Getting the Most Out of Your Storage Basin: Optimization Strategies for Planning, Design, and Construction

摘要

This paper will describe the innovative concepts, methods, and tools used to optimize the design and performance of a wet weather storage facility located in a challenging environment. A 2.4 Million Gallon (MG) sub-surface storage facility, located in a park adjacent to Lift Station No. 2 (LS02) on the banks of the Root River in Racine, Wisconsin, was designed not only to meet the desired level of service (LOS), but also to serve as a flow-through system when the tank is full. This allows for primary treatment of overflows more than the desired LOS, while significantly improving the level of protection for nearby home owners against basement backups. The paper will step through project development based on a set of optimization criteria, including the reduction of sanitary sewer overflows (SSOs), reduction in basement backups, and enhanced treatment of SSOs. This criterion was applied throughout the planning, design, and construction phase of the storage facility to reduce cost and improve performance.
