Existing rooftop rainwater harvesting system is an acceptable solution for alleviating the water shortage problem in urban areas.
Roof top rainwater harvesting for existing buildings.
However practical performance need functional tool to make the real progress for the publics.
Rooftop rainwater harvesting this is the best and most effective method of harvesting rainwater for apartments as it is less expensive and if implemented efficiently helps in augmenting the groundwater level of the area.
Herein we developed a practical evaluation tool in the research.
The rooftop rainwater harvesting is a method from which rainwater is captured from the roof catchments which is then stored in reservoirs and by adopting artificial recharge techniques to meet the household needs through storage in tanks harvested rainwater can be stored in the sub surface groundwater reservoir.
