Rooftop rainwater harvesting is a simple but effective method to harvest rainwater. Over exploitation and limited recharge of groundwater is causing a negative draft of water below the soil surface. The water level and the quality of water is deteriorating due to less dilution. Rooftop rainwater harvesting produces an alternate method for domestic use of water. A study was conducted in a household located at Marjita village of Tirtol block in Jagatsinghpur district, Odisha, which lies between 20020’ 54’’N latitude and 86022’ 9’’ E longitude. The Geographical area of Jagatsinghpur district is 1668 Km2 and the annual average rainfall is 1436 mm. The gross groundwater draft for domestic and industrial water supply was estimated as 339.57 ha-m. The rooftop rain water harvesting was able to meet the 80 % of the total water required in that household on daily basis.
