Through collaboration, sewer renewal and bridge rehabilitation occured simultaneously in 2021 and road renewal will take place in 2022. By combining these significant and complex projects, the City realizes substantial cost benefits and efficiencies, as well as the overall duration is reduced.
The sewer relining technique allowed us to renew the pipe without replacement. It is much less invasive and cost effective as all the work happens underground and required little to no work on repairing or repaving roads. A new liner was sealed inside the current sewer main which restored the pipe for another 50 years of use.
The large service area and large pipe means that wastewater services cannot be interrupted for residents. Continuous service was provided using a bypass system which required large pumps running on generators which operated 24 hours a day. Generators are noisy, but they had to run 24 hours a day to provide wastewater services to about 60 per cent of the city’s population or approximately 150,000 residents. Providing continuous wastewater services to residents and businesses was a key focus for this important infrastructure renewal work.
The sewer relining project would have likely taken three construction seasons to complete rather than a single construction season had the City used traditional open-cut methods.
The McCarthy Boulevard bridges were last improved in 2000. This project improved the infrastructure and helped us to prolong the life of the concrete decks, as well as widened existing sidewalks to accommodate multiuse pathway users.
Specific details about the road renewal portion of the project will be provided in early 2022.
- Extended the life of the sewer main that serves 60 per cent of Regina residents by 50 years.
- Strengthened piers to accommodate current traffic loads and increased durability to prolong the life of the concrete deck.
- Upgraded bridge railings and guardrails to improve safety, as well as extended overall service life of the bridge.
- Widened existing 1.5m sidewalks to 3m to accommodate multi-use pathway users.
- 2021 - Sewer system renewal and bridge rehabilitation
- 2022 - Road renewal
- In 2021, the City invested $6.2 million in our sewer system and bridge work.
- In 2022, road renewal will take place with an investment estimated at $1.7 million.
McCarthy Infrastructure Improvement Project
The McCarthy Infrastructure Improvement Project is a two-year major project is taking place along McCarthy Boulevard between Dewdney Avenue and 4th Avenue which combines sewer renewal, bridge rehabilitation and road renewal work.
