The sewerage system of Mumbai, the financial capital of India is a century old and the city experiences massive rains every year. Last year however the season’s entire rainfall was received in just 21 days, water logging in all low lying areas including N.M Joshi Marg where the Brihan Mumbai Municipal Corporation has been promising relief to residents, users and commuters for long but to no effect. N. M Joshi Marg was under 8 to 10 inches of flood water and life almost comes to a standstill every year. Onsite India was awarded the work of rehabilitation of this sewer. Our team reached the site for a CCTV survey and the images from the survey have been furnished below. The line had multiple problems like ground water infiltration, deformity, intruding roots to mention some. A 50 meters stretch in this line was totally cracked and could have collapsed any moment. Our team took immense care to survey down this area but finally we were successful in producing the entire footage to the BMC who decided to rehabilitate this as soon as possible to save themselves and the civic life from immense amount of catastrophe.
