How Much Does It Cost to Fill an In-ground Pool with Water?

When owning a pool for the first time, one of the things to consider is how you’re going to fill it. Will you get a water truck to come in or use a garden hose? The answer to this question depends on quite a few factors, and the size of your pool plays a large role in that decision. It will also determine the cost of filling your in-ground pool. Below, we’ll provide you with what you need to know about filling your pool with water for the first time.

What is the Size of Your Pool?

Before you can begin determining how much it will cost to fill your in-ground pool with water for the first time, you’ll need to know its measurements. One of the easiest ways to find this information is by looking through your owner’s manual, as it should tell you roughly how many gallons of water your pool can hold. However, if you don’t have this information handy, you can do a quick formula to figure this out. First, you will simply measure each end of your pool, and those two numbers will be the length and width measurements within your calculations. Then, you will measure the depth of your pool, and if there is a deep end and shallow end to account for, then you’ll simply find the average depth. Once you’ve found these numbers, your equation will be Length x Width x Depth x 7.5. This will give you the approximate water volume that your pool can hold in gallons. Once you’ve determined your pool’s total water capacity, you can begin figuring out how much money it will cost to fill a pool of that size. 

Using a Garden Hose to Fill Your Pool

Both are great options, whether you want to fill your pool with a garden hose or have a water delivery truck fill it. A typical household will use around 12,000 gallons of water every month, so if your pool holds that many gallons or more, you can expect your water bill to at least double when filling it for the first time. This depends on the charge of dollars/gallon but will typically be around $100 – $200 dollars depending on your location and the size of your pool. If you’re considering using a hose to fill your pool for the first time, then it’s a good idea to call your water company to ask about the rate of filling a pool. They can give you an estimated cost because if you’re in an area with a water shortage or rationing, you could be charged extra for using that amount of water. In this case, you might not be able to use your hose at all to fill your pool with that much water, which is understandable. 

The upside of using a hose is that you already have it at your access, and you can simply pay for this expense with your bill at the end of the month. A downside of using a hose, however, is how long it will take to fill. The average garden hose will release about nine gallons of water every minute and about 540 gallons an hour. So, if your pool holds, say, 20,000 gallons of water, it will take about a day and a half to fill it, or approximately 37 hours. 

Although this might not be the ideal situation for filling your pool for the first time, that’s not to say you can’t use your garden hose to add water to your pool every so often if you see it’s getting a bit low.

Using a Water Truck Delivery to Fill Your Pool

The alternative approach to filling your pool for the first time would be hiring a water truck to come in and fill it. Going this route is fairly straightforward and worry-free, as you will hire a business within your area to come to your home and do all the work for you. A typical water truck can hold between 6,000 – 9,000 gallons of water and can fill your pool within a few hours. However, it’s best to determine how many gallons of water your pool can hold before scheduling a delivery. You might need to have one or two truckloads come in, depending on the size of your pool. On average, you’re looking at between $170 – $350 dollars per truckload.

Many people will find that a water truck is their ideal option because it ends up being about the same cost to fill their pool within a fraction of the time. Not only will your pool be ready much faster, but you also know exactly what you’re paying for it as it’s happening. Because just as we mentioned before, you could be living in an area where the cost of using that much water will end up being even more than you assume it will be. So regardless of the option you choose, we recommend always doing a bit of research within your specific city to ensure that there are no surprise costs down the line.
