What Gomati's rain is worth to a building
Every millimetre of rain on a square metre of roof is a litre of water. A 100 m² roof in Gomati sheds about 2,19,810 litres in an average year, most of it in four monsoon months. Sent into a recharge pit, it refills the ground instead of flooding the street.
Your building: how much can you recharge?
1 mm of rain on 1 m² is 1 litre. The surface factor allows for water lost to splash, evaporation and first-flush.
