Wastewater collection system on military installations require periodic maintenance and repair, and occasionally upgrading. Deterioration of wastewater systems enables the entry of extraneous water (termed Infiltration and Inflow or I/I) into sanitary sewer collection systems. This imposes a significant problem by overloading the both the wastewater collection system and treatment plants reducing the capacity and capability of sewer systems to transport and treat domestic and industrial wastewaters. Proper selection of rehabilitation techniques and allocation of repair dollars in the most cost-effective manner is a problem for utility personnel. Therefore, USACERL initiated a research project to mitigate I/I problems in US Army installations' sewer systems. A standard procedure for sewer system evaluation was formulated along with a software package designed specifically for Army I/I studies and applications. The U.S. Army Construction Engineering Research Laboratories (USACERL), working with Planning & Development Applications (Belmot, MA), developed a dynamic infrastructure management tool called the Sewer Inventory and Maintenance Management System for Infiltration and Inflow Control (SIMMS-IIC). Data is entered into SIMMS-IIC and processed and the effectiveness of each can be compared until an optimal solution is found. Demonstrations for the software capabilities were conducted at a Southern US installation to introduce it to the user community. Discussions of USACERL experience with the project, applicability and benefits to municipal and private systems, and particular user input for the program will be part of the project presentation.
