of Engineering, Pottapalayam, Sivagangai (Dist), Tamilnadu, India. Table.1 shows the Quality of the water stored in this reservoir, and Table.2 shows period during which rainwater was saved. Table.3 shows the Quantity of water collected in one year. The observation reports that in this plant almost all the rainwater falling on the fiber plastic sheets is collected. This is one way to collect rainwater without wastage. So this plant collects huge quantity of water even during small rain. Here rainwater is collected without bringing it in contact with the soil. So the collected water is colorless and odorless (table1). Therefore it is fit for drinking after simple filtrations. The observation reports that in this reservoir the average depth of evaporation per month is 0.152m (without roof) and 0.108m (with roof). During the observation period (one year) the collection bed and reservoir roof plastic fiber sheets withstand heavy solar radiation, high velocity winds and are also not damaged by any small animals like rats and rodents. So this project can withstand all kinds of natural disasters like lightning, fire and earthquakes. Therefore, lifetime of this project will be more. Since the proposed drinking water plant has longer operational lifetime, it is not only beneficial now but also for the posterity. As seen in this water plant model, Table.4&5 shows the quantity of water collected and supplied from this water plant, constructed from one acre to one thousand acres. From the observation, more water could be stored near small villages, big towns and cities using many plants of this project. Also this project can be implemented in any type of demographic region, be it arid, watershed or any other type. This project is easier to implement when compared with other projects like National River Interlink Project, Seawater Desalination Project etc. 3. OTHER APPLICATIONS • The water plant of this project can be used as one of the drinking water resources at villages and towns of dry countries. • The plastic fiber collection bed of this plant alone can increase the quantity of water and enhance the existing water resources. • This water plant, with some modifications, can provide copious water for agricultural and animal husbandry requirements. • The Water Plant could be constructed near forest areas for benefits of wild animals too. • All types of heavy industries can solve their water requirements with the help of water plants of this project. Same can be implemented at University, � � � 384 College, School, Hospital, Hostel and other Organizations as well. 4. OTHER FEATURES • While normal rainwater structures are meant to recharge ground water, this helps to collect water for immediate use. • The fiber plastic sheets have longer life as they are temperature resistant and even rodents could not damage them. • The depth of the reservoir can be maintained between 20ft to 30ft so as to save 80% of water from evaporation. • The usual tasteless rainwater is made tasty by the mixing of saline water in appropriate ratio. • Further, it could be protected from being polluted by animals through simple fencing. • Last but not the least, due to its techno-free working mechanism it is so called the “layman’s method”. CONCLUSIONS This paper projects that water scarcity related problems would be minimized with the installation of new water resources with fiber plastic bed land rainwater harvesting plants of this project. This project can be implemented in every country to meet its own water scarcity problems. It would give long term solutions too by enhancing both surface and ground water reserve table. This paper ensures that this project collects huge quantity of water and also the lifetime of this project will be more. The knowledge and the expertise available from the technical know-how of the project would help mankind live a life of plenty enjoying copious water availability. ACKNOWLEDGEMENTS The author acknowledges his debt of immense gratitude to the Principal and the Management of KLN College of Engineering, Pottapalayam, Madurai, India, who supported and offered the funds required for implementation of this project and offering sustained moral encouragement and inspiration in making the dream project not only a reality but as a success as well.

National Seminar on Rainwater Harvesting and Water Management 11-12 Nov. 2006, Nagpur 67. Approach to Rainwater Harvesting & Artificial Recharge using Remote Sensing and Geographic Information System A Case Study of Naini Watershed, Mahasamund District, Chhattisgarh State Introduction The natural resources like land and water are under tremendous pressure to meet the requirement of ever increasing population, which results in degradation of land as well as depletion of water table. The problem gets further aggravated due to vagaries of monsoon. Under this situation water conservation measures assumes great importance to achieve the objective of sustainable source of drinking water even in the event of persistent drought. Realising this situation the Government of Chhattisgarh, Public Health Engineering Department, conceptualized a project for statewide implementation of “Rainwater harvesting and *Shekhar D. Bhole **Anand P. Pradhan Abstract Realising the importance of watershed development for providing the sustainable source of drinking water, various state governments are implementing this programme on large scale. However in order to have realistic development plan a systematic study based on resources database is necessary. The situation calls for integration of database in GIS environment, which, facilitate identification of priority area as well as appropriate sites for construction of water conservation structures. The Govt. of Chhattisgarh has also taken up construction of water recharging structures on a large scale. Under the project ADCC Infocad has carried out studies in Mahasamund district. A case study of Naini watershed in Mahasamund district is presented in detail in the following papers. A sound resources database using remote sensing and GIS technique has been generated to understand the resources situation which was then followed by critical analysis of ground water scenario to arrive at identification of appropriate site for construction of water conservation structure. A detailed Engineering survey was carried out for preparation of cost estimate of recommended measures. Based on the study water conservation structures for Naini watershed has been suggested. The paper deals with study carried out for Naini watershed. 385 artificial recharge on watershed basis”. The Public Heath Engineering Department, Govt. of Chhattisgarh awarded a project of preparation of Draft Project Report of construction of water conservation measures in Mahasamund district. In accordance with the objectives of the project Naini watershed of Mahasamund Assembly Constituency from Mahasamund district has been identified for preparation of implement able action plan for rainwater Harvesting and Artificial Recharge. Study Area The Naini watershed is located in the east bank of River Mahanadi and stretched between *Director (Technical) **Manager ADCC Infocad Pvt.
