Borewell casing pipes are generally used by farmers for various purposes related to irrigation and agriculture. Borewell casing pipes can be used to control the flow of water from the well. By installing casing pipes of different diameters, farmers may regulate the water flow according to their requirements. These pipes are also used to monitor the water levels in the well and control the amount of water being pumped out. This helps farmers to manage their water resources more efficiently and avoid over-pumping.
