Résumé partiel
Water resources are national assets. Mismanagement and unplanned development of water resources have resulted into water crisis in our country Poor water availability becomes a severe constraint in food production, economic development and protection of natural systems. According to National Water Policy, water is a precious national resource to be planned, developed and conserved in an integrated and environmentally sustainable manner, keeping in view the needs of the states concerned The futuristic demand of water resources for irrigation will be highly critical considering present scenario of withdrawals of surface water and ground water. The scarce surface water resources cause decrease in annual intensity of irrigation and thereby cause loss m economy due to insufficient agricultural production It is observed that excessive pumping of ground water for irrigation will cause decline in water table and results in decrease of ground water storage. If such trend continues, then it will cause undesirable mining of ground water, which is considered to be against the conservation standpoint. In such crucial and critical situations, it is required to investigate alternate sources of water for irrigation e.g municipal sewage with a view to conserve surface water and ground water resources It is observed that problems related to disposal of sewage increase with increase in population of city. An increase in population leads to rise in pollution load on natural water bodies Under the above circumstances, the use of sewage water for irrigation also paves way for efficient disposal of sewage i e domestic wastewater, which in turn has become bane for many municipalities and local bodies.
