• Founded in 1915, the PWWPCD is one of the oldest water pollution control districts on Long Island.
  • The PWWPCD serves more than 28,000 residents and businesses in the greater Port Washington area, including the Village of Port Washington North, as well as portions of the Villages of Flower Hill and Baxter Estates. In addition, under the terms of an outside contract, the District treats the sewage collected by the Village of Manorhaven which the village conveys to the District via their sewage pumping station.
  • Sewage is transported to the wastewater treatment plant (WWTP) through 75 miles of gravity sanitary sewers and 17 sewage pump stations. 
  • The PWWPCD is an activated sludge wastewater treatment plant designed for a flow of 4.0 million gallons per day (MGD).
  • The PWWPCD Board is comprised of three Commissioners who oversee a staff of approximately 20 employees. The Commissioners are local residents elected to three-year terms. One commissioner is elected each year, on the second Tuesday of December.
  • For over 100 years, the PWWPCD has served the community. For a trip down memory lane, view our photo gallery.
