Sanitary sewer overflows (SSO) are becoming of increasing concern to utilities and regulators. The number and severity of SSOs can be reduced by the detection-correction of ongoing events. A methodology is presented to locate meters to maximize the likelihood of detecting system blockages and SSO disruptions. The problem is solved using a set-covering approach and allows the trade-off between the number of detections and the cost of gages to be easily assessed. To introduce blockages and analyze system hydraulics, a full hydraulic model for the sewer system is applied. A system in Pima County Arizona is used as a case study.
