USING INFLATABLE DAMS FOR CSO CONTROL

The paper describes in detail the design and construction of in-line storage systems using inflatable rubber dams for combined sewer overflow control. The materials of construction, information needed for design, major equipment required, instrumentation and control options, and installation procedures for a typical inflatable dam system are discussed. This is followed by a description of the design of three in-line storage systems for the City of Indianapolis, Indiana. The information that should be obtained during the pre-design and detailed design phases is detailed. The equipment used to operate the dams and the instrumentation and control system are described. Finally, the lessons learned during the construction phase are discussed.
