Truck Delivery vs. Garden Hose: The Best Way to Fill a Pool

Published October 20, 2026 · Pool Water Delivery

There are two common ways to fill a swimming pool: run a garden hose from your own tap, or have a water truck deliver it. A hose is usually cheaper per gallon if you are on city water. A truck is much faster and is often the only practical choice on a well. Here is how to work out which makes sense for your pool, using your own numbers instead of guesses.

Step 1: Know how many gallons you need

Everything starts with volume. For a rectangular pool, multiply length × width × average depth × 7.48 to get gallons. A round pool is diameter × diameter × depth × 5.9. Or skip the math and use our pool water cost calculator, which handles rectangular, oval and round pools and shows a ballpark delivery cost. A partial top-off after winter or a repair needs far less water than a fill from empty, so measure how many inches you actually need to add.

How long a hose fill takes (measure it yourself)

Hose flow varies a lot with water pressure, hose length and diameter, so the best number is the one you measure. Time how long your hose takes to fill a 5-gallon bucket, then divide 5 by the seconds and multiply by 60. That is your gallons per minute.

Divide your pool's gallons by that flow rate to get minutes, then by 60 for hours. For example, if your hose fills the bucket in 30 seconds, that is 10 gallons per minute. A 20,000-gallon pool would take about 2,000 minutes, or roughly 33 hours of nonstop running. Running a second hose from another spigot helps only if your water pressure holds up with both open.

A long hose fill is fine for many homeowners. It just means planning around a day or more of running water, checking on it, and not letting it overflow overnight.

What a hose fill really costs

Water from your own tap is not free. To estimate the cost, look at your water bill for the price per unit. Many utilities bill per 1,000 gallons, and others bill per CCF (100 cubic feet), which is about 748 gallons. Multiply your pool's gallons by that rate.

Then check the sewer line on the same bill. Many utilities charge sewer fees based on how much water you use, even though pool water never goes down the drain. Some offer a pool-fill credit or adjustment if you call ahead, and some don't. A quick call to your water utility before you start can change the math a lot.

Also check for local watering restrictions. In a drought, some towns limit or ban filling pools from the public supply, which can make delivery the only legal option.

When a hose is a bad idea: wells and low pressure

If your home runs on a private well, think twice before filling a pool with a hose. A well can only supply water as fast as it recharges. Running it for a day or more can draw the water level down, stir up sediment, and in the worst case leave the pump running dry, which can damage it. You may also lose household water pressure while the pool fills.

Well water can bring its own problems too. Iron, copper and manganese are common in some wells and can stain plaster or vinyl when chlorine hits them. If you do fill from a well, test the water for metals and add a metal sequestrant before you shock. Our guide to potable vs. non-potable pool water covers what to look for.

Very low water pressure is the other dealbreaker. If your bucket test shows a slow trickle, a fill from empty could stretch over several days.

When a water truck makes more sense

• You're on a well or your well is shared or slow to recover.
• You need it fast, for example after a liner replacement, a repair or a drain-and-refill, when the pool shouldn't sit empty or half full.
• Your town restricts pool filling from the public supply.
• Your tap water costs more than you expected once sewer charges are counted.
• You want a known water source, such as potable water from a public system, instead of untested well water.

Most water trucks carry about 4,000 to 6,000 gallons per load, so a typical inground pool takes a few loads. Because the truck pumps the water in, each load goes in far faster than a hose. Ask the hauler how long each load takes and how many loads your pool needs, since the number of loads and the distance from their water source drive most of the price. Haulers usually also need a clear path for the hose from the driveway to the pool.

The hybrid approach

You don't have to pick just one. A common plan is to have a truck deliver most of the water and finish with a hose. That keeps the number of truckloads down, since you can top off the last few inches yourself instead of paying for a partly used load. Ask your hauler how they price partial loads before you decide.

If you are filling a brand-new vinyl liner, talk to your installer first. Installers often want the first few inches added slowly so they can smooth out wrinkles before the water gets deep, and some prefer a hose for that stage. A hauler can usually work around that if you tell them ahead of time.

After the fill: same steps either way

Whether the water came from a hose or a truck, test before you treat. Check free chlorine, pH, total alkalinity, calcium hardness and cyanuric acid (stabilizer), plus metals if the water came from a well or unknown source. Add a metal sequestrant first if metals show up, then balance alkalinity and pH, shock, and run the filter until the water is clear. Most pool stores will test a sample for free or a small fee.

Find a hauler near you

If delivery is the right call, compare a few local haulers. Browse haulers in Pennsylvania (including Philadelphia and York), Ohio (Columbus and Toledo), Martinsburg, West Virginia, Flint, Michigan, Riverside, California, Mesa, Arizona and Texas, or see every state and pool water delivery near me.
