Saint Jean de la Lande Wastewater Treatment Plant - Saint-Côme–Linière, Québec

Saint Jean de la Lande is a wastewater treatment plant located in Saint-Côme-Linière, within the Beauce-Sartigan region of Québec, Canada. It serves a small population of approximately 390 residents, reflecting its role as a community-scale facility in a rural setting. The plant is operated as part of the municipal wastewater infrastructure for the area. The plant provides secondary treatment, which is a standard biological process that removes organic matter and suspended solids. For a facility of this size, secondary treatment meets the typical regulatory requirements under Canadian provincial guidelines, which aim to protect water quality in receiving environments. The plant discharges an average of 175 cubic meters of treated wastewater per day. The treated effluent is released into local streams that eventually drain into the Chaudière River, a major tributary of the St. Lawrence River. This watershed supports diverse aquatic life and is important for regional biodiversity. The plant's operation helps maintain water quality in this sensitive river system, contributing to the ecological health of the St. Lawrence River basin.

The plant discharges into local watercourses that flow into the Chaudière River, which ultimately reaches the St. Lawrence River. The Chaudière River watershed supports a variety of fish species and provides habitat for migratory birds. The St. Lawrence River is a major ecological corridor in North America, and maintaining water quality in its tributaries is critical for the health of the entire ecosystem.
