A local Siemens representative was visiting a construction site for a new water/wastewater treatment plant in the Southeast United States. Recent growth in the local housing market near an EPA wetlands area required the installation of a new package treatment plant. Discharge permits for this new plant would require continuous flow monitoring and strict discharge levels for chlorine residual. The accuracy and reliability of the level/flow measurement and chemical feed control system was critical. The discharge flume from the wastewater treatment plant would be approximately 50 ft. from the wetlands buffer zone.
