ACCIONA will increase the capacity of the Putatan 2 potable water plant in the Philippines

• The extension increases the contract value to 112 million euros against the initial 90 million
• Plant capacity will go from 100,000m³ to 150,000m³ per day to supplement the service to around 6 million people

ACCIONA has been awarded the contract to extend the Putatan 2 potable water plant, feed from a brackish source water in the Philippines. The contract for the design, construction, operation and maintenance earlier this year became effective, the plant’s capacity will finally by 150,000m³/d as opposed to the 100,000m³/d initially envisaged.

The initial contract value for the project was around 90 million euros, but after the extension it will rise to 112 million.

The plant will be located in the municipality of Muntinlupa, at the southern end of the metropolitan area of Manila – the country’s capital -, also known as Greater Manila. It will stand on a site adjacent to the existing potable water plant (Putatan 1) and will provide a service to an area including almost 6 million people.The completion of the construction work was planned for 18 months but now will be extended for the additional works to 22 months.

Putatan 2 represented ACCIONA’s first contract in the Philippines and it is a reference point for the company in driving its presence in Southeast Asia, a market with great potential for infrastructure projects.

Maynilad Water Services Inc. (MWSI), the company that manages water supplies and wastewater treatment for the 17 cities and municipalities that form 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 features of the new plant is its advanced treatment process for raw water in Laguna de Bay, the biggest lake in the Philippines and the second biggest inland freshwater lake in Southeast Asia. Within 18 months the process will guarantee clean water that is healthy and has a good taste with a very small carbon footprint associated to it.

This potable water plant is a major step forward towards providing drinking water to an ever larger section of the ever expanding Manila population.

The treatment plan for the new facility includes a number of processes to guarantee potable water, among them Dissolved Air Flotation (DAF), Biological Aerated Filter(BAF), Ultrafiltration (UF), Reverse Osmosis (RO) and disinfection in different stages through the oxidation of particular compounds.
