The Water and Sewerage Authority of Trinidad and Tobago (WASA) is the sole water and sewerage provider in Trinidad and Tobago. It was formed in 1965 by an Act of Parliament to manage the Hollis, Caroni–Arena and Navet dams in Trinidad. In Tobago, WASA maintains the Hillsborough Reservoir along with other freshwater wells to provide municipal drinking water for the country. The purview of the authority extends to the country's sewage treatment plants.
