NEW DELHI: The New Delhi Municipal Council has decided to go in for the next phase of upgrading its sewerage lines. The plan involves installation of new sewer lines and rehabilitation of old lines through de-silting and augmentation of their existing carrying capacity.

According to the NDMC authorities, out of the proposal to lay additional lines measuring 51 km, the civic body has already laid 31 km in the earlier phases and is now gearing up to undertake the remaining works in the VVIP zone and the diplomatic area on a priority basis.

The works to be included in the current phase include augmentation of sewerage from Motilal Nehru Marg opposite Air Headquarters to Mansingh Road, from Chandra Gupta Marg to Akbar Bhavan in Chanakyapuri, and from Kamal Ataturk Marg to Prithviraj Road. In addition, the civic body will also be augmenting sewerage in Golf Links Area up to Lodhi Road and in Aliganj and Jor Bagh.

Apart from laying new sewer lines, the civic body plans to rehabilitate sewer lines on Teen Murti Marg, Akbar Road, Tughlak Road, Tees January Marg and Prithviraj Marg, from Tyagaraj Marg to Dupleix Road, Subrahmania Bharti Marg, Motilal Nehru Marg and Q point. Rehabilitation of sewer relief line from Q point to Zakir Husain Marg and from Bhai Veer Singh Marg to Parliament Street is also under consideration.

These schemes are scheduled to be completed in the next five years with an estimated budget of Rs.150 crore. The civic body is also hoping to access funds for these projects under the Union Government’s Jawaharlal Nehru National Urban Renewal Mission.

According to the NDMC, the overall sewerage network of the civic body is about 350 km in length and handles a sewerage discharge flow of 104 million gallons per day at 80 per cent of water supplied.

Said an NDMC official: “The main problem with our sewer lines is that they were laid in the 1930s and have not been upgraded since. In addition, increasing population pressure has also added to the discharge being carried by these lines and this now requires us to increase the carrying capacity of these old lines by increasing their diameter. Since we cannot re-lay these old lines, we plan to de-silt and rehabilitate them and add new lines to our existing sewerage network.”

To facilitate completion of this ambitious project, in addition to the traditional open cut-and-cover method, the NDMC will be using advanced micro-tunnelling and trench-less technology along with a unique cured-in-place-pipe technology which enables restoration work without disturbing the existing position and alignment of the sewer line.

Another NDMC official said:“These latest technologies will enable both augmentation of new lines and rehabilitation of old ones without digging and causing minimum inconvenience to the road users.”

Apart from implementing new schemes, the NDMC also plans to complete its backlog of prior schemes which are currently in an advanced stage.

These include de-silting and rehabilitation of part of trunk sewer of Khushak Nullah near Brigadier Hoshiar Singh Road and a trunk sewer line from Q point opposite Taj Hotel to Dyal Singh College and laying of a sewer line along Kamal Ataturk Marg, Aurangzeb Road, South End Road up to Subrahmania Bharti Marg and branches thereof.
