To develop new ways of Waste water management system in rural areas

Abstract : This study has been undertaken to develop Sustainable Waste Water treatment. Most of the river basins in India and elsewhere are closing or closed and experiencing moderate to severe water shortages, brought on by the simultaneous effects of agricultural growth, industrialization and urbanization. Current and future fresh water demand could be met by enhancing water use efficiency and demand management. An estimated 38354 million liters per day (MLD) sewage is generated in major cities of India, but the sewage treatment capacity is only of 11786 MLD. Similarly, only 60% of industrial waste water, mostly large scale industries, is treated. . The scope of this paper is to provide some easy-to-understand guidance on taking decisions in wastewater management in settlements and towns (waste stabilization ponds, HSSF_CW, DEWATS) with up to 10,000 population equivalents (PE).
 ? Due to existing regulations, plant volumetric capacity decides the treatment technology. ? Much delay exists in wastewater management in rural areas, where construction of centralized WWTP is considered too expensive. ? Its robustness and vulnerability towards power cuts, water shortages, floods, etc., and flexibility/adaptability to existing infrastructure and demographic or socio-economic developments are also important aspects.
 ? The discharge of waste into water courses led to gross pollution and health problems for downstream users. ? Treatment of wastewater became apparent only after the assimilative capacity of the water bodies was exceeded and health problems became intolerable. ? Its disadvantages however include odour problems and it requires a large area of land to function properly.
 • The proposed methodology is developed in three different stages and is applied to a pilot basin for the purpose of validating the results for the design of a model of general application. • This study is proposed the definition of a Support System for decision making which must meet a number of conditions on the geometry of the system and the mathematical structure. • The purpose of the model is the maximizing of the minimum distance between installations and the centres of the closer core.
 ? The excess solids and organisms are removed from the system (waste activated sludge) to enhance the performance of the system. ? There are conventional and non-conventional wastewater treatment methods which have been proven and found to be efficient in the treatment of wastewater. ? The precautionary and the polluter-pays principles which prevent or reduce pollution to the wastewater have proven to be very efficient in the industrialized countries and should be adapted in developing countries as well.
