Method I: Storage
In places where it rains very frequently like Kerala and Meghalaya, rainwater can be
harvested by the storage method. In this method, we collect rain water falling on the roof
through a pipe which goes down to a storage tank. The water of the first rains are let out
as the first flush.

Method II: Recharge
In regions where we get rainfall only during a few months of the year, we collect
rainwater indirectly through the recharge method. Rainwater falling on the roof is carried
through a pipe to an underground filtering tank, from where it goes into the recharge well
and recharges the ground water. |
