Hamilton’s municipal government has contracted consulting engineering firm Jacobs for phase two of its Woodward Avenue wastewater treatment plant (WWTP) expansion.
Jacobs is providing engineering services to upgrade and expand the WWTP, which is already Hamilton’s largest, to meet projected population growth and development objectives, to support the remediation of Hamilton Harbour on the western tip of Lake Ontario and to improve water quality in the area. The estimated capital cost of this phase is $420 million.
Under the contract, Jacobs will undertake preliminary and final design for the addition of a new secondary treatment plant, the expansion of tertiary treatment facilities, upgrades to solids management and the 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 L per day (ML/d) and peak capacity from 614 to 1,000 ML/d, to better accommodate wet weather flows during rain events. The city aims to complete the project before the end of 2032.
Jacobs previously provided design services for phase one, which was completed last year. The WWTP is the largest single source of water flowing into Hamilton Harbour, so treatment upgrades are key to improving water quality in the bay.
“Building on our existing knowledge of the Woodward Avenue plant, we’re developing an innovative technical design to make it more resilient and meets the city’s goals to remediate Hamilton Harbour, supporting community and environmental benefits while unlocking further economic growth,” says Chrissy Thom, senior vice-president (SVP) for Jacobs.
