Storm Water Drainage

The city has well laid out under ground storm water drainage system. The Storm Water Drainage System has been designed keeping in view the slope of the city i.e. from North West to South East. It was initially designed for a rain intensity of half inch per hour. However, because of the increased green areas/ open spaces coming under construction, the run off co-efficient has increased tremendously. This has resulted in the over loading of storm water drainage system and hence flooding of low lying pockets in the city. The Corporation had conducted a survey and identified 35 such pockets. The storm water drainage system in these pockets have been augmented by providing additional lines and road gullies. In order to meet the situation of flooding, it had been planned to augment the main trunk lines running from North to South. One trunk main running between sector 17 & 18, 21 & 22, 34 & 35, 43 & 44 and discharging in the N-Choe in sector 51 has been laid at a cost of about Rs.2 crores. To augment the drainage system additional lines have been provided in sector 7, 8, 15, 24, 28, V3 road dividing sector 34 & 44, 38, 41. Additional lines have also been provided on road leading to railway station. About 500 vertical road gullies have been provided to increase the intake of water in the storm water lines. The storm water drains have also been provided in Rehabilitation colony Maloya, Janta & Kumhar Colony sector 25.
