Your pool, full by this afternoon
A typical 20,000-gallon residential pool takes about 6 truckloads and is swim-ready the same day — instead of 2 to 4 days running a garden hose. HLM Water Trucking delivers pool water in loads of 350 to 3,700 gallons across Sonoma, Napa, and northern Marin Counties from our Healdsburg yard, with metered volume so you know exactly what went in.
The load math
How many loads is your pool?
Pool volume ÷ truck capacity = loads. Tight-access properties get smaller trucks and more trips — same result.
| Pool size | Volume | Loads (3,700 gal) | Fill time | Garden hose time* |
|---|---|---|---|---|
| Spa / plunge | 2,000–5,000 gal | 1–2 | Under 1 hr | 4–10 hrs |
| Small pool (12×24) | ~10,000 gal | 3 | 2–3 hrs | ~1 day |
| Mid pool (14×28) | ~15,000 gal | 5 | 3–4 hrs | 1–2 days |
| Standard (16×32) | ~20,000 gal | 6 | Half a day | 2–3 days |
| Large (18×36+) | 25,000–35,000 gal | 7–10 | Same day | 3–4 days |
*Hose estimate at a typical 8–10 gallons per minute of continuous flow. Don’t know your volume? Length × width × average depth × 7.5 = gallons — or use the water calculator.
Filling a 20,000-gallon pool
Truck vs. hose, and water type
Garden hose: 33–42 hrs
Of continuous flow — realistically 2–4 days. On a well, that’s a serious draw-down risk. On metered city water, check your tier pricing first.
Non-potable fill
The economical choice for most pool fills — pool water gets sanitized and balanced after the fill anyway.
Potable
Ask dispatch about current potable-carrier status if your builder or warranty requires drinking-quality water.

How a fill works
1 — Call with your pool size
Dimensions or gallons, your address, and anything about access — driveway length, grade, gates, overhead lines. You get a load count and a firm price on that call.
2 — We schedule the loads
Peak season books up, so call ahead of your pool crew. Multi-load fills run back-to-back the same day.
3 — The truck arrives & fills
Hoses run from the truck to your pool — we’re careful with landscaping and finish surfaces. Volume is metered.
4 — Swim-ready same day
Start circulation and have your pool pro balance sanitizer, pH, and alkalinity the same afternoon.
Straight answers
Before you call
How much does it cost to fill a pool with a water truck?
Cost depends on three things: total gallons, water type, and distance from our water source to your property. Call (707) 485-4000 with your pool size and address for a firm number in one call.
How many truckloads to fill a 20,000-gallon pool?
About six loads with our 3,700-gallon trucks, delivered back-to-back the same day. Smaller pools take fewer; a 10,000-gallon pool is about three loads.
Can you fill my pool if I'm on a well?
That's exactly when to use a truck. Filling a pool from a residential well risks drawing the well down or burning out the pump. Trucked water takes your well out of the equation entirely.
Do I add chemicals after a truck fill?
Yes — delivered water needs balancing just like hose water. Plan for your pool professional to adjust sanitizer, pH, and alkalinity the day of the fill.
What if my driveway is steep, narrow, or gated?
We run trucks from 350 up to 3,700 gallons specifically for this. Tight access means a smaller truck and more trips, not a canceled job. Describe the driveway when you call and dispatch matches the truck.
Are there water restrictions on filling pools in Sonoma or Napa County?
Restrictions vary by district and by year. Trucked water from a commercial source is often treated differently than filling from your municipal connection — call us and we'll tell you the current rules for your area before you schedule.
