Violet Grove’s Constructed Floating Wetlands System with Aeration

By: Brazeau County

The Constructed Floating Wetlands system (CFWs) in Violet Grove, Alberta, aims to revolutionize wastewater treatment in colder climates. With a vision to enhance effluent quality and promote environmental sustainability, this initiative introduces innovative natural treatment processes, leveraging the efficacy of wetlands even in cold climate settings.

Serving the Hamlet of Violet Grove in Brazeau County, the project addresses the need for environmentally friendly wastewater treatment solutions in a community where traditional methods pose potential risks. By deploying CFWs with aeration, the project significantly improves wastewater quality while minimizing environmental impact.

Data from the project showcases remarkable post-winter recovery of plants, with a notable reduction in pollutants, including suspended solids, nitrogen compounds, and biochemical oxygen demand. Additionally, the system’s effectiveness in removing contaminants like phosphorus and E. coli demonstrates its potential for widespread adoption.

Operating under Alberta Environmental and Parks’ guidelines, the project surpasses mandated improvements, contributing surplus renewable energy back to the grid and significantly reducing greenhouse gas emissions. It aligns with Sustainable Development Goal 6 (Clean water and sanitation), ensuring safer water discharge into nearby streams while fostering community growth and sustainability.

As the population of Violet Grove expands, the project provides essential additional wastewater treatment capacity, addressing the community’s growing needs in a sustainable manner.
