The Snapfinger Wastewater Treatment Plant in south central DeKalb County operates above 80 percent capacity during periods of intense storms. This is due to intrusion of stormwater into the sanitary sewer system, therefore the county has instituted a program to decrease flows by reducing infiltration and inflow (I&I) of rainwater and groundwater into the system. Construction of a 20 million gallon surge tank was completed in January 2003. The tank allows equalization of flows to and through the plant. The total project cost was $6.9 million.
