Currently more than a million people in Manila may have to continue with a six hour water shortage reduction after reserves at the Angat Dam reached a historical low. The dam is Metro Manila’s main source of water.Maynilad, Metro Manila’s west zone water distributor, said that rationing for 1.126 million of its estimated seven million customers will last until Friday, July 23. Also an estimated 3.22 million customers (46%) are likely to be forced to endure scheduled service interruptions that may last upto an hour or more. They are hoping that this will only affect off peak hours when it is unlikely to cause too much disruption. Affected areas include Las Piñas, Caloocan, Malabon, Navotas, Valenzuela, Manila, and Parañaque cities. On July 18th water levels had depleted to reach 157.56m above sea level which is the lowest recorded level for the dam.Raw water produced during the same date reached 1,819.08 million litres of water a day (MLD), one-third lower than the normal level of 2,400 MLD, the company said.
Excuse being given for the lack of water is down to “global warming” and “lack of rainwater” which can only be used as a short term excuse with Manila’s constantly growing population and lack of infrastructure being constructed to support it. The problem can only continue in future years unless drastic measures are taken to increase the supply and delivery methods.
One of the biggest problems the company currently faces though is around 57% of its water is wasted or stolen using figures from June 2010. In 2006 its none revenue water ration was 67% the company’s current NRW ratio may also be affected since supplies to waterless areas are “free”. Another company issue that needs to be quickly resolved and also shows not only are things like this government problems but people stealing makes the problems a lot worse.
There was also two months water thrown away from Angat Dam at the end of last year due to concerns of over spilling which was at risk of repeating affects of storm “Ondoy
In September last year, "Ondoy" brought day-long rainfall that submerged Metro Manila, killing hundreds, displacing thousands, and destroying hundreds of millions of pesos worth of crops and infrastructure.
To avoid "throwing water out" in the future, Maynilad officials sought to have Angat dam controlled by the Metropolitan Waterworks and Sewerage System (MWSS).
The Ayala utility company has offered to assist by offering 36 million Litres of water as they control the East side of Metro Manila’s supply although this is unlikely to solve short-term issues due to the connections being sealed in 1997 when Metro Manila was split into two service areas so opening them back up will be no short term event. The connections are going to be inspected said Maynilad (My question would be how come they don’t already know? Its called maintenance, proactive instead of reactive).
