Through collaboration, sewer renewal and bridge rehabilitation will occur simultaneously this year and road renewal will take place in year two. 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 allows us to renew the pipe without replacement. It is much less invasive and cost effective as all the work is happening underground and it requires little to no work on repairing or repaving roads. A new liner is sealed inside the current sewer main which will restore 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 is provided using a bypass system which requires large pumps running on generators to operate 24 hours a day. Generators can be noisy, but they must 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 as we developed the plans 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 will improve the infrastructure and prolong the life of the concrete decks, as well as widen existing sidewalks to accommodate multiuse pathway users.
Specific details about the road renewal project will be provided in 2022.
- Extend the life of the sewer main that serves 60 per cent of Regina residents by 50 years.
- By using the relining technique, we can maintain the flow of sewer network during relining.
- As this pipe runs under Wascana Creek, if we replaced the pipe the traditional way, the Creek would need to be dammed and pumped around the pipe location. By relining, we reduce time for the sewer work and costs.
- Strengthen piers to accommodate current traffic loads and increase durability and prolong life of concrete deck.
- Upgrade bridge railings and guardrails to improve safety, as well as extend overall service life of the bridge.
- Widen existing 1.5m sidewalks to 3m to accommodate multi-use pathway users.
Starting Monday, April 26 to the end of June:
- McCarthy Boulevard will be closed to traffic between Dewdney Avenue and 4th Avenue. Detours will be in place. Watch for signs.
- McCarthy Boulevard between 4th Avenue and Oriole Place will also be closed to southbound traffic. Local access will be maintained with detours.
- Sidewalks will be closed along McCarthy Boulevard between Brunskill Place and 8th Avenue. The multi-use pathway system remains open and users will be able to cross under the McCarthy bridges. Watch for signs.
- 2021 - Sewer system renewal and bridge rehabilitation
- 2022 - Road renewal
- In 2021, the City will invest $3.2 million in our sewer system and $3 million for the 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.
Large bypass pipes along and across McCarthy Avenue at 8th Avenue & Brunskill Place intersections.
Pumps running 24 hrs/day to suck the wastewater out of the sewer and through the bypass pipes to the Pump Station.
McCarthy Trunk Sewer carries wastewater from over 60% of the City’s residents, including downtown.
Pedestrian tunnels will be built to ensure pedestrian safety.
Removal of old concrete barriers and deck.
Lifting new girders into place with a crane.
