The City of Edmonton owns and operates over 5,400 km of sanitary, storm and combined sewers, and about 332,000 sanitary service connections. The average age of the pipes is 42 years with an expected asset life of 100 years. Due to aging and deterioration of drainage infrastructure, the City may be vulnerable to unexpected failures that disrupt not only sewer service to homeowners but above ground activities as well.
This program provides a long-term strategy to systematically address the needs of drainage infrastructure. The work is done in coordination with the neighbourhood renewal program and other utility companies, to reduce inconvenience and service disruption.
This program covers the following areas:
- Drainage Neighbourhood Renewal Coordination
The contruction includes mainline sewer replacements, manhole repairs, and service connections renewal. The priority of the work is based on the results of closed circuit TV inspection on the physical condition of the drainage assets.
- Sewer Upgrading
This work addresses pipe capacity issues by upgrading the pipes to a larger size. It improves the service level of the drainage sewer systems in all neighbourhoods in the City that were built prior to 1989. To date, 87 neighbourhoods have been assessed and 66 neighbourhoods have concept designs completed. The remaining neighbourhoods will be evaluated in the upcoming years.
- Service Connection Renewal
This long-term work includes program development followed by design and construction works for the next 2-3 years. A strategy will be developed to work with homeowners and to prioritize locations for renewal.
- proactively renews and upgrades the drainage system
- the right type of drainage asset is renewed at the right time to prevent unexpected failures
