The United States and the European Union each have their own policy approach to protect surface water quality. Both policy approaches are similar in many ways. Both rely heavily on command and control. However, there are differences in the application of the details. Both the U.S. and E.U. began current efforts to protect surface water quality in the 1970s, yet quality continues to less than desired in both places. Both have reduced point source pollutants but have had difficulty controlling non-point source pollutants even though policies have been in place for many decades. The successes and failures of the two policies are studied in this project to determine which aspects of both policies will best protect surface water quality in an increasingly complex future.

As the population of Colorado continues to grow, the impacts from individual sewage disposal systems, or onsite wastewater systems (OWS), are becoming more apparent. Increased use of OWS impacts not only water quality but land use and development as well. These impacts have led to the need for a new generation of wastewater regulations in the state, a transition from the historic prescriptive requirements to a more progressive, performance-based system. A performance-based system will allow smarter growth, improved water quality, and cost savings for both the regulatory agencies and the OWS industry in Colorado. This project outlines the challenges and essential elements required to make this transition, and provides guidance on how to meet the challenges and overcome barriers to implementing a performance code in Colorado.
