A GMDA spokesperson said that authority CEO PC Meena had conducted a field visit of the Leg 4 drain, and other storm water drainage works on Sunday to ensure that the work is completed before monsoon.The visit by GMDA CEO comes a day before Haryana chief minister Nayab Singh Saini is set to arrive in the city. Also, union minister for housing and urban affairs Manohar Lal Khattar has asked the GMDA to plan and construct a drain which can take storm water from the city to Yamuna via Sohna, Nuh and Palwal.The Leg 4 drain is being constructed parallel to National Highway-48, extending from Vatika Chowk to NH 48. This drain is approximately 9 metres wide, 3 metres deep, and has a carrying capacity of 1,400 cusecs. During the inspection, officials explained that once Leg 4 becomes operational, the pressure on Leg 3 (Badshahpur Drain) will be alleviated, and excess rainwater can be diverted towards Leg 4 via a gate system when required.Subsequently, CEO Meena inspected the drain currently under construction near the Tau Devi Lal Stadium. Officials informed him that this project is expected to be completed by June 15, and it will minimise waterlogging near Medanta underpass and the Medanta road.The officials also said that a new drain will be used to channelise rainwater accumulating near the National Highway directly to Leg 3 from the outskirts of Khandsa village. The drainage system is set to become more effective through the use of barrels being constructed using trenchless technology near the Sunbeam Factory at Narsinghpur, they added. The GMDA CEO also reviewed the progress of the three barrels being constructed beneath NH-48 using trenchless technology.In Sector 37D, the CEO directed officials to expedite the work of constructing a junction of drains to ensure its completion before the onset of the monsoon season. “GMDA is prioritising the completion of all critical drainage projects before the onset of the monsoon season to ensure that citizens do not face any inconvenience during the monsoon,” Meena said in a statement on Sunday.
