West Zone concessionaire Maynilad Water Services, Inc. (Maynilad) has earned nine ISO certifications from international certifying body TÜV Rheinland, underscoring the company’s continued commitment to quality, environmental stewardship, and workplace safety across its operations.
The certifications cover three major facilities—Putatan Water Treatment Plant 2 in Muntinlupa, Parañaque NEW WATER Treatment Plant, and the Novaliches Pumping Station and Reservoir—which were assessed and found compliant with international standards for Quality Management Systems (ISO 9001:2015), Environmental Management Systems (ISO 14001:2015), and Occupational Health and Safety Management Systems (ISO 45001:2018).
“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 Quality, Sustainability and Resiliency Division.
With these latest recognitions, Putatan Water Treatment Plant 2 now holds five ISO certifications, having previously earned ISO 50001:2018 (Energy Management System) and ISO 22301:2019 (Business Continuity Management System). The Parañaque NEW WATER Treatment Plant, which produces high-quality potable water through advanced wastewater recycling technology, obtained its first set of ISO certifications, while the Novaliches Pump Station and Reservoir received its initial accreditations under Maynilad’s Integrated Management System (IMS) 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—affirming the company’s sustained adherence to globally recognized operational, environmental, and safety standards.
