West Zone concessionaire Maynilad Water Services Inc. said it had spent P410 million for the installation of pressure-regulating valves (PRV) since 2011 to manage water pressure and optimize supply availability for customers.
The company said it has now 1,200 PRVs across its concession area that serve to equalize pressure in the network to provide water to a wider area without putting undue stress on the piping system.
Maynilad added PRVs also automatically lower pressure during off-peak hours to help reduce water losses while also making supply distribution more energy efficient.
“The use of PRVs gives us better control of water flow in the pipelines. We can reduce excessive pressure at night during low-demand hours and redirect that pressure to fill up our reservoirs in preparation for peak demand by daytime,” said Randolph Estrellado, the company’s chief operating officer, in a statement.
He added that to date, around 85 percent of Maynilad’s distribution system is already covered with PRVs and targeted to be fully covered by 2026.
