Water and sewerage are under the purview of the Water and Sewerage Authority of Trinidad and Tobago (WaSA). Much of the city's water supply comes from the Caroni Arena Dam located in the Arena Forest Reserve near Brazil Village. The Caroni Arena Dam supplies the Caroni Water Treatment Plant located opposite the Piarco International Airport Southern Terminal.  This Caroni Water Treatment Plant was upgraded in 2000 to a total daily production of 75 m.g.d.
