Together with the International Institute for Sustainable Development (IISD), we are recommending an interim retrofit to Winnipeg’s largest sewage treatment plant. A chemical system could be implemented quickly and at low cost to significantly reduce the facility’s phosphorus contribution to Lake Winnipeg.

Presenting to the Standing Committee on Legislative Affairs on proposed amendments to Manitoba’s Environment Act, we recommended that no changes be made to legislation governing Manitoba’s hog industry until water-quality data is available to determine if current manure management practices are effective at keeping phosphorus out of our lakes and rivers.

Our submission recommends that no changes to regulation or associated legislation dictating where, when and how livestock manure can be used as an agricultural fertilizer be made without first providing evidence that increased manure application will not result in a corresponding increase in phosphorus loading to Lake Winnipeg.
