Construction of Powell River's new Consolidated Wastewater Treatment Plant (CWWTP) was substantially completed in June 2023, and was formally handed over to the City's Infrastructure and Operations Department shortly thereafter. Engineering and Operations staff were initially integrated into the plant operations beginning in March 2023, as wastewater began to flow through the facility. By the time formal handover was reached, the City’s wastewater operations staff had received extensive training and were effectively managing all aspects of plant operations.
Environmental Impact
This leading-edge facility significantly improves how Powell River treats wastewater in order to minimize human impact on the marine environment.
City of Powell River Mayor, Ron Woznow "The new consolidated wastewater treatment plant has a life expectancy of 50 years. During this time, it will significantly improve the treatment of our wastewater and minimize our impact on the marine environment," said Powell River Mayor, Ron Woznow. "It also more than complies with existing effluent quality standards and we are confident it will allow the City to meet any new treatment standards." - Mayor Ron Woznow
The facility is currently exceeding Government of Canada Wastewater Systems Effluent Regulations (WSER) and the BC Government Municipal Wastewater Regulations (MWR) for effluent quality standards and is designed to be upgraded to meet future treatment commitments when necessary. The CWWTP is easier to operate, maintain and administer than the three antiquated facilities it replaced.
Conveyance
Outfall in-shore end, July 2022The CWWTP treats all of Powell River's wastewater conveyed from four neighbourhoods - Wildwood, Cranberry, Townsite and Westview, and there have been discussions with Tla’amin Nation to treat their wastewater as well. For now, the City's sewage and wastewater is collected from existing systems through four new pumping stations and approximately eight kilometres of new pipe to the CWWTP for treatment, and the effluent is then discharged through a new state-of-the-art outfall, designed and engineered with enhancement of the receiving environment habitat in mind.
Funding
The City thanks the Government of Canada and the BC Government for their investment of $30,400,000 and $25,330,800, respectively, totaling $55,730,800 in joint funding. The City is grateful for the support from both senior governments.
The CWWTP is the largest public infrastructure in the City's history and is partially funded by the Investing in Canada Infrastructure Program (ICIP). Through ICIP, British Columbia communities cost-share infrastructure investments between the Federal, Provincial and Local governments, as well as other partners.
Thanks to the Team
City of Powell River Engineering Services [from left] Manager of Engineering Services, Nagi Rizk, Tully Kurtz, Brett Osualdini, Janice McLean, Director of Operations and Infrastructure, Tor Birtig, Kyle Bombardir, and Mik Drosdovech "I have had a long career and worked in many cities with many people, and hands down this engineering team is the best.
With all the challenges we faced on this project, including the COVID-19 crisis and supply chain challenges, this team was relentless, dedicated and unwavering to bring this project to completion.
I can’t be more proud of each of them and their support for each other.
Their outstanding work has resulted in a project our City will be proud of for generations to come." - Nagi Rizk, Manager of Engineering Services
We wish to thank our consultants for overall project management; the general contractor, Graham Infrastructure, all of the subcontractors, local businesses and the women and men responsible for building the plant, constructing the linear works and installing the four pumping stations so quickly. The entire project was completed in just over two years, from May 2021 to June 2023, which is a very significant achievement.
Scope of Work
The work generally involved bulk earthworks, underground utilities, retaining walls, roadwork, structural concrete work in the Odour Control Unit (OCU), Process Building and Bioreactor Complex and a timber-framed Administration Building. Internal building components consist of process pumps, blowers, motors, valves and a significant amount of mechanical piping, electrical equipment, HVAC and SCADA control systems. Specialized process treatment systems include two high-capacity Hydro-Dyne center-flow screens, two Hydro-Dyne washing-compactors, a Veolia vortex grit-removal system, four Ovivo aerobic bioreactor aerations systems with Aerzen hybrid blowers, four Ovivo secondary clarifiers contained within Dennerik stainless-steel tanks, three Wedeco ultraviolet disinfection reactors, a Sulzer dissolved aeration flotation (DAF) system, two Ovivo digesters (with Aerzen turbo blowers), two Haus dewatering centrifuges, an Aquafy chemical dosing system, the Biorem OCU and a Claro Septage Receiving System (SRS).
This engagement is provided in accordance with City Council’s Strategic Priorities and is in keeping with the City’s commitment to the principles of openness, transparency and accountability.
