City of Saskatoon Water Treatment Plant Avenue H Reservoir Expansion

This project involved the construction of a new facility to house a potable water reservoir, high lift pump station, and ultraviolet (UV) disinfection facility.

The new 19 ML drinking water reservoir is adjacent and connected to the existing Avenue H drinking water reservoir and to the existing Avenue H Water Treatment Plant (WTP). The pump station includes two (2) variable speed 140 ML/d (2000 hp), one (1) constant speed 90 ML/d (1200 hp) and two (2) constant speed 45 ML/d (600 hp) pumps. The UV disinfection facility, which includes three (3) 48” UV reactors, and high lift distribution pumping station complete with associated piping, valves and instrumentation will be housed in the building to be erected on top of the new reservoir.

Work inside the existing WTP included conversion of the existing high lift pumping system to a transfer pumping system between the existing WTP and the new reservoir, including coordination of work done by others related to the transfer pumping conversion. Work also included installation of one stand-by generator in the existing welding shop building located at the WTP.

Scope of work also consisted of all related landscaping, civil, structural, architectural, mechanical, electrical, and instrumentation work.

Graham and its joint venture partner have been awarded the $273M construction contract for the Buffalo Pound Water Treatment Plant Renewal Project by the Buffalo Pound Water Treatment Corporation. This award follows the joint venture’s successful completion of Phase I early contractor involvement, which included engineering, constructability and pre-construction services for the same project.

The scope of work for the Graham joint venture includes demolition, earthworks, structural fabrication, electrical and instrumentation work, and the construction of concrete foundations and commercial buildings to deliver both new and retrofitted infrastructure. The upgrades will modernize technology and increase the capacity of the facility.

Situated near Moose Jaw, Saskatchewan, the Buffalo Pound Water Treatment Plant provides potable water to over 260,000 residents located in the cities of Regina, Moose Jaw and surrounding areas. The rejuvenated plant will be able to meet the forecasted demands of the regional requirements for potable water for decades.

This is the first Progressive Design Build water project in Canada and these upgrades should prevent any further work on the facility for at least 25 years.
