Canaan Fire District WPCF - Wastewater Treatment Plant in Canaan, Connecticut

Canaan Fire District Water Pollution Control Facility (WPCF) is a municipal wastewater treatment plant located in Canaan, Connecticut, within the Northwest Hills Planning Region. The facility serves a population of approximately 1,400 people, classifying it as a small community system under US EPA guidelines. As a US-based plant, the facility operates under the National Pollutant Discharge Elimination System (NPDES) permit program, which is authorized by the Clean Water Act. The plant discharges treated effluent into the Housatonic River watershed, which flows southward through Connecticut and eventually into Long Island Sound. This water body supports diverse aquatic life and is an important recreational and ecological resource for the region. The facility's location inland and its small service population suggest a lower risk of significant environmental impact.

The Canaan Fire District WPCF discharges into the Housatonic River basin, which drains into Long Island Sound, an ecologically productive estuary. The Housatonic River supports fish populations including trout and salmon, and its watershed provides habitat for various wildlife. The plant's location in a rural, inland area reduces direct coastal nutrient loading, but its discharge contributes to the overall water quality of the river system.
