Parker Storm Retention Basin COCKBURN & CALROSSIE SEWER RELIEF PROJECT INTRODUCTION Cockburn & Calrossie Sewer Relief Project Limits • In River Heights - Fort Garry, changes to the EBBY LEGEND WENTWORTH Cockburn West & Calrossie sewer districts are PROJECT LIMITS SEWER DISTRICTS required to reduce the impacts of combined BOUNDARIES SOUTHEAST JESSIE DISTRICT sewers, namely basement fmooding and H a r the release of diluted wastewater into local GRANT PARK r o w Pembina S Grant Avenue t Highway . Hector Ave. W waterways due to combined sewer overfmows. i l t o n S t COCKBURN . Nathaniel St. • Project includes: WEST DISTRICT . e v A g n i l r a p S - The complete sewer separation in several Taylor Avenue areas including: Cockburn West, Calrossie t e e r t and Southeast Jessie Sewer Districts.

Parker Storm Retention Basin COMBINED SEWER SYSTEM • Combined sewers are a single system of pipes COMBINED SEWER SYSTEM COMBINED SEWER SYSTEM that collect both wastewater from homes, businesses and industries as well as surface runoff from rainstorms and snow melt. • During 'Dry Weather Operation' all combined fmows are treated at one of the City’s three treatment plants. • During 'Heavy Rain Operation' diluted sewage overfmows to local waterways without treatment to protect property, as intended. winnipeg.ca/parkersrb 3
Parker Storm Retention Basin SEPARATE SEWER SYSTEM • Separate sewer systems have two systems of SEPARATE SEWER SYSTEM pipes: - One pipe system carries sewage / wastewater to the wastewater treatment plant. - The second pipe system carries land drainage and surface runoff from rainstorms and snow melt directly to the river. • Separate sewers eliminate the possibility of sewage overfmow to the river system. winnipeg.ca/parkersrb 4
Parker Storm Retention Basin COCKBURN & CALROSSIE SEWER RELIEF PROJECT BENEFITS Overall Benefjts of the Combined Sewer Separation Project include: • Reducing combined sewer overfmows from entering local waterways; • Lowering water treatment costs by preventing rain water and snow melt from going to the treatment plant; • Minimizing the risk of property damage due to basement fmooding; • Helping the City of Winnipeg meet requirements of Environment Act Licence No. 3042 winnipeg.ca/parkersrb 5

Parker Storm Retention Basin PARKER STORM RETENTION BASIN BENEFITS The storm retention basin will be a constructed wetland and will have numerous environmental benefjts: • Walking trails and shaded seating areas; Scatliff+Miller+Murray Photo • Improved water quality of surrounding waterways due to the fjltering out of impurities and pollutants in stormwater; • The establishment of low maintenance native grasses can sequester signifjcant amounts of atmospheric carbon (up to 15 times more compared to conventional sod); Scatliff+Miller+Murray Photo • The planting of native perennials, including milkweed will provide an improved habitat for butterfmies and other pollinator species. The naturalized Parker SRB will result in no net loss of wetlands in the Parker Lands from the South West Rapid Transit and the Cockburn & Calrossie Sewer Relief projects combined, in accordance with environmental licensing Scatliff+Miller+Murray Photo requirements. winnipeg.ca/parkersrb 9
Parker Storm Retention Basin PARKER STORM RETENTION BASIN FEATURES Wetland Planting and Habitat • Wetlands and wetland vegetation slow the fmow of surface water and improve water quality. • Wetland systems can fjlter pollutants and impurities (such as Scatliff+Miller+Murray Photo phosphorus, nitrogen, pesticides and hydrocarbons) from the surface water, resulting in cleaner water being discharged into the rivers. • Wetlands (both natural and constructed) also provide important habitat for many plants and animals. Scatliff+Miller+Murray Photo • Naturalized wetland layout may reduce nesting urban goose population that is often associated with conventional storm water basins, while supporting a richer biodiversity.

Parker Storm Retention Basin PARKER STORM RETENTION BASIN FEATURES Native Upland Grass and Butterfmy Habitat • Upland grass species planted around the SRB will be native to the region and well suited to the local climate and soils. • These plant species develop deep root systems that allow them to Scatliff+Miller+Murray Photo withstand extended periods of drought and thrive without the input of fertilizer or irrigation. • Native perennials, including milkweed, will be planted to attract butterfmies and other pollinator insects. PHOTO COURTESY OF: Scatliff+Miller+Murray Photo http://ereimer.net/20090713/15953_erC720.htm • The habitat will attract pollinator insects, which are critical components of healthy plant communities. Their abundance and diversity can be an indicator of ecosystem health. Scatliff+Miller+Murray Photo winnipeg.ca/parkersrb 11
