An Innovation in UV Disinfection. WSP provided design, construction oversight and commissioning of the Duteau Creek Water Treatment Plant for the Regional District North Okanagan. WSP’s team leveraged their experience and water treatment expertise to implement a design that placed operability and reliability at the forefront and ensures the continued protection of public health. Without a filtration process, the Duteau Creek Water Treatment Plant did not qualify for conventional treatment credits and was non-compliant with the provincial health guidelines for surface water treatment. WSP’s water treatment team provided an economically sustainable solution to meet the health guidelines with a unique application of UV disinfection. Through technical and project delivery excellence, WSP met the Owner’s challenge for a $7 million solution to their $30 million problem - getting the 179 MLD (2,070 L/S) UV Disinfection Facility out to market on-time and on-budget. A $7 Million Solution to a $30 Million Problem The view of UV reactor trains from inside the UV disinfection facility.

In the summer, the lake is a beautiful bright turquoise, green colour that sparkles so beautifully you’re reminded of crystals.” To make the most of that natural wonder, RDNO is developing a paddling trail on the water, which will have buoys with wayfinding signs to show which direction to go and highlight some local opportunities while you’re out. The paddle corridor is expected to run parallel to the Okanagan Rail Trail and be intended for kayaks, paddleboards, rowboats, and canoes. Kalamalka Lake is already popular for water skiing and boating, and there have some challenges with the interface, so the water trail will set up a designated paddling area with the hopes of reducing conflicts between motorized and non- motorized vessels. With this in mind, the goal is to create a layer of safety and recreational joy for everyone. The project is in its infancy, and the RDNO is looking forward to having more details soon.
