Icemann gives some good advice. I live in dry old SoCal and have it much better than you. My well produced (according to the well company) 40 gpm. However some around here have wells that only produce 4 gpm. We have to have 10K gal. water tanks w/ fire hydrants, so the fire dept. can use the water in case of fire. Those who have wells that are low production refill their tanks over the long term. There is only me & my wife, and we use around 70 to 90 gal./day unless we do something special that requires more. So with your clan, I can imagine your demand is lots more. In my opinion, you need at least a 1K gal. and probably better off with a 5K gal. tank. Our system pumps out 600 gal. and the pump kicks on to refill the tank. One thing to consider is the stress you're putting on your pump by making it turn on and off so many times. They are made to last but yours might not last nearly as long as it could. It's much better for it to pump several hundred gallons at a time to refill the tank reservoir than turning on and off for every 90 or so gallons. I know it would be a multi thousand dollar event to replace mine. I know the pump cost two to three thousand dollars when the system was put in.
