Rainwater harvesting means catching rain where it falls and either storing it or using it to recharge groundwater. From rooftops, channel water through a first flush and filter into a storage tank for use, or into a recharge pit or well to raise the water table. In fields, slow the runoff with contour bunds, field bunding, farm ponds, percolation tanks and check dams so water soaks in instead of running off. Recharge pits and shafts near borewells and open wells directly improve their yield. Keep silt traps so structures do not clog. Even simple field bunding holds a good amount of rain in the soil for the crop. These measures suit Tamil Nadu where rooftop harvesting is widely promoted, and panchayat and watershed schemes support field structures.

I connected my house and cattle shed roofs to a recharge well. After two monsoons my open well water improved a lot. Simple and cheap with a filter drum.

Field bunding alone made a big difference. The rain now stays in the field instead of running to the road. Soil is moist longer for my crop.

Do not forget the first flush arrangement. The first rain washes dust and bird mess off the roof, and I divert that out before letting clean water into the tank. It keeps the stored water and the recharge clean.
