Abstract


This paper attempts to investigate the implementation of rainwater harvesting (RWH) structures and its hydrologic responses (in terms of quantity and quality of water) in two hydro-geologically different localities of Chennai city in Tamil Nadu state, India. The design of RWH structures is site specific as it involves hydrometeorology, lithology and land use. Consequently, its effectiveness depends on appropriate design and implementation. Initially, a survey based on questionnaire was conducted to collect details of implemented RWH structures and analysed. Impact of RWH for possible recharge was assessed using GEC NORMS 1997 by water level fluctuation method. Water samples were analysed for different quality parameters and checked with codal requirements of IS-10500 (1991) for possible impact of RWH on groundwater quality. It is found that the recharge and quality have improved due to the implementation of RWH.
