etangs aeres Saint Come Liniere Wastewater Treatment Plant, Saint-Come-Liniere, Quebec

The etangs aeres Saint Come Liniere is a municipal wastewater treatment plant located in Saint-Come-Liniere, a small community in the Beauce-Sartigan region of Quebec, Canada. The plant serves a population of approximately 1,324 residents, reflecting its role in managing domestic wastewater for this rural area. As a secondary treatment facility, the plant meets the standard level of treatment required for Canadian municipal wastewater systems. Under the federal Wastewater Systems Effluent Regulations (WSER) and Quebec's provincial environmental regulations, secondary treatment is the baseline for most inland plants to protect receiving water bodies. The treated effluent is discharged into local waterways that ultimately drain into the Chaudiere River, a tributary of the St. Lawrence River. This watershed supports diverse aquatic life and is an important ecological corridor in the region. The plant's operations contribute to maintaining water quality in this sensitive freshwater ecosystem.

The plant discharges into the Chaudiere River watershed, which flows northward into the St. Lawrence River near Quebec City. The St. Lawrence River is a major waterway that empties into the Gulf of St. Lawrence, a critical marine environment. The Chaudiere River supports fish species such as brook trout and Atlantic salmon, and its riparian zones provide habitat for migratory birds. The plant's secondary treatment helps reduce nutrient and organic loads, protecting downstream water quality.
