Estimate what it costs to fill your pool, and how long a garden hose will take, from your volume and local water price.
Water is usually billed per 1,000 gallons or per CCF (hundred cubic feet, which is about 748 gallons). Divide your pool volume by the billing unit and multiply by the price. Some utilities also charge sewer fees on water you use — add that rate if it applies to you. A typical garden hose flows 8–12 gallons a minute, so large pools can take a day or more to fill.
