The 5.0 million gallon per day (MGD) Coneross Creek Wastewater Treatment Facility began operations on February 4, 1980. The original treatment plant was upgraded to 7.8 MGD in 1996 in order to accommodate the industrial and commercial growth Oconee County experienced during the early 1990s. Along with the treatment plant, the OJRSA also owns, operates, and maintains a wastewater conveyance system that includes approximately 65 miles of gravity sewer, 15 pump stations, 24 miles of force mains, and three permanent flow monitoring stations.
