MANILA, Philippines — Over 7.4 million Manila Water consumers from Metro Manila’s East Zone and Rizal Province enjoy safe and potable water thanks to the concessionaire’s meticulous regular sampling in 2022.
In September 2022, the Metropolitan Waterworks and Sewerage System (MWSS) confirmed that the water supplied in Metro Manila and Rizal by Manila Water continues to pass the stringent parameters of the Philippine National Standards for Drinking Water (PNSDW).
The water treatment process involved microbiological, physical and chemical examinations of water samples collected from strategically designated Regulatory Sample Points in Manila Water’s source and distribution systems. The sampling covered 99.85% of Manila Water’s overall water distribution.
The Manila Water Laboratory Services (MWLS) also achieved 109.3% compliance, or 5,841 samplings, which exceeded the required particulars set by the PNSDW at 5,344. Water samples were collected from the source all the way to the customer taps in the distribution system, including those at the reservoirs and various pumping stations. MWLS is an accredited Department of Health testing laboratory.
Manila Water Corporate Communications Affairs Group Head Jeric Sevilla said, “The strict and regular testing of water samples from the source to the distribution system will guarantee that our 7.4 million customers get clean and potable water 24/7.” He urges, though, that customers should check the condition of their water connection after the meter to ensure there is no contamination within their internal reticulation system.
Sevilla also underscores that regular check-ups of internal plumbing systems will enable customers to discover leaks after the meter and thus avoid unnecessary spikes in consumption which may lead to excessive billing.
Manila Water has consistently passed the PNSDW as set by the Department of Health and has brought clean drinking water to its customers since it began operating the water supply system in East Zone since 1997.
