The Marriott Drilling Group offer a range of drilling and bespoke services to the water and geothermal industries. With operating bases throughout the United Kingdom, Central America and Africa plus a wide range of state-of-the-art drilling rigs and ancillary equipment, we are able to successfully complete a range of drilling and engineering projects ranging from small domestic wells for single properties to large multi-well municipal water supplies. In addition to highly trained and experienced onsite crews we also have a management team containing professional geologists and civil engineers who are able to offer advice on the feasibility of developing a groundwater supply at a given location and any permitting required prior to drilling or aquifer-testing. As such we are ideally suited as one-stop for clients wanting either a unlicensed domestic (less than 20,000 litres a day) or commercial sized water well. We are also able to offer a wide range of remedial services for rehabilitation of expoorly performing wells which can significantly increase the yield and quality of a groundwater source. These improvements generally consist of chemical and/or physical cleaning with the resulting improvements being quantified by our pump testing engineers and analysed by our groundwater experts. At our main central depot in Chesterfield we stock a wide range of submersible pumps, motors and ancillary controls for water supply systems from leading suppliers meaning that we can react quickly to emergency breakdowns when things go wrong.
