East Victoria Water Channel Lining
Geofabrics provides clients with effective options for wastewater capture, storage, distribution and treatment through an innovative range. One of the local water authorities had an issue with an existing water channel. About eight kilometres of the 42 km channel was leaking due to a lack of maintenance over the last ten years. This led the EPA getting involved and working with the water authority to find a potential solution. One of the options was an underground pipeline, but it was ruled out due to cost. They decided to try several solutions which included HDPE, GCL and Concrete Canvas in different sections to determine the best solution.
The channel is a critical asset and can only be turned off for four to five days as there is not enough storage in the system. Diverting the channel was an option but too costly for the initial trial.
"Concrete Canvas was a preferred solution during the trial as it was quick to install and could be done using their internal staff. It also offers a 50-year life which was necessary as the client is looking for a permanent solution."
The initial feedback is positive towards Concrete Canvas, and this could initially cover up to eight kilometres of the channel that has been recognised as needing remediation in roughly one-kilometre stages. Geofabrics worked with the client so the overall solution in terms of speed of installation and longevity would benefit the client in the long term and save costs.
