Shared well sporadic pressure


We have had this property about 20 years bought the land from owners that sold 1 acre lots and about 6 of us opted to be on their well, and pay a small fee. We are in florida and the water is very good water. so it has been great and never runs out. However from time to time the pressure goes too low for our liking. The question is can I add a pump and pressure tank on my end to boost the pressure? Thanks

Yes, but I think while the pump is running, it would reduce the pressure to your neighbor's supply even further. Then they might get ticked!

What might be better would be a "buffer" or gravity tank, then the pump, then your pressure tank.

The 1st tank could take its time filling up from the currently available pressure. And then your pump would draw from that tank to fill your pressure tank. There would be no reduction of pressure to your neighbors when your pump kicked on if this was designed properly.

You should also install a "check valve", so once water goes into your first tank, it stays there. (Would not flow back to your neighbors when the perssure was excessively low.)

That makes sense what would the min size tank be do you think as we dont have high demand. Thanks Eric

The best idea would be to have all 6 of the places set up like this so that the pressure on properties 1-5 aren't affected while property 6 is drawing from the system to fill their tank.

That you would need to figure out on your own. Quite a math problem. Determine pressure, size of pipe, and amount of time you have water running.

Another way to solve the problem is to go look at tanks and their prices. They are not cheap! Consider freezing and what you night need to do for that as well. Maybe underground. Maybe above ground, build a building, then heat it.

And the first tank would need to be vented or have a "bladder". If it was just a sealed tank, then the pump would suck out as much water from the supply pipe as it was pumping out. Same as connecting it to the water pipe.

Anyway price may dictate what size tanks you get...

If the well is being overdrawn and you add another pump going to your house then the neighbors willl experience even more of a pressure drop.

One thing you could do that will probably not affect the neighbors is to put a storage tank in your attic for gravity feed (This tank would also have some air pressure in it so the water will come out during times of low pressure from the well.) The existing pump in the well would refill this attic tank at its leisure. THis tank would probably need to be 40 to 60 gallons since the pressurized air pocket will occupy about a third of the space in the tank after the well pump gets up to the system pressure.
