Cornwallis Waste Water Treatment Plant, Cornwallis Park, Nova Scotia

Cornwallis Waste Water is a municipal wastewater treatment facility located at 30 Billy Bishop Road in Cornwallis Park, Nova Scotia, Canada. The plant serves a small population of approximately 1,072 residents in the Annapolis County area, operating under Canadian federal and provincial environmental regulations. The facility provides secondary treatment, which is the standard biological treatment process required for most Canadian wastewater systems. Secondary treatment typically involves biological degradation of organic matter followed by sedimentation. The plant has a reported discharge volume of 800 cubic meters per day, reflecting its scale for a small community. The treated effluent is discharged into the local watershed, which ultimately drains into the Bay of Fundy, a globally significant marine ecosystem known for extreme tidal ranges and rich biodiversity. The plant's coastal location within 10 km of the Bay of Fundy underscores the importance of effective treatment to protect downstream marine habitats and coastal water quality.

The plant discharges into a local stream system that flows into the Annapolis Basin, part of the Bay of Fundy ecosystem. The Bay of Fundy is a critical habitat for migratory shorebirds, marine mammals, and fish species, including Atlantic salmon. The area's high tidal flushing helps disperse treated effluent, but nutrient loading from coastal communities remains a consideration for water quality management.
