• The Putatan 2 plant will provide clean drinking water to almost 6 million people in the metropolitan area of Manila
  • The Plant will have a capacity of 100,000 m3 per day, extendable to 150,000 m3 per day

ACCIONA has won its first project in the Philippines: a $137.5 million contract to design and build the Putatan 2 drinking water plant and to operate it during its first year in service. Building work is expected to be completed in mid-2018.

ACCIONA’s first project in the Philippines is part of a strategy to grow in South East Asia, a market with great potential for infrastructure projects.

The new plant is situated in Muntinlupa, in the south of the metropolitan area of Manila, next to an existing Water Treatment Plant (Putatan 1). The new plant will provide drinking water to almost 6 million people.The Plant will have a capacity of 100,000 m3 per day, extendable to 150,000 m3 per day.

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

One of the main characteristics of the new plant is the advanced treatment of raw water from Laguna de Bay, the biggest lake in the Philippines and the second-biggest inland freshwater lake in South-East Asia, to deliver clean drinking water with a very low carbon footprint. Construction is expected to last 18 months.

The treatment plan for the new plant includes a number of advanced technical processes to ensure clean potable water. These techniques include Dissolved Air Flotation (DAF), Biological Aerated Filter(BAF), Ultrafiltration (UF), Reverse Osmosis (RO) and disinfection in different stages through the oxidation of particular compounds.
