West zone concessionaire Maynilad Water Services Inc. announced on Wednesday that it is spending about P2 billion on five mitigation measures to ease the impact of rotational service interruptions in its concession area in the context of the decline in supply in the Angat Dam.
The decreased water level at Angat Dam below its normal operating level of 210 meters and nearing a minimum operating level of 180 meters resulted in a reduction in the allocation of raw water to Maynilad and Manila Water to 40 cubic meters per second (cms) from a regular allocation of 46 cms.
The reduced allocation forced the water concessionaires to interrupt the rotational water service.
This resulted in a supply deficit of 230 million liters per day (mld) for Maynilad.
The Angat water level is still about 21 meters below our target year-end of 210 meters at 188.34 meters, which will allow us to have a good supply during the summer.
Maynilad’s five acts include: raising the ability of Putatan 2 water treatment plant by 50 mld and increasing it to 150 mld by October; optimizing Putatan 1 by an additional 10 mld to make a total of 160 mld; reactivating deep wells with a target capacity of 52 mld by December (14 mld has been achieved to date); minimizing non-revenue water or leakage by 94 mld by February 2020 (40 mld has already been achieved)
The five steps would take a total of 233 mld to ease the deficit of the lower Angat point, the company said.
Of the 233 mld planned, 100 mld has so far been achieved by mitigation measures.
The Angat dam accounts for about 90% of the raw water needs of Metro Manila through the Metropolitan Waterworks and Sewerage System— the government regulatory arm in charge of the Maynilad and Manila Water concessionaires.
Angat also irrigates an estimated 28,000 hectares of farmland in the Bulacan and Pampangan provinces.
