What Raipur'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 Raipur sheds about 1,15,770 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?

Water you can put back each year2,31,540 L≈ 23 water tankers of 10,000 L

1 mm of rain on 1 m² is 1 litre. The surface factor allows for water lost to splash, evaporation and first-flush.
