SAN FRANCISCO CSO

Design and construction of the Islais Creek transport/storage facility is highlighted in this article, which explains the current problems in San Francisco's combined-sewer-overflow (CSO) system. Light rains, particularly in the Islais Creek Basin area, send untreated sewage and storm water into the bay and Pacific Ocean because of limited capacity. San Francisco is solving the problem with a 1,448-km (900-mi) long CSO control system that will consist of a series of underground reinforced concrete box sewers, tunnels, pipes, and pumping stations to store the combined sewage until it can be pumped to a treatment plant. Full-face tunnel excavation will require extensive jet grouting, which is described in detail.
