"Symphony - Harmonious pump & flow management" is a patent-pending technology that is available only from Data Flow Systems, Inc. (DFS). Symphony utilizes SCADA to coordinate the system-wide operation of sewer lift stations for the purpose of reducing force main pressures and equalizing flow into a wastewater treatment plant. The result is a significant reduction in energy costs and a solution to daily peak-flow problems.

Symphony requires the use of DFS' Hyper SCADA Server (base station) and the TAC Pack TCU (pump-controller RTU) at each lift station. A combination of functions provided by both the Hyper SCADA Server and TAC Pack TCU are utilized by Symphony.

Pump Management: In this facet, Symphony is essentially a coordinator that addresses the random asynchronous operation of each lift station operating on a common force main. Symphony synchronizes the pumping activity on a minute-by-minute basis. Head pressures are reduced and pumps begin to operate more effectively and efficiently. The results are diminished pump-run-times, less maintenance costs, and a reduction in pump energy expenses potentially 30% or more!

Flow Management: Peak-flow problems occur in a collection system several times a day. There are opportunities to reduce peak flow in virtually every collection system. Symphony employs a technique that levels the flow by systematically managing the peaks and valleys over a 24 hour period. Overflows at the head-works can be prevented, the need for equalization basins may be eliminated and the biological treatment systems work more efficiently.
