GLASGO COMMUNITY WTP - Griswold, Connecticut Wastewater Treatment Plant

GLASGO COMMUNITY WTP is a municipal wastewater treatment facility located in the Glasgo section of Griswold, Connecticut, United States. The plant serves a small population of 90 residents and operates as part of the local wastewater infrastructure in the Southeastern Connecticut Planning Region. The plant provides secondary treatment, which is the standard biological treatment process for removing organic matter and suspended solids. With a designed capacity of 37.85 megaliters per year, the facility operates under the regulatory framework of the U.S. Clean Water Act, administered by the Connecticut Department of Energy and Environmental Protection (DEEP) through the National Pollutant Discharge Elimination System (NPDES) permit program. The treated effluent is discharged into local waterways that drain into the Thames River basin, ultimately reaching Long Island Sound. This coastal estuary supports diverse aquatic life and is an important ecological and recreational resource for the region.

The plant's discharge enters the Thames River watershed, which flows into Long Island Sound, a major estuary on the Atlantic coast. The sound provides critical habitat for fish, shellfish, and migratory birds, and is subject to nutrient management efforts to prevent eutrophication. The plant's secondary treatment helps reduce pollutant loads to this sensitive coastal environment.
