I have the opportunity to purchase two of these tanks for a very good price. I want to use them as potable water storage for a low producing water well. How to do know if the material is safe for potable water?

  1. Should be a manufacture label on there someplace . Look it up. 99% of the time they’re good for water. Add some bleach occasionally and you’re good.

    OP you will still need to have some sort of water purification down stream of this. You will want at minimum a filter, possibly a softener depending on your water hardness, and probably a UV system.

    You will need to learn how to dose bleach to shock it as well.

    Lived on cisterns for a few years, you can make it work, but you gotta keep everything clean otherwise they warm up which can make it a breeding ground for bacteria and parasites.

    Please say the “good price” so you don’t get took on some used dryrot tanks

    We have one of these. Looks like a Norwesco black vertical storage tank. This page has some documentation on its intended use (should be safe for potable water assuming that’s what it is).

    We use ours for rainwater catchment to water animals and our vegetable garden. I would be little bit hesitant to use it for domestic water unless you keep it real clean and have a pretty robust treatment system (Filter, UV, carbon, chlorine or Ozone treatment, etc.) but I’m kind-of a princess when it comes to water quality.
