A lot of people outside of cities have their own groundwater wells, which is at least part of what the article is talking about. How do you price water people are pulling directly from the ground with their own equipment?
Rain barrels are/were illegal in a lot of US areas because you didn’t own the water that landed on your property.
Holy good God it’s not totally fabricated. https://www.truthorfiction.com/collecting-rainwater-is-illeg...
My parents live in an area where there is no municipal water system. Due to the geology for both water supply and septic systems, they mandate a minimum lot size of 4 acres.
With conservation, rainwater collection, gray water re-use, incinerating/composting toilets and/or engineered septic fields, a lot can be done without a lot of groundwater or usable natural septic field.
