The Auxiliary Water Supply System (AWSS, though often referred to on manhole covers and hydrants as HPFS for High Pressure Fire System) is a high pressure water supply network built for the city of San Francisco in response to the failure of the existing emergency water system during the 1906 earthquake. The Twin Peaks Reservoir is the backbone of the AWSS system and is located at the top of San Francisco's Twin Peaks hilltop. It is made up of a 10.5-million-U.S.-gallon (40-million-liter) storage reservoir made out of 6-inch-thick (150 mm) reinforced-concrete slabs. Two 750-US-gallon-per-minute (2,800 L/min) centrifugal pumps deliver fresh water from the city's domestic water system. For safety, the reservoir is broken up into two tanks, and each tank can be emptied separately so that only half of the reservoir is lost in case of a pipe breakage. The tank is set at 758 feet (231 m). The Ashbury tank is directly connected to the Twin Peaks reservoir and has a total capacity of 500,000 US gallons (1,900,000 L). The tank is set at 494 feet (151 m) and, when combined with the Jones Street tank, can provide hydrants with 214 pounds per square inch (1,480 kPa) of pressure. It is located at 1234 Clayton Street, in the city's Ashbury Heights neighborhood. The Jones Street tank is directly connected to the Ashbury tank and has a total capacity of 750,000 US gallons (2,800,000 L). The tank is set at 369 feet (112 m), providing hydrants with 160 pounds per square inch (1,100 kPa) of pressure. It is located at 1239 Jones Street in the city's Nob Hill neighborhood. There are two emergency pumping stations present within the AWSS: Pumping Station No. 1: Basement of San Francisco Fire Department Headquarters, 698 Second Street at Townsend St. Pumping Station No. 2: Van Ness Avenue and San Francisco Bicycle Route 2 in Fort Mason. Both stations are capable of pumping 10,000 US gallons per minute (38,000 L/min) of salt water at a pressure of 300 pounds per square inch (2,100 kPa) with on-site generators. Pumping Station No. 2 is listed on the National Register of Historic Places. To supplement any failure of the pumping stations or reservoirs, the city’s two fireboats can be utilized to deliver salt water into the system. They can also deliver water by hose line to areas near the waterfront. _Phoenix:_ 9,600 US gallons per minute (36,000 L/min) at 150 pounds per square inch (1,000 kPa) _St. Francis:_ 18,000 US gallons per minute (68,000 L/min) at 150 pounds per square inch (1,000 kPa) As a final measure to counter a failure of the AWSS piping, the city maintains a network of 177 independent underground water cisterns.[8] Sizes vary from 75,000 to 200,000 US gallons (280,000 to 760,000 L) with a total storage capacity of over 11 million U.S. gallons (42 million liters) of water. These cisterns are easily spotted at street level with manholes labeled _CISTERN S.F.F.D_ surrounded by red brick circles or rectangles.

San Francisco is more prepared because of the Loma Prieta 1989 earthquake that led to fires because the pipes at that time couldn’t handle the high water pressure. San Francisco has kept its fire system updated but it seems that didn’t happen in LA and as a result old pipes that cannot handle the high water pressure, were not replaced on time. The fires in Los Angeles also Hawaii is a reflection of the current deterioration of American public infrastructure. In fact, one economist reported that most American public infrastructure has not undergone a major overhaul since the 1980s and in some areas it’s no different than upcoming middle class economies like Thailand. This should come as a concern to the entire nation that the aging infrastructure cannot handle disasters in a mass scale, and many cities are unprepared to cope with climate change.
Not only this issue...Golden Gate Park...look at the mess of dead trees and dry under brush and weed patches, one spark and "poof"...and a LA situation!
~ Ive been telling people for years ~ that the Brick Circles are where the Cable Cars used to Turn around = I guess I learned something today ... So ill share one wit U All, I keep a $2 Earthquake Whistle on a hook next to my bed, in the Event of a killer Quake and Building Collapse ~ your ability to blow a Whistle will outlast your ability to scream for help ~
In San Diego, while there isn't a citywide auxiliary water supply system akin to San Francisco's AWSS, specific measures have been implemented to bolster firefighting resources: High-Rise Building Requirements: The San Diego Fire-Rescue Department mandates that high-rise buildings maintain a secondary water supply. This ensures that if the primary city water main supply is disrupted, there is an alternative source available for firefighting operations. Rapid Aerial Water Supply Tanks: To enhance wildfire response, San Diego County has introduced Rapid Aerial Water Supply tanks, such as the "Heli-Hydrant." These tanks provide a reliable source of clean water for firefighting helicopters, enabling quick refills during aerial firefighting efforts. This innovation was instrumental in containing the Fallbrook wildfire, preventing significant damage and expediting helicopter response times.
GOD: “For my people have done two evil things: They have abandoned me- the fountain of living water. And they have dug for themselves cracked cisterns that can hold no water at all! (Jeremiah 2:13 NLT)
Pretty cool. Hopefully “the big one” wont crack them n make water spill out. Im probably not understanding the source of it but if its sea water i guess thats reassuring
The Fire Department maintains and expands the Auxiliary Water Supply System. The Water Department does not maintain it.. You can see the fireboat at 3:31 operated by the SFFD. The large, white oversized hydrants that are supplied by the AWSS/HPFS, of which there are 1,889, are visible throughout the city. Firefighters use these High Pressure Fire System hydrants every day.

Thank you.
Great info and this is a prime example of fire prevention. 😊
That's so awesome! Definitely prepared if anything happens!
Great reporting with clarity.
THAT is what you call LEADERSHIP
Wow. Competence in SF management. I'm kind of stunned.
😂
All in place well before Newsom 😂
The 1906 San Francisco earthquake was a huge learning experience for the city.
@@Einsteinbomb That and the city also learned from 89. I've been in condo's in a "liquefaction zone" with concrete so thick you can't get cell service. Still not worth the risk I moved 😂
Built when conservatives ran the city
This is a Chief that knows where the water comes from, good on her.
San Francisco was on the verge of getting rid of the fire boats in 1989. The Loma prieta taught us better.
We learned from this in 1906. Never again. Mission district & Dolores Heights area survives because we had a lagoon running underground in the area.
Growing up in the city, I learned about those because of the 1906 earthquake
Working in SF for over 25 years, SF has no problem with water and putting fires out.
Yet?
Would you like to trade mayors with Los Angeles?
@@KK-pm7ud no no, we just got a new one. it's your turn.
@aggu5477 We can throw in a couple of tickets to the Olympics and a tour of Universal Studios. What say you now?
The city hasn't had a HUGE disater. we aren't talking a grease fire.
Phew😂 yes. What a relief. Thanks for the report.
Check the hydrants every year to make sure they are functioning as expected

I’m moving to San Francisco one day thank god it’s okay!
I'm wondering about San Jose, CA Fire Highdrants?????
They should do a hydrant check in all major cities
That’s great, finally SF is ahead somewhere. Let’s get Richmond and Sunset cisterns going.
I doubt it! Just like 1989 earthquake they couldn't put out fires in the Mariana.
2034
@@BobChippewa Why would they have anything to do w/ the "Mariana" Trench? Oh, did you mean Marina* ?
So communication about those facts should be made to all those - who critisize - so fast ❤
well after an earthquake and fire in 1906 as well as 1989, i hoped that we would have built a back up plan.
U BETTER CHECK
They’re lucky they’re surrounded by seawater as a peninsula.
Not only this issue...Golden Gate Park...look at the mess of dead trees and dry under brush and weed patches, one spark and "poof"...and a LA situation!

Antonio Rivera, looking good brother. Great system. LA county should have followed SF
That lady just discovered gravity.
Yea but did they open one up to show the water In it?
Anyone know about San Diego's ???

I wish LA had this! 😢
Los Angeles is over ten times larger than San Francisco in total area.
war and disaster time....morality donation meditation
Another peppermint Patty 😁
How safe are these during earthquake? Would they crack and all water leak?
They've lasted through the Loma Prieta earthquake in 1989.
Can’t say never.
~ President ( Lying - Felon ) should know about this ....
Plug it up to the ocean 🌊 😂
Can't it handle 1000 homes burning at the same time? Maybe not....strong wind plus fire plus not enough firefighters = not good
no
This is what its neighboring cities should be allocating their budget at, not on useless and woke programs.
That water is not for you I can assure you of that
I love you SF!!!
Lol

And there’s 10,000 gallons of spring drinking water dumped in the bay every day
All BS..

You're a douche so maybe you can actually be useful.
The City has a robust DEI policy. Just saying.
Thankfully these were implemented before DEI was a thing. Let’s hope DEI doesn’t interfere.
@@Simply418 You fail to understand their capacity to f it all up. You are so innocent.
Pretty cool. Hopefully “the big one” wont crack them n make water spill out. Im probably not understanding the source of it but if its sea water i guess thats reassuring
The question is do we have capable fire people who know how to use the system? I don’t want to mention the three letters.
I think you mean 4 letters: MAGA

Of course we do.
Irrelevant question.
Every employee is trained. Duh.....
This ISN'T Alabama!
Of course they do!
As long as it doesn't have feces 😅😂
The cisterns are sealed.
SF is the next toaster.
The big problem is is all the silicone plastic and Botox that are injected in people's lips and faces is highly flammable😅
They currently need 236 DEI firefighters to fill the quota as we currently speak.
Kenya Karen destroyed LA, hair gel Gavin CA and creepy Joey USA
san francisco = comun sense.
The city is too far gone.
Don’t tell Newson , he’ll have it destroyed
The system was already in place when Newsom was SF Supervisor and SF mayor.
SF is a dumpster fire already.
That and much crime.
Let me guess the big cities are scared so now we need a news coverage for water supply systems 🤣
No.....we need NEW emergency water systems ! In every American city ! Duh.....
@AmericanTeacher-USA wake up, you know the u.s is cheap right and also likes to keep things historic 😂
so fire hydrants are only to cause parking difficulties?
First !
