Project Justification

The installation of a dualling system for the Caroni South Trunk Main will increase the reliability and efficiency of the supply of potable water to a population of approximately 310,000 persons in the areas of South and Central Trinidad and the Point Lisas Industrial Estate. It will reduce the pressure limit at the Caroni Water Treatment Plant on the South Transmission Line, in turn reducing shut-down time.

The minimising of both cost and time spent on repairs of bursts and leaks can also be expected. In conclusion the Water and Sewerage Authority of Trinidad and Tobago's mandate of achieving a minimal of a 24/2 level of potable water supply to customers, while maintaining service levels exceeding that target, can be met with the implementation of the dualling of the Caroni South Trunk Main.

The following benefits to be achieved further justify this project:

1.  Redundancy in the South Transmission System

2.  Increased capacity of the South Transmission System

3.  Proposed main forms part of the National Transmission Grid

4.  Improved pressure to Savonetta and San Fernando Booster

5.  Use of California and San Fernando Tanks (45 Ml Capacity)
