Background information on Sewage Management in Antigua and Barbuda


Between 1966 and 2010, several wastewater management studies have been conducted:

  • PAHO Study. Done by the Pan American Health Organization in 1966.
  • Venezuelan Study. It was conducted in 1978 by the Venezuelan government. The service area included 190 acres of commercial area, and 944 acres of residential area. If implemented by 1980, the plan would service a population of 58,000 persons projected for the year 2000.
  • APUA Study. The Antigua Public Utilities Authority (APUA) commissioned this study in 1986. This considered the same service area of the Venezuelan Study.
  • Report on PAHO Feasibility Studies and Proposals for a Sewerage System. This was done in 1992. It would have serviced only 6,070 persons which represents less than 15% of the present population.
  • OECS Study. It was published in 1996 examining the need of wastewater treatment on the countries who are members. It also used the Venezuelan study but increased the service area to 1,976 acres.
  • BiWater Proposal. Submitted in 2005 based on phases of collection and implementation. This is the main report provided by the Department of Environment for the validation of previous studies under our Terms of Reference. Therefore, an additional chapter will be dedicated to a review of this report / proposal in further detail.
