Description
The City of Portage la Prairie will evaluate potential treatment strategies for its wastewater effluent to reduce the nutrient loading it currently contributes to Lake Winnipeg. The project team will assess several pre-treatment technologies, especially those related to the removal of phosphorous and management of biosolids, and develop a short list of preferred systems. The technological and financial analyses of these technologies, based upon actual flow scenarios, will lead to an implementation strategy for the chosen system. The resulting capital project will reduce nitrogen levels by 71 per cent and phosphorous levels by 95 per cent. This will reduce algal blooms and water pollution in Lake Winnipeg, which currently have a negative impact on fisheries, tourism and recreation. Biological nutrient removal will also produce biosolids that could be used to offset demand for manufactured fertilizers, and biogas that could be used for heating or electricity production.
