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.
