Etangs Aerees Shipshaw Nord Wastewater Treatment Plant, Saguenay, Quebec

Etangs Aerees Shipshaw Nord is a secondary wastewater treatment plant located in the Jonquière borough of Saguenay, Quebec, Canada. It serves a small population of 1,739 residents, reflecting the rural-suburban character of the Shipshaw Nord area. The plant is part of Saguenay's municipal wastewater infrastructure, which manages effluent from the city's various districts. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. Secondary treatment aligns with Canadian federal and provincial regulations under the Wastewater Systems Effluent Regulations (WSER), which require secondary or equivalent treatment for most municipal systems. The plant's discharge volume is 780.80 cubic meters per day, indicating consistent operation. The treated effluent is released into local waterways that drain into the Saguenay River, a major tributary of the St. Lawrence River. The Saguenay River supports diverse aquatic life and is part of the St. Lawrence River ecosystem, which ultimately reaches the Atlantic Ocean. The plant's inland location, more than 10 km from the coast, reduces direct marine impact, but its discharge contributes to the overall water quality of the Saguenay River basin.

The plant discharges into the Saguenay River watershed, which flows into the St. Lawrence River and eventually the Atlantic Ocean. The Saguenay River is a deep fjord-like estuary known for its unique marine and freshwater mixing zone, supporting species such as beluga whales and Atlantic salmon. The plant's secondary treatment helps protect this sensitive downstream environment by reducing organic pollutants and suspended solids before discharge.
