To meet the growing population demands rainwater harvesting is the need of the hour. The study area was a site in Kathacheruvu Village, Anantapur District. Past rainfall records were collected and annual rainfall was computed. Water levels in the open wells and bore wells near the site were measured at suitable intervals during pre and post monsoon season. A rain water harvesting structure i.e. check dam was designed and constructed. Water levels were increased by and large due to construction of check dam as visualized from the depth of water level records. It was also observed that for every 5 m rise of water level, power required is reduced to half.
