Calculate the expected impact on your water bill. Avoid

Quick Conclusion
Filling a 20,000-gallon pool typically costs $80 to $200 in most US cities. However, if you don't call for a sewer credit, the price can double. Check your bill for the "Cost per 1,000 Gallons" (or CCF) to get an exact estimate.

Technical Comparison

Billing Unit Gallon Equivalent Typical Range
1,000 Gallons 1,000 Gal $3.00 - $9.00
1 CCF (HCF) 748 Gal $4.00 - $12.00
1,000 Liters 264 Gal $1.50 - $4.00

Pro-Tip

The "Freshness" Value: While $150 might seem expensive for water, starting with a fresh pool means you'll spend 50% less on chemicals in the first year than you would fighting old, mineral-heavy water. Treat the fill cost as an investment in a balanced chemistry foundation.
