The City of Kingston is home to one of North America’s most environmentally progressive WWTPs, and one of the largest of its kind. The most significant municipal project in the city’s history, the $115 million Ravensview WWTP upgrade was completed approximately 10% under budget and six months ahead of schedule. The plant’s rated capacity is 95,000 cubic metres per day.
Kingston’s vision to be Canada’s most sustainable city was embraced through environmental stewardship, energy management, and sustainable design of the Ravensview WWTP. Highlights of the project include:
- LEED® Silver classification for the Administration Building.
- The connected electrical load is reduced by 0.6 megawatts during normal operation through high-efficiency turbo blowers and a 375 kW cogeneration system using biogas produced through the treatment process.
- Enhanced sludge stabilization at 55°C improves biosolids quality and maximizes the cogeneration process (Sludge stabilization mirrors the USEPA requirements for Class ‘A’ biosolids and exceeds Ontario’s current requirements).
- Indoor biosolids storage operating under negative pressure to mitigate odour impact and improve the quality of life for nearby residents.
- BIOSTYR Biological Aerated Filters for secondary treatment, one of the largest installations of its kind in North America, minimized the project’s footprint, which enabled an ecologically valuable woodlot to be preserved.
Other upgrades included:
- Modifications to the existing screening, de-gritting, and primary screening facilities.
- A new primary effluent pumping station for the secondary treatment process.
- A new sludge dewatering facility with 2 high-capacity centrifuges.
- A new, fully automated SCADA system.
As Prime Consultant, JLR provided project management, multi-discipline engineering, architectural, and planning services. Our work included the preparation of an EA, followed by on-site piloting of the preferred secondary treatment technology, detailed design, construction, and commissioning oversight. Plant operations were maintained throughout the multi-year project, and the plant’s performance to date has exceeded expectations and all regulatory requirements.
