Project Overview

In November 2023, CCX-MAT^® GCCM (CCX-M ^®) was used to reline an irrigation canal in Dos Palos, California, USA. Henry Miller Reclamation District (HMRD) No. 2131 in Dos Palos, California, serves over 370 miles of main irrigation canals, lateral canal and surface ditches that supply water to over 47,000 acres of farmland. Mostly comprising of compacted unlined earthen canals, HMRDs priority is to mitigate seepage and conserve water.

seepage reduction when using CCX-M^®

Solution

To prevent further water seepage losses, the HMRD conducted a trial with CCX-M^®. The CCX-M^® would be used to replace a dilapidated concrete lining on a section of canal that was installed in 2004 that had cracked and was leaking. Working in partnership with Titan Environmental, Concrete Canvas USA supplied material and supervised its installation as a trial to demonstrate CCX-M^®’s efficacy as an alternative to the previously specified shotcrete and membrane solution.

Summary

The ease of installation allowed HMRD to self-perform, as the material does not require specialist contractors for installation. Using the district’s own installation crew greatly reduced installation costs, which contribute to the full 50 year design life cycle savings from the reduced maintenance of a CCX-M^® lined channel. 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.

Approximately 28,000ft² of CCX-M^® was installed in just over four days. The canal was returned back into service less than 24 hours after installation. Seepage tests were conducted on the lined canal showed a seepage reduction of 96% and CCX-M^® is being considered as an option for two significantly larger lining projects for the district in 2024.

Completed Installation

From the first time I saw the product in a water conference, I thought CCX^® could be a good lining alternative for our district. CCX^® is definitely an innovative product and one I could see irrigation districts use for multiple applications. It has some unique attributes: It is easy for our crew to install with simple tools. Cost, performance, the ability to be installed by the district’s personnel and the speed and ease of installation are important factors for every district. We were able to install CCX^® on a 1,440 feet long ditch and it looks great. The installation process was quick and easy comparing to pouring concrete, which we would have had to contract out. I expect the CCX^® to perform very well and can see multiple uses for the irrigation districts including canal lining and seepage control, vegetation control, general erosion and bank stabilization. I recommend irrigation districts check this product out.
