West Zone concessionaire Maynilad Water Services Inc. has secured nine new International Organization for Standardization (ISO) certifications covering three of its key facilities, underscoring the company’s continued focus on quality management, environmental protection, and workplace safety.

The certifications were awarded by international certifying body TÜV Rheinland after assessments of Putatan Water Treatment Plant 2 in Muntinlupa, the Parañaque NEW WATER Treatment Plant, and the Novaliches Pumping Station and Reservoir.

The facilities were found compliant with ISO 9001:2015 for Quality Management Systems, ISO 14001:2015 for Environmental Management Systems, and ISO 45001:2018 for Occupational Health and Safety Management Systems.

“These certifications speak to the kind of work our teams do every day. They follow global standards not just for compliance, but because they know it keeps our operations reliable and our communities safe,” said Atty. Roel S. Espiritu, Maynilad’s 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, having previously earned ISO 50001:2018 for Energy Management Systems and ISO 22301:2019 for Business Continuity Management Systems.

The Parañaque NEW WATER Treatment Plant, which produces potable water through advanced wastewater recycling technology, obtained its first set of ISO certifications. Meanwhile, the Novaliches Pumping Station and Reservoir received its initial accreditations under Maynilad’s Integrated Management System program.

Maynilad now maintains a total of 292 ISO certifications under its partnership with TÜV Rheinland, one of the largest certification portfolios in the Philippine water industry, the company said.

Maynilad is the largest private water concessionaire in the Philippines in terms of customer base and serves as the concessionaire of the Metropolitan Waterworks and Sewerage System for the West Zone of the Greater Manila Area, which includes parts of Metro Manila and Cavite.
