the long term solution is everyone has a new much deeper well drilled

municipal government gets involved in runnig water lines, including fire hydrants to the area

This adds protection during wildfires, where often people water down their own homes to keep them from burning.

another halfway solution is for everyone to add much larger water storage tanks.. say a 10,000 gallon tank could be fed normally by a well, even a poor well would provide some water.

the tank would get filled when necessary.

lets not forget the value of the drivers time to fill tanks and the truck rental cost, or the cost of fuel and repairs. that will all add up surpringisly fast, and a truck hauling water wouldnt get good gas mileage, since water weighs 8 pounds per gallon. 1000 gallons is 8000 punds plus the weight of the tank and pump....
