OK, out of my league here. (I know it's hard to believe)

How would you design a water system for 5 homes, on 4 acres each, there could be a horse or two at 2/3 of the homes, and other animals, fruit trees, probably a small lawn, 3-4 bedroom homes.

Each home would be metered and charged on the amount of water.

One well, it doesn't have the capacity to do all homes with a CSV and 20 gallon storage tank.

I've seen areas that seem to add a new tank for each new home, are they check valve isolated? Do they have a separate pressure switch that is "or'd" together with the other 4 tanks/switches. You could certainly use a CSV before the separate checkvalves to reduce cycling, I know you all just shouted YES...

Or how is it done?
