About this calculator
Filling a pool with municipal tap water costs your water utility's per-thousand-gallon rate times your pool's total gallons; filling by delivery truck instead uses a flat per-load or per-gallon delivery rate that's usually higher but much faster. This calculator computes both options so you can compare.
Worked example
Using the values the calculator loads with:
Inputs
- Pool volume: 19000 gal
- Water rate: 6 $/1,000 gal
- Delivery truck rate: 0.04 $/gal
Results
- Cost via home tap: $114.00
- Cost via delivery truck: $760.00
What each field means
Inputs
- Pool volume (gal)
- The pool volume used in the calculation, measured in gal. Starts at 19000 gal so you have a working example on load.
- Water rate ($/1,000 gal)
- The water rate used in the calculation, measured in $/1,000 gal. Starts at 6 $/1,000 gal so you have a working example on load. Accepted range: 1–20 $/1,000 gal.
- Delivery truck rate ($/gal)
- The delivery truck rate used in the calculation, measured in $/gal. Starts at 0.04 $/gal so you have a working example on load. Accepted range: 0.01–0.15 $/gal.

FAQ
How much does it cost to fill my pool?
Filling a 19,000-gallon pool via home tap at $6 per 1,000 gallons costs about $114, while filling the same pool via delivery truck at 4 cents/gallon costs about $760 — much faster but considerably more expensive.
Why is truck delivery so much more expensive per gallon?
You're paying for speed and convenience — trucks fill a pool in hours instead of days and avoid tying up your home's water pressure and sewer/septic system capacity during a slow fill.
Does sewer billing affect tap-fill cost?
In some municipalities, water usage also triggers a sewer charge based on metered water even though none of the pool water goes down the drain — check if your utility offers a 'sewer credit' or separate irrigation meter to avoid double-charging for pool fills.
How long does it take to fill a pool from a hose?
A standard garden hose delivers roughly 9-10 gallons per minute, so a 19,000-gallon pool takes about 32-35 hours of continuous running to fill from a single hose.
Accuracy and limitations
- Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
- Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
- This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
