The proposed New Centennial Water Source Project (NCWSP) will provide water security, reliability and additional supply for Metro Manila.  It is planned to be site specific, zeroing in on the Kaliwa-Kanan-Agos River Basin as an alternative water source.

The NCWSP will involve the construction of a dam at the Kaliwa River (Laiban Dam), and a smaller dam (Kaliwa Dam) downstream to maximize the water supply, and to ensure short and long term supply for Metro Manila and its adjoining areas.
