At $340 million, the Woodward Wastewater Treatment Plant upgrades represent the largest investment within the City of Hamilton’s Clean Water Program. The upgrade project is a multi-phase, multi-year process that includes a number of sub-projects, each of which has its own specification and timelines. Learn more about what work is currently taking place as part of this project.

Sub-Project Benefits Supporting Resources Current Status

Tertiary Treatment Upgrades, New Chlorine Contact Tank and Improvements to Red Hill Creek

Improved Effluent Quality: Addition of a tertiary treatment process to allow the Woodward Wastewater Treatment Plant to meet stringent Hamilton Harbour Remedial Action Plan targets.

Maximizes Plant Hydraulics: Dedicated discharge location into Red Hill Creek required for tertiary treated effluent, and dedicates existing outfall for increased treatment of wet-weather flows.

Red Hill Creek: Improvements, including widening, of Red Hill Creek between the new and existing outfall to convey the new tertiary treated effluent.

Main Wastewater Pumping Station Upgrades

Increased Capacity: Meet future wet-weather capacity needs of 1700 MLD.

Improved Conveyance: Larger and deeper wet well to mitigate system flooding, provide increased system storage and reduce solids buildup during dry weather flows.

Improved Maintenance: Split wet well design allowing for half of the wet well to be taken off-line for maintenance, while pumping station remains in operation.

Construction of new plant entrance complete as of October 2017, along with relocation of the City’s site offices.

Excavation of the Main Pumping Station has been completed.  The structure below ground has begun with initial concrete pours of the dry well, wet well and wet well divider having taken place. The permanent concrete liner for the tunnel connecting the influent pipe to the pump station has been completed, and the headworks bypass chambers were completely constructed and leak tested.

Electrical and Chlorination System Upgrades

Replace Aging Assets: Reduce risk by replacing critical assets at the end of their useful life.

Increased Standby Power: Provide sufficient standby power to all essential loads.

Energy Efficiencies: Maximize energy efficiencies wherever possible.

Construction began October 10, 2017.

Foundations for the Electrical Power Centre building are nearly complete and construction of masonry and steel for the structure continues. Underground utilities and duct bank installations continue to moving forward. Electrical conduit rough-in installations continue while fabrication of a number of electrical transformers has been completed.

The new Chlorine Evaporator and Chlorinator for the Wastewater Treatment Plant were installed and associated pipework installation continues.
