In response to growing public awareness of water quality issues and public demand for water quality information, in 2006 the Madison Water Utility sought an innovative solution to maintain a high level of customer service while minimizing the efforts required to provide water quality information to individuals. An all-pipes distribution system model was used to identify the source of supply mixture, or zone of influence, for each of the 24 wells within the service area. GIS techniques were utilized to associate the hydraulic model output with all customer service addresses and this information was organized into a database to be employed by the utility. This poster paper presents the result, a web-based address lookup system that allowed the public to view the source of supply mixture at their location and provided dynamic links to water quality information delivered only for the specific wells that served the individual. As a beneficial byproduct of the process used to review the accuracy of the database results, figures were created illustrating the zone of influence for each well within the distribution system. These figures have since been used by utility staff to aid in the identification of candidate flushing locations in events of water quality impacts at particular wells.
