Our main source is from a water tank. Cisterns were and have been used for many decades. Our Apartment handyman said he had a 3000 gallon cistern when he was a kid and bucket scooped water since his mom did not want plumbing by choice. Said the 3000 gallons lasted late fall till early spring. They had 8 people in the family. We will pump from the cistern the same way one does from a well. For washing clothes/bathing and dishes who really cares. Its ingestion that we need purified water. We humans did not turn ultra fragile over the last 10 years......only our minds have.

A toilet tank is not a sealed unit and is open to the air. The brown scum is undoubtedly a product of airborne bacteria. These types of bacteria can be chlorine tolerant. Hot water tanks are sealed units.

Has anyone ever came across what type of tank would be approved to handle city pressure? I don't want to order a stainless steel vessel from a local welding shop as AB welders make more money than god (not even joking).

Is this something that you would need to buy from a plumbing supply shop or is it a specialty object I guess I'm wondering. I'll rub the belly of The Google as well and post if I find anything. But if any of you are plumbers, would love to hear from you!

thanks,

Since this thread started I have been looking all over for a youtube video I saw a few weeks ago and I can't find it. It was a great big tank - 5 times or more the size of a hot water tank and it held the water in between the source and the house. The water kept flowing through it so it was constantly renewed. I don't know how else to search for it except that it was at a preppers convention in the US and someone was interviewing the man at the booth.

I don't know if that will help at all...I'll let you know if I find it back.

I have a deep well for my drinking water. As it is about 300' deep, the pump is located in the well itself. There is a pressure tank in the basement that supplies the house when the pump isn't running. When the pressure in the tank drops from opening a faucet, the pump kicks in and refills the tank to a preset pressure. Mine is only about 5 gallons, but needs to be replaced soon, as I have to add air in the bladder every few months. This summer, when we will be putting in the foundation, I will be replacing the tank, but for one that is much larger...I have seen them as big as 60 gallons installed. since this type of system works by turning a pump on and off in the well, could one not adapt it to a municipal system that would simply control a valve that would open and close as needed?
The company that made my tank sells them as big as 119 gallons.

I had the same thought for our system Denob. Our pressure tank is fairly large but 119 gallons would be a really nice back up. The water can be accessed by a faucet at the bottom of the tank if the electricity is not working (for those of you who haven't seen a pressure tank in real life) We are about ready to replace ours as well.

thanks for those ideas... maybe I was trying to create a complex solution for a relatively simple problem...

I need to find a plumber who works in the country as they will have experience with these systems.
thanks,

One place to look for a large water tank is the local scrap metal dealer, or if a large building is to be demolished, see if you can salvage one from them.
