The Philippine Metropolitan Waterworks and Sewerage System (MWSS) will launch the tender process for the New Centennial Water Supply Source project in mid September 2014.

The New Centennial Water Supply Source involves the following components: Kaliwa Low Dam with a capacity of 600 million liters per day, a 2,400-MLD water conveyance tunnel, as well as access roads, bridges and drainage system in General Nakar, Quezon.

The project will be under a 25-year build-operate-transfer (BOT) contract.

The project value is estimated at P18.724-billion (US$429 million).

The project is expected to supply an additional 600 million liters a day (MLD) and add to Angat's existing 4,000 MLD capacity. At full completion, the project is targeted to add a capacity of at least 1,800 million liters per day, but this will be achieved in stages.

The New Centennial Water Supply Source project is part of long-running efforts by the government to find and develop a secondary water source to the Angat Dam in Bulacan, which supplies 97 percent of Metro Manila's needs.

To support MWSS on this endeavor, the Public-Private Partnership Center of the Philippines appointed in 2013 RebelGroup in consortium with Allen & Overy, Crisil, PJS Law and Royal Haskoning DHV as the Transaction Advisor for the NCWS Project.
