A. BACKGROUND

Seminole County (The County) has owned and operated water and wastewater utilities since 1975 when it acquired the Indian Hills and Consumer investor-owned utility systems. Since then, The County has acquired additional systems through purchases and bankruptcy proceedings, and The County has increased its customer base through new commercial residential developments. As of December 2023, Table 1 shows that Seminole County had the following equivalent residential connections (ERCs):

The County's utility system is divided into four geographical service areas: Southeast, Southwest, Northeast, and Northwest. These areas include a number of subsystems corresponding to water distribution/wastewater collection/reclaim water distribution systems served either by County-owned facilities or through wholesale purchase agreements with other utilities. The system serves an aggregate geographic area of approximately 27 percent of the County's 345 square mile area.

The County’s system is comprised approximately 644 miles of water distribution, 178 miles of sewers, 101 miles of wastewater force main and 350 wastewater pump stations.
