Times approximate. Got preps?
thats a part of,one of my what if scenario's..like,what if there was a power grid failure?all those things you pointed out will happen in a power grid failure..
no im not ready for it to happen..
Was doing ok until the water supply being exhausted...otherwise, not too far off.
Yep, bottled water may run out, but city water could run for a long time without trucks.
In fact, the microbes they use, are pumped between tanks and buildings, to keep it growing (much like Baker's yeast or a batch of sourdough).
Did you just say they grow water with microbes?
No, they use microbes as part of the cleaning process. Beyond the settling tanks, and filtration, there is quite a bit more done to process water, to return it to use as drinking water.
These small muni systems on ground water out here, it goes to the settling tank, gets chlorinated, and straight to the space ball for distribution.
I thought you were saying they were actually growing water with microbes.
In a power grid failure, the municipal water supplies will run out much faster than 4 weeks. They only can pump the water for as long as their fuel reserves allow. A couple of years ago, I installed quick disconnect cabinets for a city at each of their three pumping stations. If power went out, their plan was to roll up with a temp generator and plug it into the cabinet to bring the station on line. At the time, they said that they could run in this configuration for a long time, but refueling was the difficulty. There was no on site fuel storage, it was all to be trucked in via a fuel company daily. That was one of their big weakness's in their plan.... what happens when every body is calling for refueling....something is not going to go right guaranteed....Murphy's Law.
Why yesss, it's my evil plan to take over the world! I'll make so much water, I'll drowned all those pesky ISIS-holes, and liquidate Texas, hahahahshshshsha....
On site fuel reserves, here.
Each and every town and city will have different preparedness levels with things such as fuel reserves. Has anyone ever looked into how their local jurisdiction fares in this department?! This may be a good indicator of how your area will endure and survive an extended emergency.
LOL You'd make Trump look like a pauper if you could fabricate water. Time to put that evil genius to work.
You CAN fabricate water, it is just not cost effective. ( hydrogen and oxygen... Some assembly required)
There is a filtration process used in some treatment plants called "biosand." It works for reasonably continuous treatment needs. It employs a tank with sand several feet deep and water is supplied at the top surface of the sand and drawn off at the bottom with a drain network. Within the sand a layer will develop with a bacteria that sticks to it and happens to eat (hence kills) other bacteria and viruses as water slowly permeates through this layer to the drains below. So the sand traps sediment and harbors a bacteria which actually purifies the water. Generally settling ponds are employed upstream to reduce the amount of sediment the sand filters are exposed to increasing duration between sand changes. A key to the biosand filters is the water level and continuous flow. It is critical the biolayer of sand not dry killing the good bacteria nor interrupting flow too long starving the bacteria. It also takes like 30-60 days for the bacteria to adequately develop and temperatures are important factors in all this too. Some pollutants can also kil the bacteria compromising the biosand filter's effectiveness. I don't how much it is still used anymore for municipal systems with other technologies available.
Still in wide usage. In the most up to date forms, the sand bed is made of graduated layers, coarse on top, finer the further down you go, and an activated charcoal layer at the bottom where the beneficial bugs are encouraged. The sand layers are backwashed periodically to remove the sediments, and then settled out assuming their layers due to the difference in gradation. Works well, but with a power outage a lot of function gets lost if the outage is prolonged.
Periodic change and regeneration of the charcoal is pretty well automated as well. Turns out that all that automation is actually economical compared to previous means and methods of cleaning the beds and reseeding the bugs.
Newer methods include reverse osmosis and membrane filter systems. These are not too well adapted to "small" muni systems, but work well in multi million gpd plants. So far, they are pricy to build and operate, but the technology is rapidly advancing. One of the problems is that a hamburger flipper can't operate them, it takes some significant training at a technical level.
and that assembly process is Quite ENERGETIC........
Or just wait for rain....
That process does not create water, it just changes it's form. But yes, it is much more cost effective.
Odd, I thought the planet was something like 80% water.
People go into such a tizzy over water. (ok I understand living in a desert...)
If it's not potable as is, purification (by whatever method), even distillation of ocean water is easy enough.
Then again sheeple will panic and scream once the stoopidmarkets run out of bottled water.
What a scam. "Bottled water" !
I remember one of the Massachusetts TV stations we get up here running a PSA advising the sheeple to "Boil your tap water to purify it and remember to let it cool before drinking it."
Yeah, some of them mass holes really are that dumb.
They do issue boil orders, anytime there has been a water main break with a loss of pressure. (A chance for something to backwash into the water system)
Now, telling them to wait until it cools, is CYA, or some idiot will claim injuries because he was not TOLD not to drink HOT water.
