Lumsden Cat Harbour Sewage Treatment Plant - Secondary Treatment in Lumsden, Newfoundland

The Lumsden Cat Harbour Sewage Treatment plant is a municipal facility located on Highway 330 in Lumsden, Newfoundland and Labrador, Canada. It serves a small population of 445 residents, reflecting the rural character of the community. The plant is classified as operational and provides secondary treatment, which is appropriate for its scale. As a secondary treatment facility, the plant uses biological processes to reduce organic matter and suspended solids before discharge. Under Canadian federal and provincial regulations, such facilities are required to meet effluent quality standards set by Environment Canada and the Newfoundland and Labrador Department of Environment and Climate Change. The plant is situated within 10 kilometers of the Atlantic coast, making its discharge potentially influential on coastal water quality. Treated effluent likely enters a local watercourse that drains into the Atlantic Ocean. The surrounding marine environment supports diverse aquatic life, including fish stocks and seabird populations, and the plant's secondary treatment helps mitigate nutrient and pathogen loading to these sensitive coastal waters.

The plant discharges into a local watercourse that flows into the Atlantic Ocean near Lumsden, Newfoundland. The coastal waters in this region are part of the Labrador Current ecosystem, supporting cold-water fish species such as Atlantic cod and capelin, as well as seabird colonies. Secondary treatment reduces organic pollutants and pathogens, helping to protect the marine environment from eutrophication and contamination.
