Borewell: A submersible pump suitable for

A submersible pump suitable for a 6” (inch) bore well, will have outer diameter of the main pump body (motor + pump) at about 5 and odd inches to allow necessary margin of gap for lowering and rotation of the pump. The outer diameter of a pump suitable for a 6” bore is already fixed by the pump manufacturers. Usually the diameter of the rising pipe which brings water to the surface for a 10 HP pump is to the order of 2” – 3” depending on discharge. Borewell FAQ, Part I : Covers topics from the initial planning, selection of site to final commissioning. Borewell FAQ, Part I I : Deals with maintenance of the structure and problems associated with existing borewells. Loose fitting of casing pipe. The seepage water from the top loose formation while trickling down will carry the colloidal clay particle and enter into the bore well through the gap between seating and pipe end. The trickling would be a flow if you have met with good water yielding zone in the loose ... It ensures the safety of those in the vicinity of the bore well. It prevents surface water infiltration and vertical movement of polluted or contaminated water into an aquifer and contamination of the groundwater quality regime of the area. Proper decommissioning conserves the aquifer yield and hydraulic head as well as the groundwater quality parameters. It prevents fall of animals and small kids into the bore wells. An abandoned well, not property decommissioned, poses a potential risk and ...
