Woodward Upgrades Sub-Projects
Woodward Wastewater
Treatment Plant Upgrades
At $340 million, the Woodward Wastewater Treatment Plant upgrades represent the largest investment within the City of Hamilton’s Clean Harbour 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.
In 2008, the City completed the Woodward Avenue WWTP Service Area Environmental Study Report to determine a plan for upgrades to the Woodward WWTP to manage wet weather flows, provide treatment capacity, and meet treatment objectives defined by the Hamilton Harbour Remedial Action Plan, the Ministry of Environment, Conservation and Parks and the Federal Environmental Protection Act. Here is a link to a summary of the projects currently being implemented as part of this study: Woodward Wastewater Treatment Plant Upgrades Project Schedule (PDF, 802 KB)
| 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. |

Contractor: North American Construction Ltd. Construction began May 2019. The construction on the new Tertiary Treatment Facility is moving full steam ahead with focus now on concrete works. Phase 1 of the South Plant expansion is proceeding with concrete and mechanical works, and excavation and shoring of the new Chlorine Contact Tank is underway. Work within the Red Hill Creek is scheduled to be completed by end of 2020. |
| 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. |
Main Pumping Station Contract 1 Renderings: Final, Woodward Aerial 1 |
Contractor: Maple Reinders Constructors Ltd./Ball Construction Ltd. joint venture Construction began May 2017. Construction of new plant entrance complete as of October 2017, along with relocation of the City’s site offices. Concrete works for wet and dry well walls, as well as the service area are completed. The Main Pumping Station project is proceeding with exterior architectural works while inside the building, work continues on the installation of the 12 new pumps and associated infrastructure, along with other process, electrical, and building services equipment. |
| 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. |
