Gurugram, Feb. 19 -- The Gurugram Metropolitan Development Authority (GMDA) on Wednesday said it has opened technical bids for the tender to appoint a consultant to construct a drain from Badshahpur near Vatika Chowk to Yamuna in Palwal along the Gurugram Sohna road. Officials said two consulting companies submitted their bids. A senior GMDA official said the work will be awarded soon to the eligible firm after financial bids are opened. The company will need to specify the route for the proposed stormwater drain and assess the structure's capacity. As per the GMDA, stakeholder departments project the cost at around Rs.2,500 crore. Officials said the drain will divert stormwater in Gurugram to the Yamuna. "During monsoons, around 12,000 to 15,000 cusecs of water from stormwater drains in Gurugram flows into the Najafgarh drain, which has a capacity of only 10,000 cusecs. This excess water normally spreads in agricultural fields but often flows back, causing submergence," a GMDA official said. The consultants must conduct topography studies, study alignment, and suggest options like diverting water into Aravalis and ponds. The drain will help divert about 30% of excess water toward Palwal, reducing waterlogging. Chief minister Nayab Singh Saini held a meeting on November 10 last year, directing a plan to move rainwater to Yamuna in Palwal following suggestions from union minister Rao Inderjit Singh and industry minister Rao Narbir Singh. Earlier, union minister Manohar Lal had directed for a plan to transport water to Palwal to curb waterlogging in Delhi and Gurugram....
