a debate is emerging between the San Francisco Public Utilities Commission (PUC) and the Bay Area Water Supply and Conservation Agency over the potential disaster if the 89-year-old Mountain Tunnel, which supplies 2.6 million Bay Area homes and businesses with water, collapses.
The PUC acknowledges that the tunnel does have a chance of "catastrophic collapse," which would require repairs costing $100 million or total replacement, costing up to $630 million. But the PUC’s 10-year-old 4.6 billion water system improvement program did not include the Mountain Tunnel in its plans.
...
The risk right now is that the tunnel lining could continue to fail and, at some point, that might restrict our ability to get flow through it. That would be catastrophic to us -- any rapid failure that results in the reduction of water flow by 25 percent. That's a big deal.
...
Nicole Sandkulla, the Bay Area Water Supply and Conservation Agency’s general manager, asserted that she had joined others to warn the PUC to look into potential problems with the tunnel, and they were upset when it "fell off that list."
In January, Sandkulla wrote the PUC "about the surprising and alarming notice we received... that the Mountain Tunnel, a vital part of the San Francisco Regional Water System, is at serious risk of a catastrophic collapse, which could cut off, for months, 85 percent of the water needed by residents, businesses, and community agencies in the Bay Area."

MY GOD!!!!!!!!!
If they lose their water what’s going to happen to the bath houses?
On second thought, they don’t really take showers in them anyway.....forget it.
At least for ten years or so until a new tunnel could be built.
The whole thing just might be cancelled due to the discovery of the wooly maggot or the 8 toed grasshopper.
“Supplying water to cities and population centers is ancient technology. Over 2000 years ago the Romans built hundreds of miles of aqueducts.
After the fall of Rome no one built another one for a thousand years. “
I watched a Roman Empire video last week which showed at the end of the Empire a barbarian army attacked and disabled the last aqueduct feeding the city. After that the city population fell to less than 1000 people.
Debate = who gets $$$
I guess the enviros would consider it was damned by being dammed.
Won’t work. There is to much heat required to set the material. Mountain Tunnel is 18.3 miles long and 10 foot in diameter.
In their parlance, it would be "bourgeois." And commies must avoid any appearance of being bourgeois or of belonging to the bourgeoisie.
Crystal Springs Reservoir is a man-made lake. The dam that holds the water back is pretty old, and the San Andreas Fault runs right through the reservoir. Downtown San Mateo is downstream from that dam.
What could go wrong?
and food comes from a can or a box.
No need to worry about the farmers, ranchers, or commercial fishermen who work hard to produce our food.
Now it's buried under 50 feet of silt, so it's got that going for it.
I don’t see a problem. I turn the thingy here and water comes out of the faucet. -concerned liberal
Wait! Wait! You’re telling me it is possible for San Franciscans to smell worse than they already do?

Hetch Hetchy project uses freezing technique
Wednesday, October 31, 2012
“...”We’re actually about 83-percent finished with the tunneling. We got about 5,000 feet to go, which is a very exciting point. We can actually say, because of this project and the one’s we’ve been able to accomplish in the last year, that the system is seismically a lot stronger than it was even a year ago,” said Barry.
Work on the Hetch Hetchy seismic upgrade project is expected to be completed in March 2015.”
If drained, the site would actually turn into a dead canyon full of mud and silt.
Hetch Hetchy is Yosemite’s smaller twin.
John Muir said this:
“Dam Hetch Hetchy?! As well dam for water-tanks the people’s cathedrals and churches, for no holier temple has ever been consecrated by the heart of man.”
Hardly. They are constantly preaching the "Peak Oil" scenario.
Yes you are correct, that is what they preach. Oh Doom and Gloom we are using up all of the Earth’s resources!
However the actions of government that they advocate create conditions that would cause great reductions in the availability of gasoline. Rather than encourage the discovery of new sources of mineral wealth they advocate severe reductions in mining and drilling.
Yet famous Liberal advocates of restrictions on traditional fuels use are some of the most blatant profligate users of traditional fuels.
The Liberal in essence wants to have gasoline available for them to use but doesn’t want anyone else to have gasoline.
Liberals practice magical thinking. Hypocrites.
Got me there.
Not to mention the protestors and interveners that would delay the acceptance of the Environmental study report.
Sure it wouldn’t be easy.
I can imagine that the tunnel would be relined in sections. The surface of the tunnel would have to cleaned, any cracks grouted and then preheated before the liners was extruded in to place.
I used to live in San Mateo and all that you point out is certainly true. That said, the issue was a supply tunnel collapse in and of itself causing am immediate loss of water supply to SF. Now if the CSL dam were to go, all bets are off and you’d need water wings if you lived in downtown San Mateo or Burlingame.
