What Bijnor'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 Bijnor sheds about 99,875 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.
