What is the cost of filling an above ground pool with water?

It depends on the pool size and where you live. I have an above ground 24 ft x 52 in pool and it cost about $260 for 2 5000 gallon tanks. I still had to add some but that gives an estimate.

Depending on your area most city water systems charge between $2-3 per unit (748 gals.) A 10,000 gal. pool at $2.50 per unit would cost about $33.
