In the late 1850s a dam and filtration plant was constructed on the upper reaches of the Maraval River, and until the 1900s it served as Port of Spain's main drinking water supply.[3][4] In 1912 it was transferred to the Port-of-Spain Water Authority. It is currently the property of the Water and Sewerage Authority.[3]
