So San Francisco doesn’t go thirsty
05 August, 2010
Like most infrastructure in the San Francisco area, the Crystal Springs By-pass Pipeline can be affected by seismic activity, so the risk assessment of its design, safety and functionality has to take this into consideration. It was decided that the risk, from landslide damage to the pipeline in particular, was too high to rely on the original structure, so an alternative by-pass tunnel was decided upon as just one, but a vital, part of the Water Supply Improvement Progam (WSIP) undertaken by the San Francisco Public Utilities Commission (SFPUC). Maurice Jones reports on its completion.
