What Lohit'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 Lohit sheds about 1,99,155 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?
