Patna: Residents can expect relief from waterlogging problems in low-lying areas of Patna and nearby areas like Danapur, Khagaul and Phulwarisharifwhile the state government has approved the ambitious stormwater drainage project, which will be executed by the Bihar Urban Infrastructure Development Corporation Limited (BUIDCO) at an estimated cost of Rs 957 crore.
According to the detailed project report prepared by the Hyderabad-based private agency, the 185 km long drainage network has been divided into nine lots (catchment areas) and will reduce the waterlogging problems of Patna municipal area and neighboring areas for the next 30 years. years. BUIDCO will launch the bidding process to start the construction of the stormwater drainage network, which is expected to start in September-October after the monsoon.
According to the Managing Director of BUIDCO, Dharmendra Singh, the city experienced waterlogging and flooding issues in 2019, following which the Department of Urban Development and Housing decided to prepare the drainage master plan. “After the rainy season, work will start simultaneously in all the watersheds. Efforts will be made to complete this plan within the next 18 months and it should be operational before 2024. The problem of waterlogging will be solved once the drainage is done,” he told this newspaper on Saturday.
“The master plan was only prepared after conducting a thorough survey and scientific study of watersheds, low-lying areas, geographic information system mapping, contour mapping, outlet of drainage water, groundwater and sumps, among other parameters. Apart from the construction of storm water drainage networks, new sumps will also be constructed in different areas,” Singh said.
In this project, 103 drainage pipes will be constructed and they will be divided into different lots. Catchment I will be 37.04 km long and cover Danapur and Khagaul areas, Catchment II will cover Phulwarisharif and will be 10.74 km long. In Catchment III, the major areas are Ashiana Nagar, Jagdeopath, Raja Bazaar, Yadav ColonyNirala Nagar, Digha, Rajiv Nagar and Rupaspur, covering a network of 20.35 km in length.

Once the stormwater management project is completed, there will be no flooding or waterlogging in Patna for the next 30 years,” Gautam said.
