Abstract

Rainwater harvesting is a best practice to make the water available for people during the monsoon and post monsoon season, in the areas where the precipitation is in the form of rain. In the tropical climatic conditions, the rain water availability will be abundant and in these climatic conditions, the harvesting of water will be effective. In this connection, a frame work for the sustainable rain water harvesting can produce effective results in making the water available, which includes the plot level and community level harvesting. This paper discusses the frame work for the sustainable rainwater harvesting throughAnalytical Hierarchy Processmethod(AHP)in assessing the quantity, quality and maintenance of the rainwater harvesting with respect to important components identified in Guntur town as a case study in Andhra Pradesh, India.. The sustainable rainwater harvesting has been assessed with six components such as 1. Harvestable rainwater, 2. Technical knowhow of filtration process, 3. Monitoring in dwelling Unit level, 4. Storage of rain water, 5. Institutional mechanism and 6. Urban engineering and Architectural thought through AHP. All the components were assessed with respect to the quality, quantity and management. It is found that the management of rainwater harvesting 47% as compared to quality and quantity the quality urban engineering and architectural thought indicated 47% , the maintenance and systematic monitoring of urban Local body and its institutional mechanism shown 51% , the storage capacity of the rainwater amounts to 47% and monitoring of the rainwater system to operate effectively shown 45% of weightage, with quality filtration system in the order of 44% for sustainable harvesting in neighbourhood level and at dwelling unit level.This paper identifies sustainable frame work for rainwater harvesting at dwelling unit level and community level with due consideration given to relavent weightages. Thus reducing the gap between the supply and demand
