Filling a swimming pool is a critical task that requires attention to detail, expertise, and the right resources—especially if you’re dealing with a newly constructed pool, a seasonal refill, or a repair-related drain. While it might seem straightforward, the process involves more than just opening a water valve. Most homeowners turn to professional companies to handle the job, but understanding the costs and variables involved can help you make a more informed decision.
This article will explore everything you need to know about hiring a company to fill your pool, including the average cost, influencing factors, types of service providers, and tips to ensure you get the best value for your money.
What Does “Filling a Pool” Mean?
Before we dive into pricing, it’s important to clarify what pool filling entails. Filling a pool refers to the process of adding clean, potable water into your swimming pool. While this may sound simple, the method and cost can vary depending on the size of your pool, the source of the water, and whether additional services (like filling after repairs, winterizing, or even saltwater conversions) are required.
In many cases, homeowners use their garden hose to fill a pool. However, this can take days and lead to a significantly higher water bill. To save time and sometimes money, more and more people are turning to companies that offer professional pool filling services.
What Is the Average Cost to Fill a Swimming Pool?
The average cost to have a company fill your pool can range from $200 to $1,000, but larger pools or those requiring additional services (like delivery from a distance or treatment after filling) can cost $2,000 or more. The final expense depends on several factors:
- Pool size and volume
- Distance from water source
- Water supply cost in your area
- Delivery method: hose from municipal supply or truck delivery
- Need for filtration or sanitization services
Let’s break down each of these to gain a comprehensive understanding of how the total cost is determined.
1. Pool Size and Water Volume
The most significant determinant of cost is the size of your pool. Pool volume is measured in gallons, and the gallon count directly affects how much water you need and how much you’ll pay.
| Pool Type | Average Volume (Gallons) |
|---|---|
| In-ground rectangular pool (16’ x 32’) | 18,000–25,000 |
| In-ground oval pool | |
| Freeform in-ground pool | |
| Small inground pool (12’ x 24’) | 10,000–15,000 |
| Large luxury pool (20’ x 40’ or larger) | 30,000+ |
| Typical above-ground pool | 12,000–16,000 |
The national average cost of water in the U.S. ranges from $2.00 to $6.00 per 1,000 gallons, though prices can be significantly higher in drought-prone states like California or Arizona.
For example:
- A 20,000-gallon pool in an area where water costs $4.00 per 1,000 gallons would cost around $80 just for water through a metered system.
- If water has to be trucked in, the cost per gallon can increase to **$0.10 to $0.50**, leading to total costs of **$2,000 to $10,000 or more**.
2. Methods of Pool Filling
There are two primary ways professionals can fill your pool:
- Municipal Water Hookup: Most companies hook up hoses directly to your home’s water supply or city main and connect them to your pool. This is usually the most economical method.
- Water Delivery Truck: In remote locations, areas under water restrictions, or where water isn’t easily accessible, companies may use water delivery trucks. These often come at a premium due to transportation and resource costs.
Municipal Water Filling
Also known as “hose fill” or “direct fill,” this is the most common and preferred method by pool owners due to its affordability. The service company connects large-diameter hoses from a metered point in the city water supply (often with permission from local authorities) and fills the pool over several hours.
Pros:
- Fast
- Cost-effective
- Water quality is typically high
Cons:
- Only available in areas with accessible city water
- May impact local water restrictions during droughts
Water Delivery Truck Fill
In this method, specialized water trucks bring water to your pool from offsite locations. The price starts at around $200–$300 for smaller trucks and increases with volume and distance.
Pros:
- Works in remote or drought-affected areas
- Minimal impact on household water supply
Cons:
- More expensive per gallon
- May require multiple trips for larger pools
3. Water Restrictions and Local Regulations
Many regions, especially in Western U.S. states such as California, Nevada, and Arizona, have imposed water usage restrictions due to prolonged droughts. These regulations can affect whether companies are legally allowed to fill pools using direct municipal water and may force the use of more expensive alternatives.
In such cases, companies must follow strict guidelines—such as applying for water usage permits—to legally perform pool fills, which can add both time and cost to the service.
4. Service Provider Type
The cost can also vary depending on which type of company you choose:
- Independent water delivery companies
- Pool maintenance and service companies
- Water utility contractors with pool services
Larger companies often bundle pool filling with other services like saltwater start-ups, initial filtration setup, or chemical balancing, which can add value or complexity to pricing.
Detailed Cost Breakdown by Pool Type
Pool size and type significantly influence the total cost of professional filling. Below is a general breakdown of expected costs based on common residential pool configurations.
In-Ground Pools
An average-sized in-ground pool (32’ x 16’) holds approximately 20,000 to 25,000 gallons.
Using municipal water at $4.50 per 1,000 gallons:
- 25,000 gallons x $0.0045 = $112.50 water cost
- Service labor fee: $200–$400
- Total: $300–$500
If fill is through a water truck:
- 25,000 gallons x $0.25 = $6,250 water delivery
- Service labor fee: $200–$500
- Total: $6,500–$7,000+
Above-Ground Pools
Above-ground pools typically range from 12,000 to 16,000 gallons.
With municipal supply:
- Water cost: $50–$70

Water truck delivery:
- 40,000 gallons x $0.30 = $12,000
- Service fee: $250–$600
- Total: $12,250–$13,000+
Factors That Influence the Final Price
Beyond the basics of pool size and type of service, several other elements can increase or reduce the overall cost. Understanding them can help avoid surprises and identify where potential savings may exist.
Geographical Location
Pricing per gallon of water varies substantially depending on where you live. In states like Texas and Florida, water is relatively cheap and abundantly available, making municipal filling especially affordable. In contrast, areas like Southern California or Colorado’s Front Range often face higher water costs and regulatory hurdles.
Taxes or Municipal Fees: Some cities charge additional taxes for large-volume water use or impose permit fees for pool filling.
Time of Year
Pool filling is often seasonal. The busiest months for pool services are between April and June, when homeowners prepare for summer and install new or seasonal pools.
During peak season, companies may charge a premium, while scheduling during off-peak periods (like fall or early spring) can offer better deals or faster availability. Some companies even offer early-bird discounts or package deals during slower seasons.
Additional Services (Optional or Required)
Some companies provide fill-only services, while others bundle water delivery with pool startup services like:
- Filter system priming
- Chemical balance setup
- Metal content testing
- Chlorination
- Equipment startup assistance
- Sludge removal if pool drained
These additional services can add $50–$300 to the final bill. While they’re technically optional, they’re usually worth the small investment for proper pool care and sanitation.
Site Accessibility
If your property is difficult to access due to uneven terrain, narrow gates, or a lack of road access near the pool, this can impact the service duration and labor costs.
Companies may charge extra for:
- Hand-hauling hoses long distances
- Setting up multiple connection points
- Managing difficult terrain or hazards
Water Quality and Filtration
Water directly from the municipal system may meet local standards but might have high levels of metals, hardness, or chlorine. Some pool owners opt to have the company install inline filters to prevent long-term scaling and staining. Expect an added $50–$150 for this service, depending on system complexity.
Distance from Water Source
Even if using a municipal supply, the distance from the pool to the nearest access point can influence labor and material costs. Short distances (within 50 feet) usually keep the pricing standard. However, if the nearest meter is two or three yards away and requires long hose runs over sidewalks, lawns, or through windows, companies might charge a small fee (e.g., $50–$150).
Hiring a Pool Filling Company: What to Look For
Not all companies are created equal, and choosing the right provider can save you money and hassle. Here’s what to consider before making a hire.
Licensing and Insurance
Ensure the company has the appropriate licenses for water work and public infrastructure use. General business licenses are standard, but some localities require water distribution permits.
Also, verify that the company carries liability insurance. In case of property damage—like broken sprinklers, soaked landscaping, or water line damage—you want to avoid being held financially responsible.
Reputation and Reviews
Search for the company online and read reviews on multiple platforms such as:
- Google My Business
- Yelp
- HomeAdvisor
- Angi (formerly Angie’s List)
- Facebook marketplace
Also, ask for references from neighbors or friends who have had their pools filled recently.
Transparent Pricing
A reputable service provider should break down their charges and clarify whether they’re charging by:
- Gallonage
- Hours of labor
- Flat rate
Some companies will offer free estimates or provide a detailed quote based on your pool size and location.
The best contracts clearly state the scope of work and include:
- Volume of water to be supplied
- Hourly or total fee
- Service start and end time
- Any minimum charges
Avoid companies that promise low prices with ambiguous fine print.
Cost-Saving Tips When Filling Your Pool
Here are several practical and effective ways to reduce the expense of pool filling while still ensuring a high standard of service.
1. Call in Advance
Scheduling your fill well before the busy season can help you avoid peak pricing and ensure faster access to the best companies. Many pool owners schedule in early spring to get started before April, when the biggest demand kicks in.
2. Use Your Own Water Supply
If your local water utility allows it, consider using your own hose to fill the pool. The direct cost per gallon is usually much lower, and it’s free if no meter is involved. However, this can take up to several days and may affect your household’s daily water use.
3. Group with Neighbors
Some companies offer discounts if they fill multiple pools in one trip. Ask neighbors to pool their resources and schedule a bulk refill. This can reduce travel costs for the company and create a better deal for everyone.
4. Opt for Partial Fills
If you’re topping off your pool after winter or a drought period, many companies offer lower rates for partial fills. Water trucks can often be booked for just half or three-quarter loads, allowing you to pay only for the necessary amount.
5. Understand Water Restrictions
Check with your local water authority to understand current and coming restrictions. Booking a fill just before a ban or price hike can be more economical and ensure your pool is ready for swim season.
Additional Considerations
Here are a few final factors that could affect your decision or experience when hiring a company to fill your pool.
Type of Water Treated
If your water is particularly hard or alkaline, consider whether the company can provide treated water. While it may cost extra, it could prevent chemical imbalances and future scaling inside the pool.
Saltwater vs. Freshwater
If you have a saltwater pool, the company may need to provide freshwater for the system to generate salt. Understand that the pool isn’t actually filled with saltwater—just water with added salt content. Clarify whether the provided startup water meets the chlorine generator’s requirements.
Water Conservation Trends
With growing concerns over water usage and environmental sustainability, you may prefer a company that sources water responsibly or uses water-saving practices. Some are even beginning to offer greywater treatment or conservation fill methods.
Aftercare and Initial Testing
Once your pool is filled, the water will need an initial balancing of chemicals. Some companies offer this service included in the package. If not, plan to test with a pool supply service or kit just a few days post-fill.
Conclusion
The cost of hiring a company to fill your swimming pool depends on a variety of factors, including pool size, water source, location, service provider, and additional regulatory or logistical challenges. On average, you can expect to spend anywhere from $200 to $1,000 for a standard residential pool, though larger or remote-filling projects may cost more.
By understanding the cost structure, pricing trends, and key selection criteria for service providers, you can make a more informed decision that matches your budget and your pool’s needs. Remember: while cost is a major factor, reliability, service time, and water quality are just as crucial for long-term enjoyment and trouble-free pool ownership.
Whether you’re filling a brand-new pool, starting the season, or refilling after repairs, taking the time to research your local providers, understand average costs, and plan in advance can help you make the most of your investment—not just in the filling process, but for the entire swimming season ahead.
What factors influence the cost of having a company fill my pool?
The cost of having a company fill your pool is influenced by several factors including the size of your pool, the distance of the service provider from your location, the water source used, and any additional services required. Larger pools require more water, which increases both the volume cost and the time needed for delivery and setup. Companies may charge extra if they have to travel a significant distance to reach your property, especially if they are using specialized equipment like water tanker trucks.
Another significant element is the water quality and source. Some companies may offer filtered or treated water, which can be more expensive than untreated water. In certain regions, local regulations or water scarcity can also affect pricing. Furthermore, if your location has restrictions on using municipal water, you may have to rely on alternative sources, which can affect the total price. Additional fees for labor, equipment rental, and service speed can further influence the final amount you pay.
What is the average cost of professionally filling a swimming pool?
On average, professional pool filling can cost between $200 and $1,000 depending on the gallons required and the factors previously mentioned. Smaller pools or spas can cost less than $200, while large in-ground pools with a capacity over 20,000 gallons can easily reach the higher end of that range, sometimes surpassing $1,000. Some companies charge per 1,000 gallons, with rates generally ranging from $10 to $30 per 1,000 gallons depending on water source and location.
It’s important to note that prices may also be subject to local water pricing fluctuations, transportation fees, and service scheduling. Many companies may offer lower rates for bookings during off-peak times or for customers who sign up for multiple services. It’s wise to compare quotes from multiple providers and confirm what’s included in the estimate—such as water quality testing, hose rental, and labor charges—before committing to a service.
Can I save money by filling my pool myself instead of hiring a company?
Filling your pool yourself can help reduce costs, especially if you have access to a municipal water source or a well. Using your own garden hose and tap water typically costs less per gallon compared to hiring a service; however, this can take anywhere from 8 to 48 hours or more depending on the size of the pool and your water pressure. In these cases, the main expenses are the time and potential water bill increase. That said, this method may not be feasible if your water source is limited or you lack appropriate equipment or access.
Additionally, DIY filling might lack the benefits professional services provide, such as water filtration, chemical balancing, or labor assistance. While you may initially save money on labor, you could end up spending more on water bills or facing potential issues like mineral deposits or imbalanced pH if the water isn’t treated. If you’re uncertain about the quality of your tap water or have a large pool, it may be more cost-effective in the long run to use professional services to avoid complications and additional expenses.
Are there any hidden fees when hiring a company to fill your pool?
Yes, there can be hidden or additional fees when hiring a company to fill your pool, such as delivery charges, setup fees, overtime costs, or equipment rental fees. Depending on the location and accessibility of your pool, the company may charge extra if they need to run long hoses, navigate difficult terrain, or work outside regular business hours. Additionally, some services may include water testing and balancing in their base price, while others may charge extra for those services if you request them.
It’s crucial to ask for a detailed quote before scheduling the service to avoid surprises. A reputable company should be transparent about any additional costs related to the job. Also, consider checking reviews or asking for referrals to find a company that is known for fair pricing and clear communication. Always ask if tax, disposal fees, or environmental surcharges are included in the total quote you’re being provided.
Will having my pool filled by a company affect my water bill?
Using a company that delivers water from a municipal source can still impact your water bill, especially if they charge based on meter usage rather than a flat rate. Some pool filling companies use their own water supply, such as from wells or reservoirs, and provide a fixed price, which means your water bill remains unaffected. However, if they use your home’s water supply via metered delivery, the additional usage will be added to your bill, which can be particularly costly in areas with high water rates or tiered billing systems.
You should ask the service provider upfront whether they will use your water meter or their own source. In some cases, companies apply for a utility discount or bypass the water meter charge with a hose attachment that doesn’t track usage on your account. Confirm these details in advance to avoid unexpected increases in your utility bill. If your water bill could increase significantly, compare the overall costs—including meter fees—between multiple companies to find the most economical option.
How does the pool filling process work when done professionally?
The professional pool filling process typically starts with a consultation where the service provider reviews the size and location of your pool and determines the best source and method of delivery. Then, equipment like water tanker trucks or long hoses from an off-site reservoir are brought to your home. The company sets up the required hoses and pumps, ensuring that the water flows efficiently into your pool. During this time, they may also use filters to ensure the water is clean and suitable for swimming purposes.
Once the filling begins, the technician monitors the process and ensures everything is functioning properly. If requested, they may also perform water testing and initial chemical balancing to help prevent future maintenance problems. The process can take a few hours to a full day depending on the pool’s size and water pressure. Once completed, the company removes all equipment and leaves the area clean. Some services offer follow-up visits to check water chemistry and ensure the pool is ready for use.
What should I look for in a professional company to fill my pool?
When choosing a company to fill your pool, look for a licensed, insured, and experienced provider that offers transparent pricing. Check online reviews and request references to ensure reliability. It’s essential to confirm that they offer water source options—whether municipal, well, or filtered—and have the equipment and capacity to handle your specific pool size and location, especially if you have unique challenges like limited access.
Additionally, inquire about the services they include in their package, such as water testing, pH balancing, setup, and cleanup. A trustworthy company should be able to clearly explain what their pricing covers and whether any additional fees could apply. Responsive communication, eco-friendly practices, and flexibility in scheduling are also important traits. By taking the time to research your options carefully, you’ll find a dependable professional pool filling service that delivers quality results without unnecessary financial or logistical stress.
