Hetch-Hetchy project needed to fix weaknesses

Original post made on Sep 25, 2007

Water for Palo Altans, and 2.3 million other Bay Area residents, flows down from the Sierra through a series of pipes and tunnels, crossing five seismic faults.

As a participant in the PaloAltoGreen utilities program, I'm concerned that some of the water being supplied to me by Palo Alto utilities would further threaten the beautiful Tuolumne River. I'd like to see Palo Alto team up with other Bay Area cities to pressure the SFPUC to take conservation issues more seriously and find other ways to address the seismic saftely and growth issues.

Conserver, now is the time to start using recycled water. San Jose is planning to build the largest plant in California to recycle water and mix it with fresh water. Recycled water is actually cleaner than Hetch Hetchy, but it's a problem selling it to the users.

Conservation is one way to deal with a water shortage but so long as every American continues to take a shower every morning we have to start using recycled water. Europe is way ahead of America in using recycled water.

There is no water shortage in California, there is a storage facility shortage.

Astronauts on the space station use recycled water for everything, they cook with it, drink it.

All water is recycled - however I agree that it is foolish to send recyclable water into the ocean if the energy cost of reclaiming it is less than the energy cost of desalinization.

Walter, the costs of recycling water are much less than desalination because the water is right there in the sewage treatment plant. The process to make water drinkable from waste water is far cheaper than removing the many elements in sea water.

The technology to recycle water has been around for some 30 years; the problem is convincing the general population that recycled water is as drinkable as so called fresh water. At the moment recycled water is used mainly on landscaping.

Since sources of fresh water are becoming more scarces worldwide, the world will have to think in terms of recycled water, particularly if those locations are hundreds of miles from the sea.

Recycled, you are 100% correct. Are you sure you are a Palo Altan?

Right. I have actually seen dignitaries drink a shot of recycled sewage water, right there on TV. I always wondered if they took a fresh water chaser off camera. I would.

Sure, astronauts drink the stuff. They're paid to. It's because the earthlings down here are too cheapskate to send up fresh water.

PA's treatment plant takes a lot out of the sewage, including the smell which it dumps overboard for the delectation of all. But it leaves in the salts and minerals and (joy) lots of pharma and its metabolized byproducts. The latter are the latest handwringer for the ecology set.

But you guys go ahead and drink your recycled cocktails, over and over as many times as you want to. I'll just drink the nice clean Hetch Hetchy H2O you save.

Why limit water cycling to sewage water (which is a good idea)? Why not recycle runoff water during winter storms? Store the runoff in upstream reservoirs, and downstream reservoirs, then reccycle through the existing (in the future) recycling technology already in place for the sewer water. Pump recycled (thus purified) water into underground aquifers, if needed, for storage (to prevent evaporative losses).

I will gaurantee that the poster identified as " Recycled Water, a resident of the South of Midtown neighborhood" is somehow connected to the water recycling industry. These guys lurk around blog sites and try an pump up enthusiasm for drinking tertiary treated sewage effluent. The poster identified as "Tom, a resident of the Professorville neighborhood" is exactly right. There is a lot of money to be made in promoting recycled sewage effluent and these guys are all for making that money.

Tom. you go ahead and drink your unfiltered Hetch Hetchy water. Just answer this - what do the bears do in the woods? As for me, I have to go deposit my bribe check,
