This data was created for Federal and Provincial Government reporting by the City of Winnipeg’s Water and Waste Department to track the combined sewer overflow (CSO) volume and days effluent is deposited. All volumes are noted in m³. Volumes are estimated based on modeled data and further validated by instrumented data for the monitored overflow points. An amount of 1 indicates an unknown volume of effluent deposited from a monitored overflow point. Refer to the attachments for further information on each overflow point's location, instrumentation, and maintenance
