An impermeable layer is provided at the bed and sides of canal to improve the life and discharge capacity  of canal known as canal lining. Generally seepage can result in losses of 30 – 40 % of irrigation water in canals, so this can be reduced by providing lining to the canal. 2.Importance of lining of canal  An important reason for lining a canal can be the reduction in water losses, as water losses in unlined  irrigation canals can be high.  Canal lining Minimizing water losses is very important, and especially so in schemes where irrigation water is pumped.  Reduced water losses resulting in less water to pump and thus a reduction in pumping costs. 3.Advantages of Canal Lining Ø   The seepage of water will cause very wet or waterlogged conditions, or even standing water on adjacent fields or roads.
