Onsite India was awarded the work of rehabilitation of the Chandni Chowk sewer line.

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
