West Zone concessionaire Maynilad Water Services Inc. has earned nine ISO certifications from the international certifying body TÜV Rheinland, the company announced Thursday.
The certifications cover three major facilities: the Putatan Water Treatment Plant 2 in Muntinlupa, the Parañaque New Water Treatment Plant, and the Novaliches Pumping Station and Reservoir.
Assessments found the facilities compliant with international standards for quality management (ISO 9001:2015), environmental management (ISO 14001:2015), and occupational health and safety (ISO 45001:2018).
“These certifications reflect the discipline and consistency of our teams. They follow global standards not merely for compliance, but to ensure reliable operations and protect the communities we serve,” said Roel Espiritu, Maynilad chief sustainability officer and head of the quality, sustainability and resiliency division.
With the latest recognitions, Putatan Water Treatment Plant 2 now holds five ISO certifications. It previously secured ISO 50001:2018 for energy management and ISO 22301:2019 for business continuity.
The Parañaque New Water Treatment Plant, which produces potable water using wastewater recycling technology, received its first set of ISO certifications. The Novaliches Pumping Station and Reservoir obtained its initial accreditations under Maynilad’s Integrated Management System program.
Maynilad maintains 292 ISO certifications through its partnership with TÜV Rheinland. This is one of the largest certification portfolios in the Philippine water industry.
