For this open farm irrigation channel a simple and traditional method of waterproofing was used. The open channel suffered significant water loss through evaporation, however the most damaging loss was through below ground seepage due to porous soil conditions.
The water flow was simply restricted whilst Mr Waterproofing laid and installed the PVC liner for sectional lengths of the channel. Water flow was then restored and the channel was instantly operational.
This simple method of preventing water loss increases effective irrigation at minimal costs. The water savings have equated to millions of litres.
