Total depth of borewell 180 feet, water trace found at 120 feet and water flow from 150 feet, but the drillers stopped the casing pipe at 100 feet in Vadavalli, Coimbatore.
Though the water flow is satisfactory through the 1 inch pipe, I want to know if it is okay to stop the casing pipe at 100 feet and should the length of casing be increased.
