The Town of Renfrew’s WTP was originally established in the early 1950s, and expanded and upgraded in the early 1970s, the engineering for which was provided by JLR. Following the Walkerton tragedy, JLR was retained by the Town of Renfrew to undertake various detailed evaluations of the plant facilities in consideration of new regulations and various operational constraints, and to prepare water system’s first Engineers Report. Many of the issues identified were associated with the raw water source, which is particularly challenging to treat. Short and long-term action plans were developed, along with capital cost planning, financing strategies, and conceptual level design.
Subsequent to completing all preliminary studies, JLR prepared detailed design drawings and tender documentation for a major construction contract to upgrade the WTP. The scope of tour work included preliminary and detailed design services, contract administration, and site inspection services. A Class EA was also undertaken, including pilot testing and treatability work.
This intricate construction project saw upgrades literally implemented over top of existing plant equipment and facilities while the existing systems continued to provide drinking water to the town’s residents. New systems were tested and brought on line as they were completed, and old systems were taken off line and decommissioned.
Improvements included new low and high lift pumping systems, a new two-train clarification system (Acitflo) with provisions for a third train in the future, a new residuals treatment system, a second clear well, new standby power, all-new chemical storage/feed systems, and many building system improvements. This project provided a complete renewal of the existing plant and will allow the Town of Renfrew to service the community for many years to come.
