Project History
Construction of the Jamaica WPCP Improvements has two main phases, each consisting of four prime contracts.
Phase I construction began in April 1997 and is scheduled for completion in October 2003.
Phase 2 will have a 5½ year construction period, beginning in January 2003 and ending in June 2006.  The estimated construction cost of Phase 2 is approximately $130 million.
The original Jamaica plant built in the late 1920s consisted of a grit chamber, fine screening chamber, pumping station, and chlorination facilities. 

The pumping station and screening chamber were housed in a 70-foot-diameter caisson commonly referred to as the “Round House.”  These facilities had a capacity for an average flow of approximately 50 mgd.

The plant expansion to a 65-mgd modified aeration facility occurred in the early 1940s.  Plant expansion to 100 mgd with upgrading occurred in 1960-1964.  Further upgrading in 1970 modernized the plant and further improved operations.  The new Sludge Dewatering Building began operation in 1993.  The existing plant wastewater treatment process includes screening, primary settling, activated sludge treatment by step aeration, and chlorination.  Cyclone degritters separate inorganic solids (grit) from the preliminary sludge.  Sludge treatment includes gravity thickening followed by two-stage digestion and centrifuge dewatering.
