North Hempstead T Belgrave Wastewater Treatment Plant, Queens, New York City

North Hempstead T Belgrave is a wastewater treatment plant located in the Belgrave Water Pollution Control District in Queens, New York City, New York. It serves a population of approximately 12,377 residents as part of the city's extensive wastewater infrastructure. The plant operates under the regulatory framework of the US Clean Water Act, which requires secondary treatment for municipal wastewater. As a facility serving a medium-sized community, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the New York State Department of Environmental Conservation, ensuring compliance with water quality standards. The treated effluent from the plant is discharged into the local water system, which ultimately drains into the Long Island Sound. This water body supports diverse aquatic life and is an important ecological and recreational resource for the region. The plant plays a key role in protecting the sound's water quality and the broader New York Harbor ecosystem.

The plant discharges into the local watershed that flows into the East River and then into Long Island Sound, a vital estuary supporting diverse marine life, including fish, shellfish, and migratory birds. The sound is ecologically sensitive due to its role as a nursery for many species and its proximity to the densely populated New York metropolitan area.
