Project Goal

Design, implement, and support an effective Enterprise GIS in a large wastewater management agency. This has been accomplished through appropriate software deployment and user training in nearly all areas of the agency: information technology (IT), engineering, plant operations and maintenance, wastewater collections, commercial and industrial monitoring, and ocean monitoring. Through the training and use of GIS web services, ArcGIS Desktop, and mobile GPS/GIS, users in these functional areas have effectively performed GIS activities for the past two-and-one-half years.

Business Problem Solved

Prior to taking an enterprise approach, the organization was not fully realizing the benefits of GIS. After staffing IT to a level sufficient to serve the agency, a broader view of agency-wide needs was achieved. For the past two-and-one-half years, GIS has been centrally managed. GIS needs are considered, analyzed, and staged for implementation at appropriate times. The program schedule considers tactical and strategic needs: the tactical addresses short-term necessities, with the strategic view in mind for user needs, data availability, system compatibility, and program administration. An example of this approach is the near-future integration of a mature information silo, the Computerized Maintenance Management System, with the Enterprise GIS via GIS web services. By contrast, Enterprise GIS will wait to integrate a less mature complaint management database, instead allowing select users in the agency join and analyze complaint data from various data files to geography within ArcView.
