Taking Control of Your Data: Sewer Flow and Rain Monitoring System Reorganization, Expansion and Upgrade

The expansion of the City of Atlanta, Georgia sewer flow monitoring program started with a 1998 federal consent order to overhaul their sewer collection and CSO treatment systems. The number of inter-jurisdictional (IJ) flow sites increased from 20 to 90 with 140 temporary flow sites and 34 rain gauges. To meet the consent order, the temporary sites and rain gauges were installed and managed by a private contractor. A decision was made to take over the temporary sites and rain gauges. An audit of existing sites was performed to determine equipment and staffing needs. Additional people were transferred or hired, and then trained by our vendor. The contractor's metering equipment was replaced with our standard meters. Ten years of historical proprietary data was reformatted and merged into our database. An equipment database was created with an intranet web interface for managing the meter maintenance.
