An involvement of human awareness in the process of decision making implies great complexity in acceptability of Sewage Treatment Plant (STP) on the basis of environmental quality of receiving water bodies. Social environment, physical surrounding and economic constraints have an effect over complex human perception. An importance of pollution parameters in determining an acceptability of STP has a major bearing on the human decisions. Both the decision processes are complex with higher degree of subjectivity involved and therefore call for the analytical computing tools which can imitate the behaviour and bring the results close to the reality. A treated sewage from STPs isgenerally disposed in water bodies without considering Environmental Quality, which promotes degradation of quality of water bodies. An attempt has been made to formulate Fuzzy Rule Based System (FRBS) for an environmental acceptability of STPs, based on their water pollution potential and Environmental Quality of water body. An Environmental acceptability with degree of certainty of these STP has calculated to justify the quality of treated sewage as one value by considering all parameters. A case study of Sewage Treatment Plants which are located in the vicinity of Pimpri, Pune, Maharashtra, India is also incorporated in this study.
