Rehabilitation of Chandni Chowk Sewer in Delhi
Client : Delhi Jal Board
Location: Chandni Chowk Market
Onsite India was awarded the work of rehabilitation of the Chandni Chowk sewer line. Chandni Chowk suffered from huge water logging due to its old sewers laid during the British times and internally the 98 % silted sewer also showed infiltration problems. The entire network of 1200 meters was an egg shaped brick barrel with varying sizes from downstream to the upstream. This project was a part of Delhi Government’s flagship program of redevelopment of Chandni Chowk. The project was completed successfully and on time despite the lockdown due to the covid situation
