Design, construction and O&M (1 year)
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 have a capacity of 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 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.
