J.L. Richards and Associates in partnership with XCG Consultants provide engineering design and construction management for the $88 million expansion of Cataraqui Bay Wastewater Treatment Plant in Kingston, Ontario.

The west-end plant on Front Road near Lake Ontario was constructed in 1962 and went through its last major upgrade in 2002. The new upgrade will increase the plant’s capacity from 38,800 to 55,000 cubic meters per day to meet projected population growth.

The work includes expanding the plant’s existing headworks and primary clarifiers, replacing the secondary treatment system, and improvements to the buildings and electrical and control systems.

BIOSTYR treatment processes are being incorporated into the processes. They combine the biological treatment and filtration of the wastewater into one system and remove ammonia, along with most dissolved contaminants and solids. The treatment will improve the quality of treated wastewater that is discharged to Lake Ontario.


According to Utilities Kingston the upgrades use a treatment process similar to the one at Ravensview Wastewater Treatment Facility. J.L. Richards won a Canadian Consulting Engineering Award for that project in 2010.

Construction at Cataraqui Bay is by North America Construction (1993). The work is being sequenced so there will be no disruption to sewer services and will begin with the construction of the secondary treatment system and dewatering facility, and then move on to the expansion of the primary treatment facility.

“By ensuring the reliability of wastewater services and helping to protect Lake Ontario, this project will benefit the community today and generations to come,” says Jim Keech, president and CEO of Utilities Kingston. The upgrades were identified as priority for the City of Kingston in its 2010 sewage infrastructure master plan and are the city’s largest item in its 2015-2018 capital budget.
