Vanarai Bandhara

Vanarai bandhara or Bunds are constructed across a stream or small river using gunny bags refilled with locally available soil or sand.These bags are sealed properly and are arranged in the form of a wallbarrier.This is a temporary structure built across water course to collect the water as well as to reduce the velocity of stream so that infiltration rate of water increases. It helps in replenishing the aquifer below the river bed resulting in increase in ground water level in the surrounding area.Normally Vanarai Bandhara is constructed at the end of monsoon period and it lasts till the onset of the next monsoon.
