Inspite of the above observation, lining can significantly reduce conveyance losses. Lined channels have a smaller surface area for a given discharge than unlinedchannels. Typically a lined channel will have 40% of the unlined surface area for a given discharge. Therefore even at the same loss rate per unit area there will be a saving in water. When estimating the reduction in losses from a lining programme, this should be based on the combination of a reduced cross-section and a reduced seepage rate per unit area.
