserve water and hope for heavy rains to come in the Angat watershed area.
