This paper describes the Flow Balance Method (FBM) used to control a Combined Sewer Overflow (CSO) and a statistically based performance evaluation for the system. The FBM uses containment within a receiving water body to store CSO followed by pumpback to the wastewater treatment plant (WWTP). The performance evaluation uses a mass balance incorporating specific conductivity, measured flow rates and their probability distributions in a Monte Carlo program to calculate probable volumes of sea water in the pumpback and hence efficiency of the system. Important aspects of this analysis for the subsequent expansion and monitoring of the second phase FBM demonstration included: confirmation of the reliability of specific conductivity to indicate the volume of sea water in the pumpback; an indication of the sensitivity of the predicted performance to variation in the parameter values used; and therefore identification of the relative importance of the different data distributions to allow more effective data collection in the second project phase.
