Rainwater harvesting systems serve as an alternative decentralized water source, in this age when groundwater supplies are depleting and municipal water infrastructures are facing high replacement costs. Decentralized water sources, like rainwater, are needed to guarantee long-term ecologically sound water supplies. The use of decentralized rainwater harvesting systems is growing nationally and internationally, especially in industrial countries like Asia, Europe, Australia, Canada, and the United States.
Implementation of rainwater harvesting is essential to fulfill the increasing water consumption by the industry, maintenance of dust due to crushing of rocks, plantations, vegetation and household users. The present work implies the hydrological analysis in association with Geographic Information System (GIS) support to obtain the water availability and its proper storage at four different locations. Various scenarios were developed, which are really useful for the Management Authorities for its proper management and utilization.
Rainwater harvesting design and installation requires a network of professionals. Component prefabrication companies, architects, engineers, craftsmen, water providers and local authority districts are involved in designing, installing and regulating rainwater harvesting systems.
