Bihar’s State Urban Development and Housing Department (UDHD) are to prepare a drainage plan for the State capital to prevent the kind of waterlogging experienced in the city this year following incessant rain. The Department will hire a private agency to conduct scientific study of catchment, low-lying areas, geographic information system mapping, contour mapping, and outfall of drainage water, water table, situation of stormwater drainage and sump houses, among others.
UDHD secretary Anand Kishor said that based on the study, the department will make changes in the drainage system to discharge drainwater in the river in an organised manner. “Accordingly, the department will plan for pipelines and new sump houses where needed. The department has already floated a global tender to hire an expert consultant agency,” he said.
Six agencies participated in a pre-bid meeting held on November 7. According to UDHD officials, the poor condition of drainage network and inadequate pumps at sump houses and shortage of pumping stations resulted in unprecedented waterlogging in several areas of the city this year. “Our aim is to prepare a drainage plan for the next 50 years,” Kishor said.
Presently, there are nine big, 14 medium and 172 small drains in Patna. Total 38 sump houses are functional in the city while there in no pumping stations in areas like Kankarbagh, Khagaul, Danapur and Phulwarisharif.
The proposed drainage plan will cover 130 sq km area in and around the city, including Danapur, Gola Road, Khagaul and Phulwarisharif. The selected firm will also segregate the pipelines of sewage network and drainage.
