Kingston STP - Secondary Wastewater Treatment Plant in Kingston, Nova Scotia

Kingston STP is a municipal wastewater treatment facility located in Kingston, Nova Scotia, Canada. The plant serves a small community of 1,737 residents and operates under secondary treatment standards, which is typical for smaller agglomerations in the region. The plant's treatment process achieves secondary-level purification, removing organic matter and suspended solids before discharge. With a daily flow of 780 m³, the facility meets Canadian federal and provincial regulations for wastewater effluent quality, which are enforced through the Fisheries Act and provincial environmental protection acts. The treated effluent is released into local streams that drain into the Bay of Fundy, a globally significant marine ecosystem known for its high tidal range and rich biodiversity. The plant's inland location (more than 10 km from the coast) reduces direct marine impact, but its discharge still influences the freshwater tributaries that feed into the bay.

The plant discharges into small streams within the Annapolis River watershed, which flows into the Bay of Fundy. The Bay of Fundy is an ecologically sensitive area supporting diverse marine life, including migratory fish and seabirds. The watershed's health depends on effective wastewater treatment to prevent nutrient loading and contamination.
