Our Drainage Neighbourhood Rehabilitation Program focuses on the renewal and replacement of public sanitary and storm sewers to reduce the possibility of sewer back-ups and minimize service disruptions.
Only the public (EPCOR) portion of the drainage system is rehabilitated and renewed through this program. That generally includes services up to the property line.
Drainage rehabilitation for each neighbourhood will take 2 to 3 years to complete and includes the following 3 stages:
We clean both storm and sanitary lines by flushing pressured water through the pipes. Cameras are then placed into the pipes to inspect their condition
– age, material and history of sewer issues. Based on the findings from the inspection, we determine which lines in the neighbourhood require replacement and rehabilitation and
create a design plan to prioritize the work.
During this stage, we replace sewer lines in need of repair that aren't suitable for rehabilitation through relining. Roads, sidewalks and front lawns may need to be excavated to complete these repairs to the drainage system, which includes replacing/repairing manholes and catch basins. When rehabilitation is complete, all affected landscaping, pavement, sidewalks and alleyways will be restored to their original condition.
Just prior to this step, we quickly clean the pipes one more time. Then, damaged pipes are rehabilitated using a trenchless relining method called Cured in Place Pipe, where a sleeve is inserted into broken pipes and then cured, restoring the structure of the existing pipes.
About 80% of rehabilitation work is completed through relining to minimize disruption to pavement and landscaping.

Here is a list of Edmonton neighbourhoods included in our Drainage Neighbourhood Rehabilitation program along with the expected timeline for each stage of work.
Where possible, we coordinated our rehabilitation schedule with the City of Edmonton's Neighbourhood Renewal Program, which will take place after the drainage rehabilitation program is complete. Coordination with the City's renewal program was not possible in neighbourhoods with no City Renewal date indicated.
