Pond
and canal lining:
Vast amounts of water are lost through seepage, especially where the soil is gravel1y and porous.
Conventional lining method like brick and tile lining are either too expensive or not sufficiently effective.
LDPE film lining has proved to be a seepage proof barrier between the soil and the water.

These
are the advantages of LDPE film:
-
Economical and effective method of storing water.
- Prevents
loss of water through seepage.
- Prevents
breaches in the embankment.
- Eliminates
water logging and prevents upward intrusion of salts into stored
water.
- Discourages
growth of weeds in canals. Useful in effluent treatment.
- 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
