Project Background

The Water and Sewerage Authority (WASA) is the largest public utility in the country. It serves over ninety percent (90%) of the population with pipe borne water through private house connections and standpipes. Since its establishment in 1965, water production has increased from 223,000 cubic metres to 650,000 cubic metres in 1990. With respect to wastewater 30% - 40% of the population are served by a central sewerage collection and treatment system. Another 40% of the population are served by cesspit-tank soil-absorption field systems. Those remaining are served by pit latrines.

WASA has been mandated to provide customers with a 24/2 water supply as a minimum, while maintaining service levels currently exceeding this target.  The Caroni South Trunk Main currently serves Central and South Trinidad. It serves a population of approximately 310,000 persons and Point Lisas Industrial Estate. The pipeline is aged approximately thirty (30) years and comprises of ductile iron which is encased in polythene. The Caroni South Trunk Main has dimensions of 1350mm from Caroni Water Treatment Plant to Savonetta Booster and 1050mm from Savonetta Booster to San Fernando. The pipeline is in a significantly good condition for its age.

In order to improve the efficiency and reliability of the supply of potable water to Central and South Trinidad there is a need for a level of support for the Caroni South Trunk Main. This support is in the form of a dualling system, where a support network of pipeline will be laid parallel to the existing.
