Canal liners are important in order to prevent water seepage. Without a canal liner, water will seep into the ground much easier, resulting in water loss and reducing the canal's efficiency. Using an impermeable liner in a canal helps maintain consistent water levels, ensuring reliable delivery for irrigation, industrial use, or navigation.
By minimizing seepage, a liner also protects surrounding soil from waterlogging and prevents the canal from eroding, which could compromise its structural integrity. In areas with sandy or porous soil, a liner is crucial for maintaining the canal's function. Proper lining reduces maintenance costs over time by decreasing the need for repairs and improving the canal's durability and performance.
