EMH&T is a consulting engineering firm that provides a full range of civil engineering services including utility system design, bridge and highway design, residential planning, and commercial development. This paper describes work performed to develop a GIS to support sanitary sewer evaluation survey (SSES) studies. An SSES study aims at identifying infiltration and inflow (I/I) sources in a sanitary sewer system to plan and develop cost-effective system rehabilitation and maintenance activities. Working with the City of Columbus, we have designed and implemented an ArcView GIS-based GIS system to provide City engineers with the capability to access, query, and manipulate the data stored in the SSES database. The system also provides tools to easily generate SSES reports and to interactively visualize the spatial characteristics of the sewer system based on the SSES results.
