Woodward Wastewater Treatment Plant Upgrades
Woodward Wastewater Treatment Plant Upgrades
The largest investment of the Clean Harbour program is a multi-phase plan to upgrade the Woodward Wastewater Treatment Plant. Because the plant is the largest single source of water flowing into Hamilton Harbour, the quality of that effluent has a direct and powerful impact on the harbour’s water quality and environmental health. The total budget for the upgrades is $340 million, $200 million of which comes from the provincial and federal governments through the Green Infrastructure Fund.
The planned upgrades include elevating the plant’s final treatment process from the secondary level to the tertiary (third) level. This will allow the plant to reach strict discharge limits described by the Hamilton Harbour Remedial Action Plan for phosphorus, ammonia and suspended solids.
Sub-projects at the Woodward plant include electrical system upgrades, a new chlorine tank and a new raw sewage pumping station and collection system control to support wet weather and flooding control initiatives.
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 Schedule 'C' 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.

This notice is being provided as an update on the Woodward Avenue Wastewater Treatment Plant (WWTP) Upgrade Project. This upgrade is one of the key projects under the City’s Clean Harbour Program. The Harbour is currently designated as a Federal Area of Concern (AOC) and this project will play a significant role in achieving the goal of delisting in the future. The project will involve a multi-phase plan to upgrade the treatment plant. The completion of this project will see:
- The addition of a new third level of treatment which will increase the processing of the plant’s treated wastewater. This new process will allow the plant to reach discharge targets set by the Hamilton Harbour Remedial Action Plan to reduce the impact to the Harbour.
- The total budget for this project is $340 million. $200 million of the budget comes from the provincial and federal governments through the Green Infrastructure Fund.

What is a CLC?
The WWWTP Upgrade and Expansion Project Community Liaison Committee (CLC) is a group that is comprised of 5 City of Hamilton employees, 7-10 local members of the community including residents as well as the local Ward Councillor who provides liaison to council.
The CLC is structured to provide a balance of perspectives on the Woodward Avenue Wastewater Treatment Plant Upgrade Project and was formed in partnership between the City and the local community to serve as a forum for the exchange of information between the City and representatives from the community.
The Woodward Avenue Wastewater Treatment Plant (WWWTP) Upgrade Project is a large scale project that will begin in 2017 and is scheduled for completion in 2022. During that time, construction activities will be undertaken that will impact the community. While there are significant environmental, economic, and aesthetic benefits associated with the completion of this project, the City understands the importance of maintaining ongoing communication with residents and ensuring the project and associated impacts are compatible with the community.
The CLC promotes the sharing of information, ideas and concerns regarding the project in an environment where these items can be openly shared and discussed.
CLC meetings assist in informing, engaging and hearing the community during all phases of the project. Involving community members in the project and creating an opportunity for local residents, businesses and community leaders to provide advice will help to minimize local community disruption and improve decisions and communication.
Goals and Objectives
The City of Hamilton established the CLC in 2010 to serve as one of many ways for the City and community representatives to exchange information during the planning and construction phases of the project.
Specific CLC goals include:
- To learn about operations, processes, and projects at the Woodward Avenue WWTP for the management and treatment of wastewater.
- To attend quarterly evening meetings of the CLC related to the Woodward Avenue WWTP Upgrade Project.
- To share information about quality of life, business, and other impacts occurring for City residents and businesses due to construction at the Woodward Avenue WWTP site and other similar City projects in the surrounding area.
- To identify or comment on mitigating measures to be put in place to minimize the effects of impacts.
- To identify any synergies which the Project Team can leverage that would make improvements to the community.
- To work co-operatively with other CLC members, staff, and consultants.
