The cost of providing safe drinking water is a few pennies per gallon, city or private . . . Initial cost of drilling wells, coupled with power , EPA quality testing, and other costs amortized over 20 years works out to a very minor cost.
The cost comes in the disposal of the wastewater and refuse. Wheather city or private waste treatment and disposal by far exceeds the cost of quality water production.
OP asked a valid question to which they have recieved many valid answers, however the topic does not address the larger issue of wastewater disposal.
Filling fresh water is limited in many places due to the fewer places to dispose of the wastewater.
Consider Custer State Park SD . 5 camps scattered over 20 miles each with a entry water fill tap power but 0nly 1 wastewater dumpstation , 450 sites total There is 1 dump station at the Game Lodge camp ground. This is by design and necessity as other Black Hills soils are difficult to absorption.
Its a simple question to ask about quality drinking water. A much more costly and difficult one to consider the waste treatment.
Educate yourselves about the transport and proper disposal of waste. Theres the cost and difficulty.
