HYDRAULIC CONDITION ASSESSMENT
Combating excessive infiltration and inflow of (I/I) in separate sanitary sewer systems has long been a frustrating, unrewarding process for many municipalities. Conducting I/I studies and sewer system evaluation surveys (SSES) and subsequent maintenance and rehabilitation efforts to control I/I, only to see little reduction or even an increase in I/I is no public works manager's idea of money well spent. Some municipalities have even abandoned trying to locate sources of I/I, opting instead to systematically rehabilitate entire sections of their system. Other municipalities have given up trying to reduce I/I and have elected to simply increase their pump stations, interceptors, and treatment facilities instead.
