ABSTRACT
Due to rapid growth in cities, the demand for water has increased tremendously. To meet the demand of water, the groundwater resources are been tapped at such a rate that they are depleting at a very fast rate. Secondly, there has been no adequate recharge of groundwater resources to maintain the continuous supply of groundwater. Thus, we have to see that the water resources already present are maintained and also they can be increased by some other options. Therefore the water resources have to be maintained and managed well. The future of our water resources depends upon the development of water resources. Thus, reuse of water has become the need of the hour. One of the options could be the use of treated wastewater effluents. Towns and cities generate huge quantities of sewage. This, when discharged directly onto open grounds is causing considerable pollution of water, soil and air. The sewage may first have to be treated in sewage treatment plants, which in turn will yield great quantities of effluents. The problem is how to make good use of effluents, which not only go waste, but also cause environmental pollution. Now, the question is, by what means the effluents from sewage treatment plants can be turned into reasonably pure water. Soil has been known as a greater cleanser of water. It has the capacity of acting as a physical, chemical and biological filter. Can such a commonly available and inexpensive agent be used to convert the effluents from sewage into normal water? That is the great task that lies before us in tackling the national problem of water scarcity
