MCG begins drain mapping in Gurugram after August waterlogging

After 75 mm of rain on August 24 left school buses and vans stranded for more than four to five hours near Subash Chowk and Sheetla Mata Mandir, MCG has started mapping the city’s drains and catchments.

The exercise covers Subash Chowk, internal sectors and licensed colonies, and will use a simulation model to track how rainwater moves through the drainage network. MCG commissioner Pradeep Dahiya said the model would help identify where repairs or capacity upgrades are needed.

The corporation is also examining ecological recharge measures rather than underground storage tanks. IIT Gandhinagar has identified 273 possible rainwater-harvesting sites, while MCG is considering injection wells capable of taking in 48 to 80 litres a second. Stormwater lines are planned for narrow lanes without dedicated drains and for low-lying areas with inadequate drainage.

The work follows waterlogging on Gurugram market roads during the monsoon. MCG has not set a completion date for the mapping or simulation exercise.
