Our canal system which is life line for our agriculture, spoiled sizable area of fertile land by seepage. The seepage can be prevented if bottom of canal is lined by cement concrete bricks and side walls by thick HD plastic sheets. Some times machines are operated in the canal to de-silt it. The cement concrete tiles will with stand the pressure of the machines and at the same time a small amount of water will percolate down to recharge ground water. This will save 60% water and stop land degradation. The spoiled land will be reclaimed in time.
