Brief Description

Description :

Ground water is an important source to meet the water requirements, hence reliable estimation of ground water resources is the need of the hour. Commercially available water level measuring equipment are expensive, hence RuTAG IIT Delhi took the initiative to design and develop low cost ground water level measuring device, so that the technology would be accessible rural farmers. It is an electric switch-type device, with electrodes having open ends attached to a wire, which is further connected to a battery and a beeper. When electrodes encounter conductive fluid, the circuit is completed & buzzing starts and depth is measured from the marked cable. Salient Features of the Device: Complies with ISO 15896:2011. Probe is made with Stainless steel rust resistant material. Probe is an assemblage of four parts i.e. Plumb bob, perforated tubular body, high pressure cord holding gland, and a sensor. One end of the probe is a plumb bob for vertical stability and other end for holding electric cord through a leak proof gland. Improved operational stability using plumb bob as added mass. Better quality cord for high tension load capacity. Light-weight aluminum casted cable spool with better operational life. Impact of the Technology: Used by Central Ground Water Board, Ministry of Water Resources, Govt. of India. A new company at IIT Delhi extended the product to a contactless device ( Rationing of ground-water for irrigation purposes. To sensitize the stake holder (especially farmers). Scientific ground water exploration. Monitoring of ground water levels. Success Stories: Being used by Central Ground Water Board, Ministry of water resources, Govt of India. Vendors have been identified for fabrication, manufacturing and assembly. Benefits from Industry Collaboration: Improved industry academia relations. Better market penetration. Dedicated vendors/manufacturers. Tentative Cost of Device is about Rs. 15,000.
