Leakage of groundwater and rainwater into collection systems (I/I & RDI/I) is the # 1 problem that steals capacity, promotes sewer deterioration and wastes money every day for municipalities. This graph shows the successful reduction of I/I in basin E-11 in Brentwood, TN. The reduction is confirmed by the results of before-after flow monitoring. Flow monitoring is a critical component of an successful I/I reduction program. It is used to:
- target the problem areas,
- define and quantify the baseline I/I conditions, and
- verify the reduction of I/I following rehabilitation work
