Basin C2 Wastewater Treatment Plant, Corner Brook, Newfoundland and Labrador

Basin C2 is a municipal wastewater treatment facility located on Griffin Drive in Corner Brook, Newfoundland and Labrador, Canada. The plant serves a small population of 234 residents and operates under secondary treatment, which is a standard biological process for reducing organic matter and suspended solids. As a Canadian facility, it is subject to the federal Wastewater Systems Effluent Regulations (WSER) under the Fisheries Act, which sets national effluent quality standards for systems serving this population tier. Secondary treatment typically involves biological aeration and settling. The facility discharges 105.00 cubic meters of treated wastewater daily. Given its coastal proximity, the plant must meet stringent effluent limits to protect marine ecosystems, as required by WSER. The treated effluent from Basin C2 ultimately reaches the Gulf of St. Lawrence via the Humber River estuary and the Bay of Islands. This coastal environment supports diverse marine life, including fish stocks and migratory seabirds. The plant's operation is critical for maintaining water quality in the region's ecologically sensitive coastal waters.

Basin C2 discharges into the Humber River system, which flows through Corner Brook into the Bay of Islands and then into the Gulf of St. Lawrence. This coastal area is ecologically important, supporting Atlantic salmon, brook trout, and various seabird populations. The Gulf of St. Lawrence is a major marine ecosystem that sustains fisheries and marine biodiversity. The plant's secondary treatment helps reduce nutrient and pathogen loads, protecting downstream habitats from eutrophication and contamination.
