Ferry Road and Riverbend Sewer Separation Project


The City of Winnipeg Water and Waste Department has identified that changes to the existing combined sewer system are required to alleviate basement flooding and reduce the number of combined sewer overflows in the St James area.

The Ferry Road and Riverbend Combined Sewer Relief Works Conceptual Design Report and Study was completed in 2009. The study determined that the current level of service (LOS) for the district's combined sewer capacity is lower than a 5 year return period design storm.

Construction of new land drainage sewers (LDS) in the Ferry Road and Riverbend combined sewer district will convey wet weather runoff freeing up capacity in the existing sewers and improving the LOS. The proposed sewer separation works will be carried out over a number of years within the St. James area requiring 15 Contacts due to the large scale of the work.

Construction of combined sewer overflow and basement flood relief works in the Ferry Road and Riverbend combined sewer district commenced in August 2013 with Contract 1. To date, Contracts 1-4, 5 West, 5 East - Stage 1, 5 East - Stage 2 and 5 East - Stage 3 have been completed at an investment of $24.3 Million. Seven more construction contracts are still required to complete the Ferry Road and Riverbend sewer separation works. Details of the current contracts are as follows:

Contract No. 7
  • Contract start date: Oct 2019
  • Expected completion date: Sep 2020
  • Estimated cost of contract: $6.0 Million
  • Scope of work: A new land drainage trunk sewer will be installed along Douglas Park Road and Assiniboine Avenue from Ferry Road and Riveroaks Drive, along with new land drainage lateral sewers for city streets extending approximately one (1) block north of Assiniboine Avenue, by a trenchless tunnel method to minimize above ground disruption and impact to local residents and the public at large.
  • Note: Contract 6 was delayed due to funding.
