99 Ave sanitary trunk rehabilitation

ON THIS PAGE

The 99 Avenue sanitary sewer conveys wastewater from west Edmonton to the Gold Bar Wastewater Treatment Plant. The sewer is approximately 30 metres deep and services approximately 117,000 customers. Inspections have identified the existing trunk varies from fair to very poor condition and requires rehabilitation between 142 Street and 151 Street to ensure it continues to meet the current needs and growth for west Edmonton.

This project has been broken down into two stages: 

  • ​​Stage One: New Sewer Construction - Along 99 Avenue, north on 148 Street and east on 101 Avenue (completed)
  • Stage Two: Rehabilitation of 99 Avenue Sanitary Trunk - Along 99 Avenue, from 142 Street to 151 Street ​​

Project locations

During the first stage of this project, we'll be working at 6 different locations, as noted in the map above. In the summer of 2020, we started work at locations #1 and #2, followed by #3 in the fall.

Please note, all timelines are estimates and may change based on construction progress at the first 2 locations.

What to expect during construction 

To try to understand and reduce the construction impacts to the public, we've met with the Grovenor Community League, the Crestwood Community League, the West Jasper Place Community League, the Candy Cane Lane Committee, St. Andrew's Church and several other organizations that will be impacted by the work.

While we complete this work, you can expect to see activity that's typical to construction, including company/ contractor vehicles and equipment in your neighbourhood. 

  • You can expect to see activity that is typical to construction, including company/ contractor vehicles and equipment. The contractor may use a combination of excavators, loaders, skid steers, cranes, and tandem trucks, as well as other equipment. 
  • The construction area will be fenced/restricted.

We'll also be working on different rehabilitation projects in the same area, during the same time. Find out how this work impacts the 99 Avenue project.

​151 Street South​​ Sanitary Trunk Rehabilitation Project

The 151 Street South Sanitary Trunk Rehabilitation Project is another project planned in the area to rehabilitate the existing trunk line. We have identified several sections of the trunk that need to be rehabilitated.
