A secure and reliable potable water supply for the communities of Wandering River and Grassland
The Wandering River regional waterline is a 150-milimetre, 88-kilometre system that extends from Boyle to Wandering River via Grassland in Athabasca County.
Wandering River’s existing water treatment plant was scheduled for demolition by the end of 2012, necessitating a new potable water supply source. The solution? A regional water system extension would enable a connection to the community of Grassland 55 kilometres to the south as well as the farming and acreage owners along the proposed system.
The system consists primarily of fusible polyvinyl chloride (FPVC) pipe. This represents the largest project by length of FPVC pipe directionally drilled and installed to date in North America. This was also the first regional waterline project in Alberta completed using a design-build delivery.
Directional drilling was used for the entire length as it presented several advantages including winter construction, reduced cleanup, and minimized disturbances to landowners. In fact, as the project was nearing completion, the owner shared with the design-build team the story of a local resident who was curious as to when construction was scheduled to commence!
With this project, Alberta embarked on a significant new chapter in the construction of potable water systems. Our team and the design-build team undertook this project with the understanding that success or failure here would directly impact future opportunities to carry forward the design-build methodology for municipal water systems. Through a committed team effort from the owners, operators, designers, contractors, sub-contractors, and others, this project was a huge success.
