Deep Tubewell/ Deep-set Pump
Deep Tubewells & Deep-set Pumps have become very popular to the people of those areas where due to arsenic contamination and declination of groundwater table, shallow Tubewells have become inoperable. The water from this technology is free from any kind of pollution. Deep Tubewell generally installed in deep aquifer passing over two impervious layers. This tubewell operates same principle of no. 6 well as shallow tubewell when the static water table is within the suction limit. On the other hand, when the static water table goes beyond the suction limit the pumping mechanism switched to force mode in stead of suction mode in the case of Deep Set Pump.
