Canal liners can be used in both irrigation and drainage canals as they serve to control water flow and prevent seepage in either application. Drainage canals and irrigation canals will have some differing focuses however when it comes to considering specific needs.
When lining a drainage canal, it's important to consider managing water with high sediment or pollutant content and ensuring the liner can withstand corrosive or chemically reactive conditions. The liner must also handle fluctuating water levels and potential debris that can cause wear. For irrigation canals, the priority is preventing water seepage to maintain consistent flow and reduce water loss, particularly in areas with porous soils. The material used must be durable and compatible with the surrounding environment to ensure efficient water delivery to agricultural fields.
