Design, construction and operation, and one-year maintenance of the water treatment plant

The new plant is located in the district of Muntinlupa at the southern end of the metropolitan area of Manila, the country's capital, also known as Greater Manila. It adjoins the existing drinking water treatment plant (Putatan 1) and will serve an area with a population of 6 million people with a capacity of 150,000 m3 per day.

The new facility represents a significant step forward towards providing drinking water to an increasingly larger proportion of the population. Many homes in the Philippines do not have access to drinking water despite the abundance of water resources in the country. The alternatives usually involve self-supply (private wells, collection from rivers and springs), small independent water suppliers, or buying water from tankers, etc.

A key feature of the new plant is the advanced treatment of raw water (previously untreated water) from Laguna Lake, the largest lake in the Philippines and the second largest freshwater lake in South-east Asia, to produce clean, pleasant tasting, and healthy water in 18 months, with a small carbon footprint.

Maynilad Water Services Inc. (MWSI), provider of water and wastewater services to the 17 cities and municipalities that make up the western area of Greater Manila, awarded the contract for the plant to a consortium comprising ACCIONA Agua and the local companies, Jardine Electric Control Philippines (JECP) and Frey Fil.

Technology and innovation


reduces biological contamination through the action of microorganisms, while making the treated water clearer by filtering through the solid medium.

Furthermore, in terms of infrastructures, it is worth noting the reduction in space used for biological treatment volume and the removal of the secondary settling.
