A 27-foot round pool holds approximately 17,200 gallons of water.
A 27-foot round pool with an average depth of 4.5 feet contains roughly 17,200 gallons of water. This calculation assumes a standard above-ground pool depth. The exact volume depends on the pool's depth profile and whether it's an above-ground or in-ground installation.
Calculating Pool Volume
- Formula: π × radius² × average depth × 7.48 (gallons per cubic foot)
- For 27-foot diameter: radius = 13.5 feet
- Volume = 3.14 × 13.5² × 4.5 × 7.48 = 17,200 gallons
Water Volume by Depth
| Average Depth | Water Volume (gallons) |
|---|---|
| 3.5 feet | 13,300 |
| 4.0 feet | 15,200 |
| 4.5 feet | 17,200 |
| 5.0 feet | 19,100 |
Cost to Fill a 27-Foot Pool
- Water cost: $0.003-$0.005 per gallon
- Total fill cost: $50-$90 depending on local rates
- Delivery services: $150-$300 for bulk water
Maintenance Considerations
A 17,200-gallon pool requires:
- 1-2 pounds of chlorine per week
- 1-2 gallons of muriatic acid monthly
- Pool pump running 8-12 hours daily
- Filter cleaning every 4-6 weeks
