Wells, Sump Pumps and Septic Sewage Systems - Booster Pumps and community water well

I share a water well with 6 other cabins. I am about 400 feet from the well, and am the farthest away. I have not seen the well room but am told it consists of the pump, a 30 gallon pressure tank and a main manifold header with 7 -1 inch valved polybutel lines. When the neighbors are down, so is the pressure. when all cabins are full, at peak times, there is basicly no water. I was going to install a booster pump and pressure tank, with a check valve at the valve to prevent backfeeding the system. My question is if all the cabins are full and I am using enough water to have my booster pump run, won't I suck air out of their faucets that are on?? Is there a better way to do this??

You have a good idea, but (with every good idea there's always a but) the main tank you are feeding off of will go dry as you pull more water out with the booster at peek times.

The set up you want, is what I am using now. During peek demand times, my little pump will pull more water than was available, and will start to suck air from the main tank(120gal). If too much air starts to go through the pump, it will tear up the pump.

The main tank that I feed off of has since been enlarged.
Even though the pressure will still drop in the main tank, the booster I use will still give me the pressure I need. With the larger main tank(1000gal)there is now more volume to pull from.

On a side note: At peek times your pump may come on when the pressure is low, and it will take all the pressure from anyone else on the system, and yes they do get up-set!!!!

Can you somehow install a storage tank on your property that will fill, little by little? Maybe up 10 feet for a gravity flow? Or underground with a pump to your cabin?
