A Practical Guide — Planning Considerations for Mega Dollar CSO Projects
Abstract:Tunnels are a practical solution for storing large volumes of combined sewer overflow (CSO) with limited surface disruption during construction. Careful consideration during the evaluation and preliminary design phase of the project can help to mitigate risk and potential pitfalls during detailed design and construction. Early planning in the preliminary design phases can reap great project rewards, cost less, and lower risk during construction. This paper presents the principal elements for the development, preliminary design, and constructability considerations of a CSO storage and conveyance tunnel project. Information presented includes the evaluation of the geology and hydrogeology of the tunnel alignment corridor, construction considerations, project considerations, geotechnical exploration program, risk management strategies, and conclusions. Information is included in this paper for the Fall Creek/White River Tunnel Evaluation project, as it pertains to the types of considerations that should be completed during preliminary project phases of a storage tunnel project.
