Bucket/ Mug 50 Ltr 200-250Ltr availability of resources ,Human, Technical ,and Financial are important for that .Major cause of the floods and draught in the area like Balaghat which is paddy growing area is that due to traditional knowledge and practice, all the fields filled with water for crop, in this process the whole area of agriculture convert in a kind of blockage which don’t allow water to absorb in the mansoon which ultimately create draught in summer. Some of the recommendations are as follows : 1. All the data available at government, non government Academic and Research institutions should be compiled and made available to everybody on internet. 2. All the latest Rainwater harvesting techniques should be compiled and made available to all interested individual and institutions from panchayat to national level. 3. All the works from traditional knowledge to the latest one should be collected and made available to everybody. 4. This is a work which needs involvement of everybody at every level so the planning, Execution, media should also come together and work with target and result oriented strategy. 5. Develop some systematic plan with the help and guidance of planning commission to suit every body and every sector. 6. formation of high power committees from National to village level with the involvement of every sector. 7. All the Government, Nongovernment, Panchayat, Cooperatives, Media, Technical institutions should be the members of this committee. 8. proper feed back systems are very essential for the monitoring and follow up. 9. Near railway lines, Roadsides, canals plantation work should be encouraged. 10. Some special Award can be launched for proper implementation, as this is very positive way to recognize for their outstanding works in the field. 11. All the Panchayats should be involved to take necessary works related rainwater harvesting these grass root agencies are very effective for such works. When rahim says these words in the year — — there were no water scarcity, nor water was polluted, even at that time he was well aware, that the gift of nature is how precious, for the existence of the planet which believes that there is only earth, where the life is, we can see how limited the availability of water, which we are using without even thinking, about the fact that this can not be produced in any factory, except through the nature itself, we hardly feel its importance, however whenever there is a scarcity of water we realize how useful it is in our day-to-day life ,apart from our daily use ,we depend on water, to fulfill our other requirements ,A large amount of water is used in agriculture, to produce food, also industries use water, to carry out various processes ,increasing demand of electricity is also needs water Although the earth has a huge stock of water, the amount of water that can be used by human beings and other animals is very small. The figure shows about the availability of fresh water —as per diagram shown below——of the total water available on earth, 97.40%is in the oceans. Due to its salinity it cannot be used by human beings most of the fresh water is frozen in the polar. � � � 456
National Seminar on Rainwater Harvesting and Water Management 11-12 Nov. 2006, Nagpur 81. Public Awareness on Rain Water Harvesting - A Case Study in Chennai City GENERAL Water is life and blood of our environment and without water no living being can survive. Water is finite resource and cannot be replaced/duplicated and produced on commercial scale. Ground water is the largest reservoir of fresh water on the planet. It immensely contributes to India’s development and economy. It meets 85% of drinking water needs of rural India. It sustains 60% of irrigated agriculture and plays an important role in social equity and poverty reduction. The phenomenon of human induced ground water extraction due to excessive development led * A. Jebamalar **Dr. G. Ravikumar ABSTRACT Any initiative involving the public in a mass scale will be successful only when the public themselves are consulted and are participating in every process. As the stakeholders, their involvement has been necessitated, in the recent times, in any water related initiative. This paper attempts to bring out the importance of public awareness in the implementation of rain water harvesting. Government, though it represents the public, may not be in a position to deal with such water related issues out and out by itself. Understanding this, Tamil Nadu Government made rain water harvesting (RWH) as mandatory by the public. This paper focuses on public awareness for RWH implementation in Padmavathi Nagar of Chennai City. A nondisquised structured questionnaire was prepared in Tamil & English and the questionnaire survey was conducted at 38 households of the study area. It is a 5 page questionnaire contains three major parts. The first part is about general information regarding the resident’s personal details, No. of persons in the family, area of the premises, soil details, awareness about RWH system and their willingness towards this survey. The second part contains water resources engineering aspects, with water availability, water usage, quality of water and the sufficiency of the available water at their premises. The third part contains the details of the RWH systems like type of the system, features and their opinion about the RWH systems. Coding sheet was prepared and the information like awareness about RWH system, its purpose & its impact, willingness to conduct study and their opinion about RWH were studied. This will help to study the involvement of the public in implementing RWH system. to decline in ground water level, resulting in water scarcity in some areas. There are a lot of impacts associated with falling water levels such as sea water intrusion, land subsidence, depletion of surface water, high pumping cost, etc. So, ground water resources should be managed in such a way that the recharge is kept at pace with the with drawls through artificial recharge of rain water. Hence, artificial recharging of ground water by Rain Water Harvesting is the solution to improve ground water potential in order to maintain the sustainable water resource. *Sr.lecturer, Velammal Engg.
