Introduction To MJSA & Four Waters Interventions Prologue From Water Resources perspective the Rajasthan state is critically placed. There persist huge gap between genuine requirement and availability. Ever growing population, urbanization and demographic transformations are exerting tremendous pressure even in addressing the basic for drinking and domestic use. For the state, water has been the utmost scarce and precious natural element. Contd------ More than 45.00 % of total surface water available to the state is borrowed from neighboring states. On the contrary , surface water resources available within the State have not been exploited to optimum level, hitherto. Owing to indiscriminate extraction, the state of ground water too is extremely critical and alarming.
Minor & Micro Interventions To address / pacify water scarcity scenario two flagship programmes were initiated involving minor & micro interventions . 1. Four Waters Concept based executions. 2. Mukhya Mantri Jal Sawavlamban Abhiyan (MJSA). In fact, both are complimentary to each other . The Four Waters Concept intervention address the supply side only whilst, under Essence of Four Waters Concept Renowned Engineer and United Nations Consultant Late Sh. T. Hanumanta Rao was not only the propounder of the concept rather, had done pioneering work in this field.
The term Four Waters implies for (i) Rain Water,(ii)surface water, (iii) ground water, (iv) soil moistures. Its an unique intervention envisaged for Integrated Catchment vis-a-vis command area development coupled with consequential benefits viz:- tremendous boost in Ground Water recharge/ Contd------- averting intervention, soil conservation, enrichment of soil moisture, ensuring water availability for community use, sustaining lively status of rivers and streams for longer duration in post monsoon era, development of flora and fauna thereby adding and sustaining bio diversity and eco system at large, for the benefit of mankind. As of now, the four water concept
intervention is being implemented in surplus segments of Chambal, Mahi, Luni, Sukhli, Sabramati, Parbati, Banas river basins engulfing 12 districts of the state. Strategy of Four Waters Concept Implementation In the initial reaches of catchment area involving first and second order streams, well planned and scientifically designed extensive water shed development activities . It will give tremendous boost to ground water recharge depending upon the underneath hydrogeological formations and aquifer status. It shall also retard and prevent soil erosion and help reducing turbidity level by arresting silt, to a cognizable extent besides enrichment of soil moisture. In the valley portion across third order stream onwards, micro irrigation / minor storage tanks are constructed to facilitate arrest of spring flow emerging out owing to extensive catchment area treatment venture undertaken in upper reaches and to harness precipitation runoff. For multi Contd------Depending upon technical feasibility and viability small check dams (up to 2 m. height) are raised in the downstream of
MIT/ MST. Streams and nallahs amalgamates into local river. Series of Barrages/ Anicuts are proposed to be raised across local river to facilitate impounding of monsoon flow all through out the river tract. This help transforming seasonal stream /spring into perennial or semi perennial. ckn y Ok"k kZty Ok"kk Zty igk M cSj kt un h Lh0lh0 Vh0 Hkwfe

A unique campaign launched by the Honble Chief Minister to render villages self reliant in catering minimum water requirement at village level, in phased manner. The paramount features of MJSA:Concerted and co-ordinated approach of all stake holders and government organs working in the field of water resources management( supply & demand sides, both) is ensured. Total and thorough involvement of all stack holders and ultimate beneficiaries right from planning to execution and utilisation Stage. To ensure and achieve this, vigorous, IEC Contd -----For mass awakening, besides IEC campaign, sincere involvement of social and religious groups was ensured. Besides budgetary support from govt. exchequer, assistance from corporate sector, religious institutions, NGOS and common men was sought. Involvement of all peoples representatives in hierarchy, secretaries to govt, revenue and development administration is integral part of campaign. Organising vigorous trainings, workshops seminars and talks for all concerns to appraise
and educate them of concept vis-a-vis approach to establish parity and purpose worthiness. Modus Operandi-MJSA Micro Watershed based planning was adhered upon. Villages engulfed in the ambit of micro watershed constituted the cluster. Cluster wise D.P.R was prepared conceding cognizance to each village of the cluster. The size of micro watershed was kept in vicinity of 5000Ha. Albeit, a revenue village was considered basic unit, yet cluster based planning was adopted. All stake holders including locals and beneficiaries were brought on to one platform under aegis of district collector to conduct Contd----Minimum water requirement was calculated, followed by assessment of availability from existing sources. Assessment of deficit and contemplating interventions to bridge deficit, preferably locally else, from distant sources from within
clusters or outside cluster, as the case maybe was done. Emphasis is on:Planning, design and estimation for rejuvenation & renovation of existing sources. Water shed development activities to boost extensive ground water recharge. Creation of micro and mini sources / storage Water Contd---- conservation measures:Affecting water economy, emphatically in agriculture and horticulture use. Motivation towards resorting to innovative and scientific culture & practices for Irrigation. An exclusive Website was launched on which exhaustive details of DPRs are available . For monitoring and evaluation a specific software is developed . Geo-tagging of all the works is done to facilitate uploading day to day progress and photographs directly from field through mobile application emphatically crafted for this cause.
Funding:Conglomeration of host of Governmental programmes/Schemes, united fund, donation & assistance received from Achievements of MJSA Phase-I Project cost MJSA Phase-I- Rs 1714.25 Crore Expenditure till date Rs 1525.13 Crore The first phase of MJSA involving 3529 villages has almost been completed . Attempt to rendering villages of project area self reliant in the context of basic minimum water needs. Enhancement in ground water recharge and replenishment. Reduction in, soil erosion and consequently in the turbidity level of flowing water. Gradual transformation in agriculture and practices.
