Damliners are crucial for effective water harvesting, especially in areas where water conservation is essential. Here are the key reasons why dam liners are important:
1. Prevents Seepage: Dam liners create an impermeable barrier that prevents water from seeping into the ground, ensuring that the harvested water is retained in the reservoir for longer periods.
2. Water Quality Protection: Liners help prevent contamination from soil and groundwater, maintaining cleaner water for irrigation, livestock, or domestic use.
3. Enhances Durability: By reducing erosion and structural damage to the dam walls and floor, liners extend the lifespan of the water harvesting structure.
4. Improves Efficiency: With reduced water loss through infiltration, more of the harvested water is available for use, improving overall water use efficiency.
5. Suitable for Poor Soils: In areas with sandy or porous soils where water retention is naturally poor, liners make water harvesting feasible and effective.
6. Cost-Effective: Though there is an initial investment, liners reduce the need for frequent maintenance and water replacement, saving money in the long term.
