Jacobs has been contracted by the City of Hamilton, Ontario, Canada, to provide engineering services for the Woodward Avenue Wastewater Treatment Plant Phase 2 Expansion. This project aims to upgrade and expand the city’s largest wastewater treatment plant to accommodate projected population growth and improve water quality in the region.
With an estimated capital cost of approximately $310 million (CAD $420 million), the Phase 2 Expansion represents one of Hamilton’s largest wastewater infrastructure projects. It is a crucial component of the city’s Clean Harbour Program, which aims to enhance environmental health in Hamilton Harbour, located at the western tip of Lake Ontario and designated as a “Great Lakes Area of Concern.” The Woodward Avenue plant, the largest single source of water flowing into Hamilton Harbour, will undergo treatment upgrades to improve the bay’s water quality. Jacobs previously provided design services for Phase 1 of the upgrade project, which was completed last year.
“Jacobs has supported the City of Hamilton for more than a decade with upgrades to its largest wastewater treatment plant, and we look forward to continuing that relationship with this second phase expansion,” said Jacobs Senior Vice President Chrissy Thom. “Building on our existing knowledge of the plant, we’re developing an innovative technical design that makes the Woodward Avenue plant more resilient and meets the city’s goals to remediate Hamilton Harbour, supporting community and environmental benefits while unlocking further economic growth.”
Jacobs will undertake preliminary and final design for the Woodward Avenue Phase 2 Expansion. This includes the addition of a new secondary treatment plant, expansion of tertiary treatment facilities, upgrades to solids management, and a major renovation of the existing North Secondary Treatment Plant. The project will increase the average rated capacity of the facility from 409 to 500 million liters per day (ML/d) and peak capacity from 614 to 1,000 ML/d to better handle wet weather flows during rain events. The city’s goal is to complete the project before the end of 2032 to meet projected population growth.
Jacobs is committed to challenging today to reinvent tomorrow by solving the world’s most critical problems, supporting thriving cities, resilient environments, mission-critical outcomes, operational advancement, scientific discovery, and cutting-edge manufacturing. With approximately $16 billion in annual revenue and a talent force of more than 60,000, Jacobs provides a full spectrum of professional services, including consulting, technical, scientific, and project delivery for both government and private sectors.
