The Amdavad Municipal Corporation (AMC) plans to spend around ₹3,200 crore to rehabilitate 69 ageing drainage and storm-water trunk lines, with 42 lines already completed.
The network spans 196.23 km, with several pipelines now 25 to 50 years old. Instead of replacing the lines entirely, the civic body is using modern rehabilitation technologies to restore their efficiency and extend their service life.
42 Lines Rehabilitated So Far
According to the AMC drainage department, rehabilitation work has been completed on 42 of the 69 identified lines, covering 85,896 metres or about 85.89 km.
Around ₹950 crore has been spent so far. The work is aimed at addressing the declining capacity of old trunk lines, particularly in parts of the city where increasing population and development have placed additional pressure on existing drainage infrastructure.
Laying new pipelines in older and densely populated areas would require extensive road excavation and cause major disruption. The AMC has therefore opted to rehabilitate existing pipelines from within using modern techniques.
Work Underway on 11 Lines
Rehabilitation work on another 11 lines is currently in progress at an estimated cost of around ₹440 crore.
The projects cover approximately 34,907 metres, or 34.90 km, of drainage and storm-water pipelines across different parts of Ahmedabad.
The ongoing work includes lines in the Asarva ward and stretches between Maganpura Circle and Ramji Mandir, Bhaktinagar New Vidyavihar Society and Joggers Park-Radhaswami Road, Andhjan Mandal Crossroads and Helmet Crossroads, and AEC Bridge and Pallav Crossroads.
Other sections under rehabilitation include routes from Sainik Petrol Pump to Shivranjani Crossroads and Andhjan Mandal Crossroads, Makarba Torrent Power Substation to Sadbhavana Circle and Amber Tower, and Nirant Crossroads to the Express Highway Junction.
East and South Ahmedabad Also Covered
Several major drainage stretches in the eastern and southern parts of the city are also being rehabilitated.
These include the Danilimda Crossroads-Chandola Lake stretch, Khokhra Crossroads-Hatkeshwar Circle, Rajeshwari Colony-Govindwadi-Isanpur Bridge, Apparel Park Metro Station-Lokman Kumbhar ni Chali and Silver Flats, and Bhaipura Ward Office Junction-Dhiraj Housing-Model Road.
Rehabilitation is also underway on sewer trunk lines from Nikol Crossroads via Palm Hotel to Odhav and from Tapasvi Icon to Hatkeshwar Circle.
North-West Zone Has Largest Share
The North-West Zone accounts for the largest number of identified pipeline sections, with 26 lines slated for rehabilitation.
Projects include drainage lines from Ratna Park to Karmacharinagar Division-2, Karmachari School to Karmacharinagar C-Type and Chanakyapuri Bridge to Kargil Crossroads.
The Sola Bridge-Bhuyangdev Crossroads-AEC Crossroads stretch is also being taken up. The pipeline between Pallav Crossroads and Chanakyapuri Bridge is being rehabilitated using the GRP method.
₹1,800 Crore Plan for 16 More Major Lines
The AMC has prepared plans to rehabilitate 16 additional major pipelines in the next phase.
The proposed work is estimated to cost between ₹1,800 crore and ₹1,850 crore and will cover 75,432 metres, or around 75.43 km, of pipeline.
Four lines each have been selected in the North and East zones. While rehabilitation of all four selected lines in the North Zone has been completed, two of the four lines in the East Zone have been completed.
AMC Seeks Longer Life for Existing Network
The drainage department said many of Ahmedabad's major trunk lines were laid decades ago and are now under greater load than they were originally designed to handle.
Rehabilitating the lines from inside allows the civic body to strengthen the existing network without undertaking extensive excavation and laying completely new pipelines.
The AMC expects the approach to improve drainage performance and extend the operational life of the ageing network, while reducing the risk of drainage overflows, waterlogging and sinkholes linked to pipeline failures.
