BWPCD owns and operates a municipal wastewater treatment plant that serves the Village of Russell Gardens, portions of the Villages of Thomaston and Great Neck Plaza, and unincorporated areas of the Town of North Hempstead, including University Gardens and western Great Neck. In addition, the District provides wastewater treatment services under contract with Lake Success & 13 properties in the Village of Great Neck Estates. The system includes more than 20 miles of gravity-fed sanitary sewer piping and a treatment facility regulated under NYSDEC SPDES Permit No. NY0026841, designed to treat up to 2 million gallons of wastewater per day before safely discharging treated effluent into Little Neck Bay.
Located near the Queens County–New York City border, the wastewater treatment plant was originally constructed in 1935 with a capacity of 1 MGD and expanded in 1942 and 1950 to meet growing population and development needs. Since the 1940s, BWPCD has consistently invested in modernization efforts to enhance reliability, improve effluent quality, and strengthen environmental performance. These upgrades included Advanced Nitrogen Removal processes, replacement of critical mechanical and electrical systems, and the implementation of flood protection and resilience measures.
