San Francisco needs to repair a critical 19-mile stretch of pipe bringing water to the Bay Area from Hetch Hetchey. The pipe is at risk of collapsing. The pipes also carry the main supply of water for the hydroelectric powerhouse for the city.
However, the San Francisco Public Utilities Commission is struggling financially and it’s hard to see where the needed $625 million needed for the repairs will come from. They are in the red already.
There are also only two to three months a year that the work could be done, because at other times the pipes couldn’t be taken offline without a shortage resulting.
If the 19-mile tunnel failed San Francisco could be cut off from this water supply for up to nine months. Several solutions are being considered.
