The state government of the Philippines decided in December 2013 to undertake a massive water infrastructure project through a public-private partnership. The New Centennial Water Supply source project aims to secure an alternative water source for Metro Manila by building dams along two major rivers. The project is valued at P 14.2 billion and has already generated major private sector interest according to officials. While the government insists that their value for money analysis proved that P3 was the right way to go, a previous attempt at delivering this project with private investment was very controversial. In 2010 an unsolicited proposal was advanced but it was later rejected because of certain provisions that many felt would raise rates for the public.
