Pinellas County is the second smallest and most densely populated county in Florida. The Pinellas County Utilities (PCU) encompasses the County's water system, sewer system, reclaimed water system, solid waste operations and recycling. This paper discusses the implementation of a geographic information system (GIS) for the County's water, sewer and reclaimed water systems. Development of the GIS involved building a composite description of PCU that is used for decisionmaking purposes. The GIS is used for three primary purposes: infrastructure management; map and database publishing; and, business applications. Includes figures.
