Construction update: Westlake Road closure begins Tuesday, Oct. 4. Read the Traffic Advisory for more details.

Delivering clean, reliable drinking water to the community

The Rose Valley Water Treatment Plant (RVWTP) is the single largest construction project the City of West Kelowna has undertaken and construction is well underway, thanks to a federal and provincial grant of $41 million awarded under the Clean Water and Wastewater Fund. The plant is scheduled to be complete in spring 2023, prior to the summer peak demand.

The last and final phase of construction of the plant requires the installation of critical water transmission main infrastructure in the Sunnyside and West Kelowna Estates neighbourhoods.

Transmission main construction is scheduled to begin in late September 2022 and is anticipated to be complete in 2023. We thank you for your patience and understanding while we build.

  • Transmission mains construction
  • What to expect during construction
  • Detour routes - NEW! See maps and information below.
  • Active transportation upgrades

  • October 2022: Transmission main construction begins
  • Early 2023: Testing and flushing of mains begins
  • Spring 2023: Active transportation upgrades begin
  • Spring 2023: Project complete

Timelines are subject to weather, contractor timelines and other factors. Please visit this page regularly for updates.

The City of West Kelowna operates five legacy water systems that will be combined into two systems once the Rose Valley Water Treatment Plant is complete in 2023. When watermain construction is complete, these underground pipes will connect residents on the West Kelowna Estates and Sunnyside/Pritchard water systems to the new Rose Valley Water Service Area.

This summer, crews will begin installing 3.7 kilometres of underground water mains in two sections:

  • Sunnyside: On Menu Road through Ourtoland and Ogden Roads to the Ogden-Boucherie intersection.
  • West Kelowna Estates: On Westlake Road from the Starlight Crescent intersection through Parkinson Road.

To shorten the overall construction schedule, both sections of transmission mains will be installed at the same time.

When construction is complete and the plant is operational, water will flow from the treated water storage reservoir, through the distribution system and the new transmission mains to individual properties. View the map to determine if you are located within the Local Area Service (LAS) that will be serviced by the RVWTP.

The new watermains will last about 80 years and contribute to a reliable and resilient water network. To minimize impacts on the community, construction is also being coordinated with active transportation upgrades on Westlake and Parkinson Roads, from West Kelowna Road to Pettman Road and with drainage improvements on Rosewood Drive.

Before upcoming construction starts in your neighbourhood, you'll receive a letter outlining the project schedule, construction impacts and other details. During installation of the transmission mains, you can expect:

  • crews will mobilize the site
  • traffic pattern changes and periodic road closures
  • crews will dig a trench to install the new pipe
  • construction activity and equipment on the road
  • parking restrictions to allow for digging and movement of supplies and equipment
  • temporary water shutdowns as water main construction nears completion
  • restoration and finishing work

If you are travelling through the work area, please plan ahead, reduce your speed, expect delays and allow for extra time.

Together with the contractor, we will work with the public to minimize inconvenience of construction and listen to concerns and interests to ensure they are considered as construction progresses.

Detour routes will be in place during construction to help keep our community moving.

West Kelowna Estates Transmission Mains construction starts Tuesday, Oct. 4.

On Tuesday, Oct. 4, Westlake Road from Starlight Crescent to Horizon Drive will be closed to vehicle traffic 24 hours a day, including weekends until Nov. 30, subject to weather conditions, contractor schedule changes and other factors. A full road closure is required to allow crews to work as quickly as possible and ensure safety of the public.

Detour routes will be in effect through Starlight Crescent and Horizon Drive in two phases:

Westlake Road Closure Phase 1: Oct. 4 for approximately six weeks

Local residents and visitors to the Peak Point neighbourhood will use Westlake Road from Horizon Drive during the first phase of construction.

Westlake Road Closure Phase 2: To begin after Phase 1

Local residents and visitors to the Peak Point neighbourhood will use Westlake Road from Starlight Crescent during the second phase of construction.

  • Detours will be in place for motorists, while pedestrian access will be maintained.
  • Cyclists are encouraged to follow posted detours or dismount through the construction zone.
  • Access for transit and emergency vehicles will be maintained at all times.
  • Trail users can continue to access the Rose Valley trails throughout construction.

Sunnyside Transmission Main construction anticipated to begin in mid-October

Construction to install the Sunnyside Transmission Main on Menu and Ourtoland Roads is anticipated to begin in mid-October, once the construction schedule is confirmed by the contractor. Advanced notice will be provided to residents living within the work area and the public prior to construction.

To minimize the impacts to residents, construction is also being coordinated with active transportation upgrades to improve safety for people walking, cycling and driving.

Upgrades include:

  • 1,300-metre delineated path on Westlake Road from West Kelowna Road to Pettman Road
  • 700-metre bike lane on Parkinson Road to Pettman Road
  • street lighting on Westlake Road to Horizon Drive
