Mapleton Drive - raw water pipe now installed to the water treatment plant!

The raw (untreated) water pipe has now been installed to the water treatment plant. Over the next few weeks, crews will install drains and vaults, place temporary trench patches, and conduct miscellaneous cleanup work where the pipe was installed between the east end of Mapleton Drive and the treatment plant. They may also begin testing the newly-installed raw water pipe. Please watch out for crews working in these areas.

Once this is complete, crews plan to begin laying the finished (treated) water pipe from the water treatment plant west along Mapleton Drive towards Hwy. 43, however, construction priorities and schedules are subject to change.

A scheduled start date for the sewer line relocation is unknown at this stage. More information will be provided when a date is confirmed.

Road closure and detour route

During work hours, a detour is in place and no through traffic is allowed in the active work zone on Mapleton Drive. Please follow the detour signage directing traffic around the closure area.

The road is closed to through traffic at the active work zone as it moves along Mapleton Drive. Residents located east of the active work zone will need to use the detour route on Nixon Avenue, Elmran Drive and Cedaroak Drive during work hours (refer to detour map link above). Residents located west of the active work zone can use Mapleton Drive between their home and Highway 43 during work hours.

For more information about road closures and detours, refer to the guidelines.

Work hours and what to expect

Work hours on Mapleton Drive are Monday to Friday, 7 a.m. - 7 p.m. and Saturdays, 9 a.m. - 5 p.m.

Neighbors can expect to see and hear excavators, generators, loaders, saw-cutters, compressors, pipe, steel plates, gravel and dump trucks in the work area, staging areas and right-of-way on Mapleton Drive. During work hours, there will be an increase in noise, truck traffic and vibration, depending on neighbors’ locations.

Crew members will notify affected residents who may have their driveways blocked during pipeline construction work hours—typically one to three days in advance—to explain which driveways will be impacted and coordinate parking.
