Sewerage Treatment Plants

The NWC operates nearly 100 sewerage (wastewater) treatment plants islandwide. The types of sewerage treatment facilities used in Jamaica include oxidation ditch, activated sludge, waste stabilization pond and primary treatment. Central sewerage systems are located in Kingston and St. Andrew, South-east St. Catherine (Portmore), Montego Bay in St. James, Ocho Rios in St. Ann, and Negril in Westmoreland.

In addition, the NWC has the responsibility for small sewerage systems, which are associated with housing developments in various parts of the country. A packaged sewerage treatment plant is a part of most of these small systems.

The table below provides information on some of the sewerage treatment facilities operated by the NWC.

The NWC has recently completed comprehensive sewerage systems for Ocho Rios (St. Ann) and Negril (Westmoreland) to meet the increasing need for sewerage services in these areas. Similarly, the Montego Bay system in St. James has been upgraded and expanded to meet the long-term requirements for sewerage in that city.

Water Fact

Three-quarters of the Earth's surface is covered with water, yet 98 percent is salt water and not fit for consumption. Less than one percent of all the water on Earth is freshwater available for human consumption.
