Waterville Sewage Treatment Plant - Cambridge, Nova Scotia | Secondary Treatment Facility

Waterville Sewage Treatment Plant is a municipal facility located on County Home Road in Cambridge, within the Municipality of the County of Kings, Nova Scotia, Canada. It serves a small population of 1,722 residents, reflecting its role in a rural community. The plant is operational and provides secondary treatment, which is a standard level for small agglomerations in Canada. Secondary treatment involves biological processes to reduce organic matter and suspended solids, meeting typical Canadian regulatory requirements for inland wastewater facilities. The plant operates under provincial environmental regulations administered by Nova Scotia Environment, which set effluent quality standards for such facilities. The treated effluent is discharged into a local watercourse that eventually drains into the Bay of Fundy, a globally significant marine ecosystem known for its high tides and rich biodiversity. The plant's location within 50 km of the coast means its discharge contributes to the health of downstream aquatic habitats, including estuaries and coastal zones that support fisheries and migratory birds.

The plant discharges into a local stream that flows into the Cornwallis River, which empties into the Minas Basin of the Bay of Fundy. The Bay of Fundy is a critical habitat for diverse marine life, including the endangered North Atlantic right whale, and supports extensive tidal flats and salt marshes. The plant's secondary treatment helps protect these downstream ecosystems from nutrient pollution and organic loading.
