We are the first Company in India to have carried out Cured-in-place-pipe (CIPP) Lining of such large sewer lines under most difficult and arduous working conditions and have successfully completed the project. Even though installation process is highly challenging because of the infrastructure involved, we decided that this would be the best suited for Indian conditions, primarily on account of the total absence of joints and the possibility of stringent quality control and production and installation phases resulting in flawless and joint less sewers

This specific job involved a 3.4 km long, badly damaged sewer of 1.6 meter diameter, at a depth of around 30 feet below the surface in unstable strata with a ground-water head of almost 25 feet. The sewer crossed thickly populated and constructed areas as well as arterial roads such as the Ring road in Delhi. The sewers were 80 to 100% full of silt, and that there was a very severe water infiltration problem. The unstable soil conditions coupled with the displaced joints, sinking manholes and sewer settlements compounded the rehabilitation challenges. The critical sewer situation was because of the non-functioning and deficient levels of the sewerage infrastructure. We located and exported the necessary technology for Sewer Rehabilitation to India that would provide Rehabilitation and trouble free service and ensure a trouble free performance for the sewers for decades.

Where there were no or very little out flow (2MGD) now the out flow has been achieved to 9 to 12 MGD.

 

DJB had 5 trolleys (pumps) in different part of the sewer line to help the line to flow. All 5 Trolleys are now removed, giving the public their freedom and cleaner environmental.

     

 

We pride ourselves for taking all necessary safety precautions towards ensuring a safe and hassle free working condition.

We have a deep commitment to making all necessary efforts towards improving the condition and asset-performance scenario, specially of the underground Utility assets in India which are often neglected, or out of reach due to construction of new habitations, but are critically important to the quality of life of the citizens. We are confident that our commitment to this purpose shall bear fruit in the near and long term scenarios along with the change-initiatives towards efficient performance and international class services.
