Namma Metro has failed to implement rainwater harvesting (RWH) in 41 km of the Purple and Green line corridors.
A report by ActionAid Association said that the rail company is also losing a major opportunity to conserve the precious resource and prevent waterlogging.
The survey, conducted in June and July, checked 1,189 pillars of the metro corridor. “Zero number of rainwater harvesting structures found across the surveyed stretch on the Green Line and Purple Line,” said Raghavendra B Pachhapur, senior project lead at ActionAid.
