Gurugram, Oct. 3 -- To prevent recurrent waterlogging in sectors 21, 22, 22A, 23, and on Old Delhi Road, the Gurugram metropolitan development authority (GMDA) has decided to reconstruct the master storm water drain (Leg 1) from Old Delhi road to Rezangla Chowk along the Major Sushil Aima road, said officials on Thursday. According to GMDA officials, this is the only stretch of the entire 18-kilometres long drain which is narrow, causing backflow of storm water leading to waterlogging every year during monsoon. The authority is also planning to construct a culvert at Old Delhi road to ensure smooth movement of storm water. To be sure, Gurugram has three major storm water drains including the Leg 1, Leg 2 and Leg 3 also called the Badshahpur drain, which carry water from the city and its peripheral areas to Najafgarh drain. The Leg 1 drain starts from Nathupur, and passes through DLF phase 3, Udyog Vihar, Sector 23, Rezangla chowk, New Palam Vihar, Railway track crossing, Bajghera, and it finally reaches Najafgarh Drain. "The stretch from Old Gurgaon road to Najafgarh drain is nearly 3 kilometres in length and it is quite old. It has been decided to be upgraded and it will be reconstructed at an estimated cost of Rs.60 crore," said Vikram Singh, executive engineer, GMDA. "We plan to use pre-cast concrete blocks for re-construction as it is a less time consuming process. We will have to take the heavy traffic on the road into account," he said....
