The study was conducted to investigate the ecological effectiveness and economicefficiency of four wastewater treatment plants in East Central Indiana (Muncie, Anderson, Alexandria, and Paws). Data were collected from the four plants, then analyzed descriptively and statistically, and compared in terms of ecological effectiveness and economic efficiency. The Muncie, Anderson, and Paws wastewater treatment facilities were not significantly different from one another in terms of biochemical oxygen demand (BOD5) reductions, but each reduced BOD5 more than the Alexandria facility over the three- year period (1996, 1997, and 1998). Plants were not statistically different regarding suspended solids (SS) reductions. The Muncie, Anderson, and Paws wastewater treatment plants were also not significantly different from one another on ammonia reduction, but each plant reduced ammonia significantly more than Alexandria. Muncie and Anderson were not different from each other on dissolved oxygen (DO) levels, but each had a statistically higher level of DO in the final effluent than Alexandria and Paws. The study showed a statistically significant difference in fecal coliform bacteria abatement between Anderson and Alexandria, Anderson and Paws, and Muncie and Alexandria. Furthermore, Muncie, Anderson and Alexandria were different in terms of cost per 1000 gallons of wastewater treated. Muncie has been treating wastewater at a lower cost than the other treatment plants, whereas Anderson had a higher cost over the three-year period. / Department of Natural Resources and Environmental Management

This project explains the differences in available financing techniques for wastewater treatment plants and sewers and describes the experiences of Indiana communities that have used the various techniques. The results of the study are presented in a form that other communities can use to make informed fiscal and administrative decisions. While both the traditional and new financing techniques can be used to pay for the needed wastewater improvements of a community, they are not interchangeable. These techniques differ along legal, political, administrative and fiscal lines. Not all techniques are legally available to Indiana communities. Those that are available differ in the ways that they are established, work and provide funds. Individual communities also vary in their experiences with these techniques. Indiana communities need to understand these different financing techniques if they are going to address the problems of wastewater financing.This project examines the new financing methods and loan and grant programs that are now available for communities to finance needed infrastructure improvements. Not all of these methods are available to or appropriate for every community.Communities need to understand how these programs differ and the issues involved with each one. While this thesis can not be a substitute for the advice of an attorney, grant writer, accountant or engineer, it can provide valuable information to local officials. By understanding how these methods work and knowing about the experiences of communities that have used them, other communities can make informed decisions. / Department of Urban Planning
