INTRODUCTION:Jamia Millia Islamia occupies 205 acres of land at Jamia Nagar, New Delhi. It has 25% Roof top area,17 % Roads and 58 % Open Green. Rainwater Harvesting Master plan was Executed in 2003 and continuous monitoring indicates the drastic improvement in groundwater Quantity and Quality. We have Harvested 100 % Rainwater unlike Roof Top Only and there is no contamination with controlled design. We have completely avoided Water Logging, Flooding , Tube Wells failure and Salinity have been improved. We are applying this Concept to Gurgaon. Our Attempt is to develop Rainwater Harvesting Maser Plan Atlas for the entire country provided we get financial assistance from the government. Rainwater Harvesting Master Plan needs coordination among Hydrogeologist, Civil Engineers and Architecture which the rare combination available in Jamia

04/19/2304/19/23 77

The basic concept of the Rainwater Harvesting Master Plan is to capture every drop of water without contaminating groundwater otherwise only single Roof Top harvesting does solve the purpose of proper groundwater recharging.We have applied Remote Sensing, Geophysical , Hydrogeological techniques along with Structural Engineering, Geotechnical Engineering and Earthquake Engineering along with Urban Planning and Design in order to provide the safety of the foundation and buildings, Roads from Erosion due to Flooding and Water logging, improvement in the Quality and quantity of groundwater and Landscape and revitalization of water bodies. Apart from these many other ideas will be of great interest for the Architect Planner, Engineers, Social Workers and common people working in this direction. We hope that this opportunity will definitely help us to develop Rainwater Harvesting Master Plan Atlas for Bharat.

The fundamental idea of Rainwater Harvesting Master Plan was to develop the technique for capturing every drop of Rainwater because the dependability of the Jamia university is entirely on the groundwater . The situation were further deteriorating due to unplanned development in the surrounding area where the Jal board water is limited to 20 % only. Being Jamia is the only place where lot of Open Space is available the surrounding the recharging benifited a lot and Jalboard tube wells are also surviving apart from tube wells in Jamia Camus.

Comparative Study of –groundwater quantity and quality test results every pre monsoon and post monsoon in order to ascertain the overall impact of Rainwater Harvesting on groundwater quality and quantity of the campus area since the inception of its execution in 2003 till date. Apart from these the Dilution of Salinity, control on water logging and Flooding, Safety of Foundation of building and response to earthquakes in rainwater harvesting areas apart from the improvement in vegetation density and pattern with overall heath of the vegetation.

RECOMMENDATIONS

1. The Rainwater Harvesting has been tested in Jamia campus and now The Rainwater Harvesting Master Plan must be developed for entire INDIA in a phased mannure begning with MOST NEEDY AREAS upto District, Tehsil, Block and Village level2. The Master Plan should have the coordination from Ministry of Water Resources, Urban Development, Rural Development, Agriculture, Human Resources, Panchayati Raj, Environment & Forest, Science & Technoogy and Local Development Authority with Jamia Millia Islamia3. The regular Training should be provided from the gross root level with Gram puchayat,Tehsildar, SDM, ADM, DM and local engineers and NGO’s4. The researches in the universities and must be shared with ministeries and should be made publich for their own area through websites and training.5. The regular monitoring must be put on the Website and Rainwater Master

Plan should be improved accordingly
