DSI is the pioneer of pipeline inspection robotics in India. DSI started the indigenous manufacturing of pipeline inspection robots in 2007 while executing the inspection works for Delhi Jal Board for the work of rehabilitation of trunk sewers in Delhi. DSI has already established itself as the key player in the sewer industry with its state-of-the-art indigenously manufactured, Beaver series Pipeline CCTV Inspection Robots, that have saved thousands of crores of rupees for the Indian government due to their effective usage in the assessment and evaluation works of sewer pipeline infrastructure projects. The Beaver series has now replaced all its foreign competitors across India and has become the unanimous choice of all contractors for sewer pipeline inspection works. The controlling software and panel is at par or superior in performance and features to most systems across the world.
