bmrcl: Rainwater harvesting: BMRCL washes its hands off
Experts say the potential of rainwater harvesting to recharge the groundwater table through metro lines is enormous. According to an RWH potential estimate of BMRCL conducted by Biome Environmental Trust, a 35-km-long and 10-metre-wide viaduct of BMRCL has the potential to harvest 9,450-kilo litre of water during a 30 mm rainfall. Similarly, the RWH potential of two spans (distance between three piers of BMRCL) is 15-kilo litre during a 30 mm rainfall.
