Appreciation of Rainwater harvesting potentiality for sustainability in reduction of water stress-A case study of Guntur, Andhra Pradesh, India.

Rainwater harvesting is the method of collection, store and use of rainwater where ever it falls. Tropical climatic conditions will receive extreme precipitation, i.e. in form of rain. Water stress and scarcity is happening around the world especially in urban areas as the demand is more because of density of population. As the infrastructure of basic needs at urban areas are almost up to the level, the paved areas will be present in most of the areas. The gap between supply and demand is varying much essentially in urban areas. Thus, the rainwater harvesting at plot level as well as at community level is becoming very much essential so as to minimize the gap between demand and supply. The harvested water lead to supplement the main supply of water and lessens the pressure on main source of water for the existing urban settlement. The present paper deals with the frame work for sustainable rainwater harvesting at a town level. The paper deals with correlating the selected eight study pockets in Guntur town, Andhra Pradesh, India by making the grouping of plots based on the area of the plots with regard to dwelling units related to occupants. The correlation analysis directed to establish strong relation between different study pockets with respect to LPCDs to workout settlement level Sustainable harvestable rainwater frame work with due consideration to density of population, slope, topography and meteorological parameters etc. [ABSTRACT FROM AUTHOR]
