Bureau of Watershed Protection
InterJurisdictional Flow Monitoring

The inter-jurisdictional flow monitoring section is responsible for generating the data that is used for billing surrounding municipalities that have entered into contractual agreements with the City of Atlanta for treatment of their wastewater. Currently, Atlanta has contractual agreements with the following jurisdictions: East Point, College Park, Hapeville, Clayton County, DeKalb County, Cobb County and Fulton County. As an example of the data produced by the flow monitoring section, DeKalb County and Fulton County combined contribute approximately 52% of the flow received at the R.M Clayton Water Reclamation Center. This data is used to recover costs incurred for operations, maintenance and repair of facilities. These costs currently average over $15 million per year billable to Atlanta’s inter-jurisdictional partners.

Atlanta uses state-of-the-art flow monitoring equipment and communications technology. Wherever possible, the City uses solar panels to provide electricity to power these sites and cellular modems for communication.

The City of Atlanta is also required to install and maintain rain gauges in each of the CSO areas. These rain gauges are installed, maintained and repaired by the IJ flow monitoring program. Data reports are generated on a monthly basis and are used in the CSO monthly operating reports.
