How Long Does a Water Truck Take to Fill a Pool? Load by Load

How long does it take a water truck to fill a pool? Less time per load than most people expect, because one tanker load of 6,000 to 8,000 gallons usually unloads in well under an hour once the hose is laid. A pool that needs three loads takes longer than three times that, though, because between loads the truck drives back to its water source, refills and comes back to you. That round trip is what can turn well under an hour per load into most of a day for a 20,000-gallon pool with one truck.

Unload time per load

The driver parks on the street or driveway, runs the hose to the pool and opens the valve. From there each load usually unloads in well under an hour. On the last load, the driver stops when the water reaches the level you agreed, which is usually the middle of the skimmer opening.

Emptying 6,000 to 8,000 gallons in under an hour means the truck is putting in more than 100 gallons a minute, at least ten times what a garden hose manages. At 5 to 10 gallons a minute, a hose needs 10 to 20 hours for the same 6,000 gallons, so one tanker load saves most of a day of hose time. The hose fill times table has the hours for every pool size.

The refill trip is the hidden time

After the first load the truck leaves. It drives to the hauler's water source, usually a hydrant meter or a bulk water station, fills the tank and drives back. That round trip, repeated for every load after the first, takes up most of the clock on a multi-load fill.

Two things set it: how far the source is from your address, and how many loads the pool needs. A hauler filling a few minutes away can keep the water coming with only short gaps. One driving across a county leaves a gap between loads that can be longer than the unload itself.

A 20,000-gallon pool, hour by hour

A 20,000-gallon pool is 3 loads on an 8,000-gallon truck and 4 on a 6,000. With one truck, the day runs like this.

With a short round trip, three loads can be done in a morning. With a long one, the same three loads fill most of a working day, and a fourth can push the finish into the evening or the next morning. The tanker loads calculator tells you how many loads to expect before you build the day around them.

What slows a delivery down (hose reach, access, water source distance)

Hose reach comes first. The first 300 feet of hose from where the truck parks are included. A longer run takes more time to lay out and pick up, and it adds a hose charge, shown in your quote before you book.

Access is next. A locked gate or a blocked hose route can stop a delivery altogether. If the truck can't deliver because the site differs from what you described, it leaves, and a dry-run fee of 50% of one load applies.

Distance to the water source is the one you can't change, but you can ask us where your hauler fills up.

Same-day vs split-day deliveries

Most fills of 2 to 4 loads finish the same day. A 5-load pool with a distant water source, or a hauler with other jobs that day, can be split across two days.

For an existing finish a split does no harm. For new plaster, pebble or quartz it's the thing to avoid. Water left at one level on curing plaster can leave a visible ring, which is why builders ask for a continuous fill. Tell us it's a new finish when you request the quote, and we plan back-to-back loads or a second truck so there is no long pause. The filling a new plaster pool guide covers the builder's side of that day, and the complete fill guide walks through truck and hose procedures step by step.

How to speed things up at your end

• Measure to the water line so the load count is right the first time.
• Give the real hose distance, measured from where a truck can legally park to the edge of the pool.
• Take the lock off the gate the night before and move anything the hose would have to snake around.
• Be there for the first load to show the driver where the hose goes, and stay reachable by phone after that.
• Have the pump and filter ready to start once the water reaches mid-skimmer.
• Be flexible on the date, and tell us if it's a new finish so we can plan the loads back to back.

Frequently asked questions

How long does pool water delivery take from request to truck?

Your estimate shows on screen as soon as you send the request, and the exact quote usually follows within 1 to 2 business hours, Monday to Friday. The delivery date depends on your area and the season, so tell us if your date is flexible.

How fast does a water truck fill a pool compared with a hose?

Each 6,000 to 8,000-gallon load unloads in well under an hour, while the same water through a garden hose at 5 to 10 gallons a minute takes 10 to 27 hours. A 20,000-gallon pool is usually a one-day job by truck and about 33 to 67 hours by hose, which is one and a half to three days of nonstop running.

Do I need to be home for the whole delivery?

Usually someone should be there at the start to open the gate and confirm where the hose goes. After that, being reachable by phone is normally enough.

What if the pool is full before the last load arrives?

You don't pay for loads that haven't been dispatched when the pool is full. If the pool needs more than estimated, extra loads are billed at the quoted per-load price, and we ask you before sending one.
