Rehabilitation of emergency back-up sewer system

Bridge closure Map_Standard General

Project Overview

The Town of Banff is extending the life expectancy of the emergency backup sewer system that is located under the bed of the Bow River. These two pipes are used only if there’s an issue with the forcemain, which is suspended under the Muskrat Street Pedestrian Bridge. Should the lift station fail, flow is diverted to the pipes under the river to prevent overflow into the river.

The pipes will be lined with high-density polyethylene to prevent corrosion and extend their life expectancy by 50 years. 

A barrier of rocks and stones will also be constructed downstream of the pipes to prevent further erosion and reduce the chance the pipes become uncovered. This layer of new riverbed will provide additional protection from large debris that may be carried downstream. 

Work will take place throughout October and November 2023 to take advantage of both low sanitary flowrates and low water levels.
