Westmount _ Coxheath C3 Wastewater Treatment Plant, Westmount, Nova Scotia

Westmount _ Coxheath C3 is a municipal wastewater treatment plant located in Westmount, part of the Cape Breton Regional Municipality in Nova Scotia, Canada. The plant serves a population of approximately 16,397 people, placing it in the medium agglomeration category for Canadian wastewater infrastructure. As a Canadian facility, the plant operates under provincial and federal regulations, including the Canada Water Act and the Fisheries Act, which govern effluent quality and environmental protection. Plants of this scale in Nova Scotia typically employ secondary treatment or equivalent to meet regulatory standards. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Atlantic Ocean via the Bras d'Or Lake or Sydney Harbour. This coastal environment supports diverse marine life and is ecologically sensitive, requiring careful management of nutrient and contaminant loads to protect water quality and aquatic habitats.

The plant discharges into the watershed of Cape Breton Island, which flows into the Bras d'Or Lake, a large estuarine system connected to the Atlantic Ocean. This coastal ecosystem supports diverse aquatic life, including fish, shellfish, and migratory birds, and is sensitive to nutrient enrichment and pollution from wastewater discharges.
