Canal Lining | Kennewick, Washington, USA
CCX-M® used to line Highlift Canal in Kennewick
Project Overview
Kennewick Irrigation District (KID) officially established in 1917 manages more than 70 miles of open canals drawing water out of the Yakima River at Prosser Dam. In addition to the traditional challenges that an irrigation district faces such as water conservation, the district’s top priority is preventing canal breach to protect adjacent commercial and residential infrastructure.
Typically, canal breaches occur due to erosion and burrowing animal damage. In order to address both of these issues districts often employ sprayed concrete linings to canals which can be expensive and may require specialist contractors.
Solution
In November 2023, CCX® was installed by KID along a section of the Highlift Canal with an average cross section of 21ft and composed of a combination of types including sharp sand, rip-rap, clay and basalt in places. Typical flow of the canal varies during the seasons of between 1-5ft/s.
Design & Installation
- CCX-M® Bulk Rolls specified
- Channel excavated and prepared
- Transverse layup
- Perimeter edges secured in anchor trenches, material fixed to headwall
- Thermal bond and screwed overlap joints
- Hydrated using hose and water bowser
Summary
The ease of installation allowed KID to self-perform, as the material does not require specialist contractors for installation. The speed of installation was also key; allowing irrigation districts to install within tight windows between irrigation seasons and to allow the swift return of canal assets to operation to minimize water supply disruption. Two rolls of CCX® were installed in just a couple of hours and the canal was ready to be returned back into service less than 24 hours after installation.
