Satellite City – Trunk Sewer Rehabilitation
The Satellite City sanitary trunk sewer is a critical sewage pipeline that services a large portion of the East Hamilton/Stoney Creek Mountain. Constructed in 1974 this 900mm, 8m deep, reinforced concrete pipe extends from Mud Street West, through Hamilton Conservation Authority lands (Felker’s Falls), the Niagara Escarpment and Bruce Trail before reaching Quigley Rd.
Due to high levels of H2S corrosion (Hydrogen Sulphide – a commonly occurring gas in sanitary sewers) accelerated degradation of the pipe continues to occur, significantly reducing its expected life span.
With the urgent need to stop or slow damage to the pipe and consideration for the sensitive surrounding areas, the City of Hamilton has expedited a minimal impact, sewer rehabilitation project slated to be substantially completed by Dec 16, 2022 with final restoration taking place in Spring of 2023.
In order to complete this work:
- Construction of temporary access roads and tree trimming/removal within the alignment:
- From Thornbury Court – North approx. 500m towards escarpment edge (Felker’s Falls)
- From 500 Quigley Rd – South approx. 60m towards escarpment base (Felker’s Falls)
- From Quigley Rd – North approx. 115m along Davis Creek
- From Greenhill Ave – South approx. 90m along Davis Creek
- Limited excavations to widen existing maintenance holes
- Periodic restrictions/closures of paths and trails during construction process
- Night work and construction noise outside of typical working hours
Location: Stoney Creek Mountain (Mud St W to Quigley Rd) Wards 5 & 9
Status: Sewer Rehabilitation in progress
How Project is Implemented
- Phase 1: Tree cutting during the permitted window (Oct 1 to March 31) within the limits of the proposed temporary access road - Winter 2021/2022
- Phase 2: Grading of land, excavation and widening of existing maintenance holes, installation of temporary access road and required tree protection and fencing - Summer 2022
- Phase 3: Installation of bypass pumping (temporary sewage conveyance system) and rehabilitation of sewers and maintenance holes - Fall/Winter 2022
- Phase 4: Restoration of site - Spring/Summer 2023
