COCKBURN & CALROSSIE SEWER RELIEF PROJECT INTRODUCTION

  • In River Heights - Fort Garry, changes to the

Cockburn West & Calrossie sewer districts are required to reduce the impacts of combined sewers, namely basement fmooding and the release of diluted wastewater into local waterways due to combined sewer overfmows.

  • Project includes:
  • The complete sewer separation in several

areas including: Cockburn West, Calrossie and Southeast Jessie Sewer Districts.

  • The creation of the Parker Storm Retention

Basin (SRB).

COMBINED SEWER SYSTEM

  • Combined sewers are a single system of pipes

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
  • verfmows to local waterways without treatment

to protect property, as intended.

SEPARATE SEWER SYSTEM

  • Separate sewer systems have two systems of

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.

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

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;
  • Improved water quality of surrounding waterways due to the fjltering out
  • f 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);

  • 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 requirements.

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

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.

  • Naturalized wetland layout may reduce nesting urban goose population

that is often associated with conventional storm water basins, while supporting a richer biodiversity.

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

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.

  • The habitat will attract pollinator insects, which are critical components
  • f healthy plant communities. Their abundance and diversity can be an

indicator of ecosystem health.
