• Water supply cuts start next week


    About 900 barangay (villages)  in Metro Manila and Cavite will have no water from 9 p.m. to 4 a.m. beginning Wednesday next week as utility concessionaire Maynilad Water Services will start implementing supply interruptions on Wednesday next week.

    Maynilad on Friday said the move is meant to ease the pressure off Angat Dam.
    It said the move would affect 56 percent of its customer base.

    The scheduled water interruption may stretch to other areas should the National Water Resources Board (NWRB) lower its water allocation to Maynilad and Manila Water.

    Manila Water customers may expect weaker water pressure from 10 to 11 p.m. to 4 to 5 a.m. by September 21, though they will continue to have an uninterrupted water supply as long as the Ipo Dam is stable.

    Maynilad is plotting a specific supply interruption schedule per area to ensure that affected customers will have water within a limited supply window.

    But during the first week of implementation, these schedules will not yet be adopted as Maynilad strives to limit the service interruption during off-peak hours.

    “At this initial phase of system adjustments, we shall implement the supply interruptions daily from 9 p.m. to 4 a.m. only,” Ronaldo Padua of Maynilad said.

    Padua explained that this off-peak schedule will be gradually extended until, at full implementation, they will adopt the different supply interruption schedules for each area.

    He clarified that although recent rains at the Ipo watershed helped maintain its water elevation and augmented the reduced allocation from Angat Dam, the supply at Ipo Dam is not enough to sustain the company’s water production for the long term.

    Padua said the Ipo Dam is only a diversion control dam and has a small capacity–5.9 million cubic meters  versus Angat Dam’s 850 MCM.

    “So it is barely enough to meet Metro Manila’s water requirement for two days,” he added.
    In preparation for the full implementation of the rotating service interruptions, Maynilad is acquiring additional water tankers and refurbishing its stationary water tanks to serve those areas that are expected to have less than 12 hours of water supply.

    Maynilad is an agent and contractor of the Metropolitan Waterworks and Sewerage System (MWSS) for the West Zone of the Greater Manila Area which comprises parts of Manila, Quezon City, Makati City, Caloocan City, Pasay City, Parañaque City, Las Piñas City, Muntinlupa City, Valenzuela City, Navotas City and Malabon City–all in Metro Manila — and the cities of Cavite, Bacoor and Imus, and the towns of Kawit, Noveleta and Rosario in Cavite.

    1. When the population of Metro Manila was only 30 million people in 1965, we got our water supply from Angat Dam. Now that Metro Manila is home to almost 20 million, our lone source of water is still Angat Dam and no additional reservoirs had been built since then. No wonder we have serious water shortage.

      The do-nothing Aquino should have built the proposed Laiban Dam in Tanay, Rizal. Unfortunately, our President is just all talk, all BS.

    2. when is this going to stop? power interruptions, water interruptions, traffic congestion, crime. are we a failed state?

    3. Interesting to note; that I recall a few years ago reading in the times ..

      That some young engineers had made the comment. That it would not be too difficult to introduce; a method of syphoning off water from the roofs of houses etc ..

      So that this would not only help to reduce flooding; but the water could then be channeled in to the water supply

      Would it not be a good idea; to use money that is still been given out as pork barrel funds.

      To fund a pilot project to see how feasible this idea; would be
