It doesn't take a rocket scientist to figure out why Manila Water and the MWSS are in trouble.
The Ayala-owned water concessionaire had only 2 million customers when it took over the east zone over 2 decades ago. Today, it has more than 6 million.
Back then, Metro Manila was almost totally dependent on Angat Dam for its water supply and until now, it still is.
Government (via water regulator MWSS, other agencies), past and present, should have prioritized water supply projects since these are essential to human security, but it didn't.
Although Manila Water has done a good job in terms of reducing non-revenue water or wasted water to global standards, it has taken in more customers than it should have. Not really different from a telco accepting more subscribers than its system can handle. Sounds familiar?
Demand outstripping supply plus bad governance and corporate greed is a sure-fire recipe for a crisis.
