Mount Stewart Wastewater Lagoon is a municipal wastewater treatment facility located in Mount Stewart, Prince Edward Island, Canada. The plant serves a small population of 267 residents and operates under secondary treatment standards, which is typical for small communities in the region. As a secondary treatment plant, it uses biological processes to reduce organic matter and suspended solids before discharge. The plant is designed to meet Canadian federal and provincial wastewater regulations, which require effluent quality standards for small systems. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Hillsborough River estuary and then into the Northumberland Strait. This coastal environment supports diverse aquatic life, including fish and shellfish, making proper treatment essential for protecting downstream ecosystems.
Environmental context
The plant discharges into the Hillsborough River system, which flows into the Northumberland Strait, part of the southern Gulf of St. Lawrence. This coastal area supports important fisheries and migratory bird populations. The proximity to the coast (within 10 km) means that treated effluent can influence nearshore water quality, requiring effective secondary treatment to minimize nutrient and pathogen impacts.
