We don't need to worry about water shortages /s

SAN FRANCISCO (KPIX 5) – The people who want us to use less water are part of a system that could be among the biggest water wasters in San Francisco. That system is in hot water, because of hot water. “After the water is heated up, the condensated water is then discharged into the sewer system,” said Tyrone Jue of the San Francisco Public UtilitiesCommission. “This is drinking water that is being used for the steam loop.”

tear down Hetch Hetchy
no .....its not close enough to S.F. to do any good....
what a flood I can Imagine...
It’s not like they just installed this system. I think this is more of a gotcha report than anything else.
Yes, they should probably filter the dirty water under the Bart station and use it. They should head toward that reality starting now.
I’m not worked up over this.
What bothers me is we have trillions of gallons off-shore, and we don’t tap into it.
Israel will get about 80-90% of their fresh drinking water from the Mediterranean in about five years. It’s already around 50% now.
California use to cutting edge.
Now it’s just cutting the breeze.
Governor Brown, you’re stinkin’ up the place.
The Totalitarian Mindset does not worry about hypocrisy in its behavior.
I was told that the voters were allowed to vote on a desalinization plant...somewhere in the state..
it was given the thumbs up,...and either the state or the feds then.......gave it a thumbs down.
Unca Jerry Knows Best!
These steam heat plants are efficient and produce economical heat.
They are common in large cities all over the country.
These are what are called open end systems as opposed to closed loop systems where the water would be returned to the plant.
Returning the hot water to the plant would drastically increase the start-up and maintenance cost of the system because it would require a large tank, chiller (to make the return water safe to pump) and at least two pumps at each building served by the system. Then piping to the return the water to the heat plant.
The spending all of that extra money for all of that extra equipment would be seen as foolish at the time. You would never get the contract.
Only GOVERNMENT can waste this much without consequences
Good old Jerry was elected to be the leader for the state. Yes, I know, heaven forbid, but this state was headed for trouble. It’s grown by a third since 2000. You can guess who most of those folks were too.
The leadership was happy as a hog in —— over it.
Now we are running out of water, and now they’re in panic mode over it.
Now you’ve got the middle class being blamed for one more thing.
Hey, cut your water use, pay more, shut up, consider yourself lucky we don’t condemn your house and put you on the street.
I hear ya. This is just one more thing for folks to talk about so they don’t have to focus on the Obama and Clinton corruption.
the ugly runs deep ...and wide in California
It sure does.
And that is inexcusable for a place that is as incredible as any place on earth.
There is a lot more than reported here?
Raw tap water cannot be used in a steam system for very long.
Wet tube or fire tube type boilers, the heating surfaces become covered with minerals, then burn through.
The water treatment chemicals are very expensive and not something the fish prefer to swim in.
Try dumping a few hundred gallons of condensate, the EPA will be right over.
This may be SanFrancisco, but I doubt they heat the water with rainbows? Most likely a large bank of gas fired boilers.
Total loss steam systems died with the energy crisis of 1970’s. Money ahead to run condensate return lines, and insulate them. The boilers much prefer hot feed water and HATE cold water.
This building does not appear to have Green Building Certification. LEED minus?
“After the water is heated up the condensated water ...”
This idiot better learn something about Physics before opening his mouth.
it appears anyone can write for a san francisco newspaper.....
My wife and I live in a Tri-level house. It was built in 1964, and it is heated with a three zone hydronic closed loop system with fin tube baseboard radiators and a radiant slab on the ground floor. I have replaced the Bell & Gosset (Red Devil) circulating pumps several times which is to be expected. If the power is switched off to the pumps, the heated water will continue to circulates as a thermo siphon.
My system modulates the loop temperature as a function of the outdoor temperature which means the pumps maintain a constant flow with variable temperature water to maintain the house at a cozy temperature during our notorious Wisconsin winters. The radiant slab serves as a thermal mass and levels out any rapid changes in indoor temperature.
One of the annoying things about a steam system is they tend to be noisy when turning on off as the radiators expand/contract. A steam system does not modulate heat output from the radiators as the steam is always at a constant temperature.
If I was building another house, I would go hydronic floors with every room a separately controlled zone. I would also put in high velocity duct-work for AC throughout the house.
We started out with an oil fired furnace which was about five feet tall and occupied a lot of room in the basement. We replaced it with a gas fired unit about the size of a two drawer file cabinet when the oil prices went nuts a few years back. It's much cleaner burning and more efficient too, and we don't have to worry if the delivery truck will make it before we run dry!
