Description In this third chapter we will study about Tanks and Ground Water. For thousands of years our ancestors have tried to use run-off rain-water by building tanks. Most important thing is that the tanks helped to prevent the run-off of rain-water and the erosion of top soils. Rainwater not only flows down the streams or rivers but also slowly goes down into the soil. This water accumulates below the ground in the gaps between rocks, pebbles, sand etc. This is called groundwater.
