Canals have long been known as an efficient source of water that can be used for a variety of purposes such as agriculture, irrigation, water conservation, etc. However, one of the key challenges that lie with canals is seepage loss that leads to almost 40% wastage of water. In that regard, canal liners are used that help resist the flow of water through the bed and sides of the canal. The lining can be made using various materials such cement, concrete, plastics, boulders, bricks, etc. The main objective of canal liners is to protect the water from seepage loss. Using a canal liner can reduce water loss through seepage by up to 60% to 80% as compared to an unlined canal.
Essentially, there are two types of canal linings:
- Earthen type canal liner – are of two types:
- Compacted earth lining: This canal liner is recommended to be made in canals that have earth in close vicinity. In that case, it is a cost-effective and efficient option.
- Cement earth lining: Made by mixing sandy soil, cement and water, which hardens to a concrete-like material, cement earth lining is great for erosion protection and providing strength for large channels.
- Hard surface canal liner – are of three types:
- Cement concrete lining: One of the most widely used canal liners, the cement concrete lining is tough, long-lasting, impermeable. It can be used for small or large channels.
- Brick lining: As the name suggests, brick lining is made by lining bricks and smoothening the top and sides with cement mortar.
- Plastic lining: A relatively newer type of canal liner, plastic canal liner can be made using polyvinyl chloride, high molecular high density polyethene and low density polythene. It is a promising alternative to cement/earth liner. HDPE canal liner, a variety of plastic canal liners, is a great technology as it allows for large applications that require UV and ozone resistance, chemical resistance, and high-quality installations.
