Lagoon Rue Henri Wastewater Treatment Plant, Paroisse de Sainte-Marie, New Brunswick

Lagoon Rue Henri is a municipal wastewater treatment plant located in Paroisse de Sainte-Marie, within the town of Champdoré, Kent County, New Brunswick, Canada. The plant serves a small population of 385 residents and operates under secondary treatment, which is the standard level for communities of this size in the province. The plant's treatment process involves a lagoon system, a common and cost-effective method for small agglomerations in rural Canada. With a discharge volume of 173.00 cubic meters per day, the facility is designed to meet provincial effluent quality standards. As a secondary treatment plant, it removes biodegradable organic matter and suspended solids, providing significant protection to the local environment. The treated effluent is discharged into a receiving water body that ultimately drains into the Northumberland Strait, part of the Gulf of St. Lawrence. This coastal location means the plant's discharge must be carefully managed to protect sensitive marine ecosystems, including fish habitats and migratory bird populations that rely on the estuarine and coastal environments of eastern New Brunswick.

The plant's discharge flows into local waterways that drain into the Northumberland Strait, a shallow arm of the Gulf of St. Lawrence. This coastal zone supports diverse aquatic life, including commercially important fish species and migratory waterfowl. The secondary treatment provided by the plant helps reduce nutrient loading and organic pollution, which is critical for maintaining water quality in the sensitive estuarine and nearshore marine habitats of the region.
