Abstract : A major problem affecting deteriorated Army wastewater collection systems is infiltration-water leaking into the system through cracks in system pipes, manholes, or building laterals. Another substantial problem is inflow, in which relatively pure water is deliberately diverted to the sanitary sewer system through mechanisms such as connecting roof or basement drains. Both types of extraneous water sources are grouped as one variable, commonly referred to as infiltration/inflow (I/I). Installation Directorate of Public Works (DPW) personnel need to be familiar with the causes and effects of I/I, as well as techniques for its mitigation. In terms of money and disruption of installation activity, the cost of replacing sewer systems is very high. The objectives of this research were to develop a logical, systematic sewer evaluation procedure for identifying I/I problems, and to develop a computer-based tool that will help DPW personnel analyze I/I data and enhance their decision making capabilities. This report summarizes techniques for gathering I/I data through field investigation, illustrates how to use that data in SIMMS-IIC, provides an overview of SIMMS-IIC, and discusses techniques for I/I control and mitigation, and other sewer system management Issues.
