Conventional lining method like brick and tile lining are either too expensive or not sufficiently effective.

Polyethylene film lining alone or in combination with conventional lining has proved to be a seepage proof barrier between the soil and the water.

• Lining of ponds and reservoirs improves water availability over a longer period of time.
• It is highly useful in porous soils where water retention in ponds and water harvesting tanks is minimal.
• This technique can also be used in the lining of salt pans for improving productivity as well as quality of salt.
• Technique is suitable for effluent ponds and channels to reduce soil and ground water contamination.
• Economical and effective method of storing water.
• Prevents loss of water through seepage
• Eliminates water logging and prevents upward intrusion of salts into stored water.
• Useful for the purpose of storage of drinking water, for pisciculture and for providing supplementary irrigation. A large number of ponds have been lined with plastics for providing drinking water in the coastal and hilly areas of Gujarat, West Bengal, Karnataka and Himachal Pradesh.
• Lining of effluent ponds for pollution control.
• Shortens gestation period of crop growth.
• Prevents soil erosion.
  

• Increase in the hydraulic efficiency of the canal system
• Prevent seepage losses
• Prevent breaches in the embankment
• Eliminate water logging and soil salinity of cultivable land through which canal/distributory passes.
• Reduction of weed growth in the canals.
