Mapleton Drive - finished (treated) water pipe installation begins early November
This week, crews have been working on manholes, drains and vaults at the east end of Mapleton Drive. Next week, a large delivery of the finished (treated) water pipe is expected to arrive. Crews are also planning to conduct some concrete work in the roadway east of the plant (near where the steel plates are) and install drains and other vaults in the right-of-way, where the pipe was installed between the east end of Mapleton Drive and the plant. Please watch out for crews working in these areas – typically there will be a single lane closure during this miscellaneous work, but at times, there will be a full closure and the detour route will be in place. To avoid delays, it is best to use the detour route.
In early November, crews plan to begin laying the finished water pipe near the eastern entrance of the water treatment plant, working west along Mapleton Drive towards Highway 43. Please note, construction priorities and schedules are subject to change.
A scheduled start date for the sewer line relocation near 4020 Mapleton Drive is unknown at this stage. More information will be provided when a date is confirmed.
Road closure and detour route during pipeline construction
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. No pipeline work is planned for this Saturday, October 24 or next Saturday, October 31.
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 or Partnership staff 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.
