Quick volume chart for in-ground, above-ground, and gunite pools — plus how many tankers and what NJ delivery typically costs.
Whether you're filling a brand-new gunite pool or refilling after winter, the first question is always: how much water do I actually need? Here's the quick answer for the most common residential pools in New Jersey.
To estimate gallons for a rectangular pool: length × width × average depth × 7.5. Average depth is usually 5 ft for a flat-bottom pool and 6–7 ft for a pool with a deep end.
| Pool Size (ft) | Avg Depth | Approx. Gallons | 4,000-gal Tankers |
|---|---|---|---|
| 12 × 24 (288 sq ft) | 5 ft | 10,800 | 3 |
| 14 × 28 (392) | 5 ft | 14,700 | 4 |
| 16 × 32 (512) | 5 ft | 19,200 | 5 |
| 18 × 36 (648) | 5.5 ft | 26,730 | 7 |
| 20 × 40 (800) | 6 ft | 36,000 | 9 |
Round above-ground pools use: π × radius² × depth × 7.5.
Note: We do not fill Intex pools, kiddie pools, or DIY inflatables. For permanent above-ground pools (steel/resin wall, 15 ft+ diameter), we can deliver.
No — volume is purely a function of shape and depth. But the fill rate matters: vinyl liners must be filled steadily so the liner sets evenly, and new gunite plaster needs continuous fill to prevent a ring. A bulk tanker delivers 4,000 gallons in roughly 30–45 minutes per truck, which is fast enough for both.
An average residential garden hose delivers around 9–17 gallons per minute. For a 20,000-gallon pool, that's 20–35 hours of nonstop hose time, plus your municipal water surcharge for "sewer-billed" water that never enters the sewer. Many NJ townships also charge above-tier rates for high-usage events.
A bulk delivery skips the wait and the surcharge: one or two tankers, half a day, done.

One 4,000-gallon tanker offloads in 30–45 minutes. A 20,000-gallon pool with 5 loads takes about half a day, including driver turnaround time.
Yes. Our tankers are 3A Food-Grade stainless steel and the water is sourced from chlorinated municipal supplies. For swimming pools the water is delivered as non-potable bulk fill — your pool's chemistry will still need balancing after the fill.
We do not fill Intex pools, DIY inflatables, or kiddie pools.
