Ahmedabad: Overflowing of sewerage lines to be a thing of the past soon

Overflowing of sewerage lines will soon be a thing of past. The civic body has come up with two projects worth Rs 245 crore that will enhance the sewerage capacity in the city, said top officials. Work on Rs 120 crore line for sewerage water in the western part of the city has already begun, while planning is going on for a similar line in the eastern part of the city. Officials claimed that for the first time in the city trunk-lines will be laid using the micro-tunneling technique.

"Unlike conventional technique where the entire stretch of road is dug up to lay the sewerage line, large pits will be dug for the laying and removal of the shafts. This will ensure that there's no hindrance to vehicular movement while the work in being carried out underground. This technique is used in the creation of lines for Metro train network. We are using it for laying sewerage lines," said Vijay Nehra, commissioner of Ahmedabad Municipal Corporation (AMC) while interacting with the media persons on Friday. This will put an end to overflowing of sewerage lines in the city, he claimed.

The trunk-line in the western part of the city will cover the area from Vadaj Circle to Mahalaxmi Char Rasta — a stretch of about 6.5 km. "Sewerage water from existing lines will be diverted into this line and transported to the Sewage Treatment Plant (STP) and Vasna for treatment. It will have the capacity to transport 55 crore litres of sewerage per day," explained N K Modi, city engineer.

Work has begun in Vadaj area and it will take about two years for completion of the trunk-line. The machines for the work are expected to arrive in about a fortnight. The lines will be of different diameters of 1400 mm, 1600 mm, 1800 mm and 2200 mm against 450 mm lines under the existing network.

A similar line will also come up for transport of sewage water in the eastern part of the city with an estimated investment of Rs 125 crore. Tenders were floated, and the process of finalisation in underway.
