Around 70% water is lost between the storage and usage points. The lining of canals, ponds & reservoirs helps in reduction of seepage losses. Polyethylene film lining alone or in combination with conventional lining materials has proved to be an effective seepage proof method in canals, ponds and reservoirs. Such ponds can be used for irrigation, fisheries, livestock as well as domestic purposes.
ADVANTAGES OF LINING
- Prevents seepage losses.
- Provides water for critical irrigation.
- Overcome drinking water scarcity.
- Checks salinity migration.
- Non-contamination of brackish water.
