MC sends proposal of Rs 103 cr for repair of main sewer line to govt
Illegal sewerage connections by hotels, banquet halls and shops and the flow of untreated effluents discharged by dyeing units is causing damage to the 7.5-km-long main sewerage line from Babail Naka to the sewage treatment plant (STP) in Sewah village, which caters to the load of sewerage flow of 16 wards of the city.
The sewerage line has caved in eight times within the last one and a half years near a hotel on the Sector 25 bypass road and in the Industrial Sector 29 part-2. Recently, a manhole of the sewerage line was also found broken, which is 100m ahead of the point, where it caved in October.
Meanwhile, the MC has prepared a proposal of Rs 103 crore for the repair of this damaged sewer line and sent it to the Urban Local Bodies (ULBs) headquarters for approval.
As per sources, the Public Health Department had begun laying the main sewerage line in 1995. The 7.5-km-long sewage line was commissioned in 2000 and is around 20-25 feet deep with a diameter between 1600-1800 mm. The sewerage lines of almost half of the town, including 17 wards here, have been attached with it.
But with time, this sewerage line weakened and caved in eight times within one and a half years. It caved in in August 2023, in October 2023, in January 2024 and in August in Sector 29 part-2. Apart from this, the sewage line caved on the Sector 25 bypass road, near Krishana Garden on November 9, near Days hotel on October 20, August 24 and 10 near Malik enclave. Apart from this, the manholes were broken due to the movement of heavy vehicles on the road.
Officials of the MC said the main reason behind the damage of this sewage line was that firstly the line had completed its lifespan and had the flow of untreated effluents which had high levels of chemicals discharged from the dyeing units through sewerage lines illegally.
Apart from it, several hotels, banquet halls and shop owners have joined connections in the main sewage line without permission or information, said a senior official in the MC.
Their plumbers kept the connections loose due to which the soil got eroded and the line caved in, he added.
Rajesh Kaushik, XEN, MC, said a detailed project worth Rs 103 crore had been prepared for the overall repair of this 30-year-old sewerage line.
The old age sewerage line would be rehabilitated with the latest technology, machine wound spiral lining (MWSL), under which this line would be repaired by doing coating inside the sewage pipes and after repair, its life would be increased to around 50 more years, XEN Kaushik maintained.
