ACCIONA was responsible for the design, construction, operation and maintenance of the Putatán II water treatment plant for one year. It serves an area home to almost 6 million people, with a capacity of 150,000 m³ per day.

The plant is situated in the town of Muntinlupa, at the southernmost tip of the Manila metropolitan area – the country’s capital – also known as Greater Manila, in an area adjacent to the existing water treatment plant (Putatán 1). The plant represents a significant step towards achieving the goal of providing drinking water to an ever-increasing proportion of the population, as – despite the country’s abundance of water resources – many households in the Philippines do not have access to it. The alternatives usually include self-supply (private wells, water drawn from rivers and springs), services from small independent suppliers, or water sold by tanker lorries, amongst others.

A key feature of the 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.
