Enterprise Geodatabase Implementation for a Large Wastewater Collection System Track: Water, Wastewater, and Stormwater Author(s): Gilbert Osei-Kwadwo, Greg Thomas, Edward Langdon Fairfax County Wastewater Management (WWM) provides sanitary sewer services to about 88 percent of the 1 million residents in Northern Virginia through a system of more than 3,300 miles of sewer lines, 88,000 manholes, 61 pumping stations, and 51 metering stations. Over the last several years, WWM has built a very effective GIS infrastructure for this large system based on ArcInfo coverage data format. WWM recently converted its coverage data into Enterprise geodatabase and created a geometric network for the system. This paper will give an overview of the migration from coverage to geodatabase and the creation of the geometric network, lessons learned and still learning during the process, potential future uses of the data in the new data format, and cost and time savings in data capture and analysis. Finally, it will also highlight how this new data format has made the update and maintenance of this large system easier through versioning.
