Profile: J. P. Whitter (Waterwell Engineers) Ltd. specializes in well drilling and waterwell engineering. We undertake contracts and works on boreholes for many different applications including domestic, industrial, commercial, agricultural, water authority & geothermal purposes. Drilling methods used include cable tool, rotary mud/polymer, air & water flush, and reverse circulation. Cable tool drilling can achieve a verticality of better than 1 in 300, which is better than the environment agency and most water authority standards of 1 in 100, and is an invaluable method if site constraints dictate.
