How Much Will It Really Cost to Fill Your Pool? Let’s Dive In.

The short answer? Filling a pool can cost anywhere from $4 to $400, depending on several factors. This wide range is due to variations in pool size, water source (municipal vs. trucked), and local water rates. Let’s break down these factors and explore how to estimate the cost of filling your pool accurately.

Understanding the Key Cost Drivers

Before we calculate, it’s crucial to grasp the elements that influence the final bill. Ignoring these can lead to nasty surprises!

Pool Size and Volume

Obviously, a larger pool needs more water. Pool volume is typically measured in gallons or cubic feet. To calculate the volume:

• Rectangular Pools: Length x Width x Average Depth x 7.5 (gallons per cubic foot)
• Circular Pools: π (3.14) x Radius² x Average Depth x 7.5
• Oval Pools: (Length x Width x Average Depth x 7.5) x 0.89

Accurate measurements are paramount. A slight miscalculation can translate into a significant difference in the amount of water needed.

Water Source: Municipal vs. Trucked

This is where costs can drastically diverge.

• Municipal Water: This is the water you get from your city or town’s water supply. It’s typically the cheapest option, charged by the gallon or cubic foot. Check your latest water bill to find your rate. Rates vary significantly by location.
• Trucked Water: If your well can’t handle the volume or you don’t have access to city water, you’ll need to hire a water trucking company. This is significantly more expensive, as you’re paying for the water and the transportation. Expect to pay a flat fee per truckload (usually a few thousand gallons). Prices depend on distance, truck size, and availability.

Local Water Rates and Usage Tiers

Municipal water isn’t free, and rates fluctuate.

• Water Rates: Check your local utility’s website or call them directly to find out the current rate per gallon or cubic foot. Many cities have seasonal rates, with higher prices during the summer months when demand is high.
• Usage Tiers: Some municipalities use tiered pricing, where the price per gallon increases as you use more water. Filling a pool might push you into a higher tier, making the last gallons more expensive. Be aware of your city’s tier system!

The “Hidden” Costs: Chemicals and Potential Leaks

Filling the pool is just the first step.

• Initial Chemical Treatment: You’ll need to balance the water chemistry after filling the pool, adding chemicals like chlorine, pH adjusters, and alkalinity increasers. Factor in an additional $50-$200 for these supplies.
• Potential Leaks: Filling a pool might reveal hidden leaks. If you notice the water level dropping rapidly, address the leak immediately to avoid wasting water (and money). A small leak can become a big problem, quickly.

Calculating the Cost: A Step-by-Step Guide

Now, let’s put it all together.

1. Calculate Pool Volume: Use the formulas above. Double-check your measurements.
2. Determine Water Source: Decide whether you’ll use municipal or trucked water.
3. Find Your Water Rate: Check your water bill or contact your local utility.
4. Calculate the Cost (Municipal Water): Pool Volume (in gallons) x Water Rate (per gallon) = Estimated Cost
5. Calculate the Cost (Trucked Water): (Pool Volume (in gallons) / Truck Size (in gallons)) x Truckload Cost = Estimated Cost. You may need to round up to the nearest full truckload.
6. Add Chemical Costs: Estimate $50-$200 for initial chemical treatment.
7. Contingency Fund: Always add a buffer for unexpected issues (leaks, higher-than-expected water usage). 10-15% is a safe bet.

FAQs: All Your Pool Filling Questions Answered

Here are some frequently asked questions to help you navigate the pool filling process:

1. How Long Does It Take to Fill a Pool with a Garden Hose?

It depends on the hose’s flow rate and your pool’s size. A standard garden hose delivers around 8-12 gallons per minute. A large pool could take several days to fill. Patience is key if using a garden hose.

2. Is It Cheaper to Fill My Pool with a Hose or Have Water Trucked In?

Generally, municipal water (hose) is cheaper if available and your well can handle the demand. However, if your well runs dry or you lack access to municipal water, trucking is the only option. Compare the total cost, including water rate increases.

3. Can Filling My Pool Affect My Water Pressure?

Yes. Filling a large pool draws a significant amount of water, which can temporarily reduce water pressure in your home and potentially in your neighborhood. Inform your neighbors if you anticipate a long fill time.

4. What Time of Day Is Best to Fill My Pool?

Filling during off-peak hours (late night or early morning) can minimize the impact on your home’s and neighborhood’s water pressure. Avoid peak usage times, like when people are showering or running sprinklers.

5. Should I Cover My Pool While Filling It?

No. Covering the pool won’t significantly reduce evaporation during the filling process, and it might actually make it harder to monitor the water level. Leave it uncovered for easy observation.

6. How Do I Know If I Have a Leak While Filling My Pool?

Monitor the water level closely. If it drops significantly faster than expected, you likely have a leak. Turn off the water and investigate. Look for wet spots around the pool’s perimeter and equipment.

7. What Happens If I Overfill My Pool?

Overfilling can damage the pool’s coping and surrounding deck. It also wastes water. Turn off the water as soon as it reaches the desired level.

8. Do I Need a Permit to Fill My Pool?

Some municipalities require permits for large water usage. Check with your local water department to ensure compliance. Ignoring permit requirements can result in fines.

9. How Often Should I Completely Drain and Refill My Pool?

Generally, you shouldn’t need to drain and refill your pool completely unless there’s a major contamination issue or the water chemistry is severely out of balance and uncorrectable. Partial draining and refilling (dilution) is often sufficient. Consult a pool professional before a complete drain and refill.

10. Can I Use Well Water to Fill My Pool?

Yes, but test your well water first. Well water can contain minerals (like iron) that can stain your pool. You might need to pre-treat the water before filling. Avoid using well water without testing it first.

11. How Soon Can I Swim After Filling My Pool?

You can swim once the water is properly balanced and sanitized. This typically takes 24-48 hours after adding chemicals. Test the water before swimming to ensure it’s safe.

12. What Is the Best Way to Prevent Water Loss in My Pool After Filling?

Use a pool cover when the pool isn’t in use to reduce evaporation. Regularly check for and repair any leaks. A good pool cover is an investment that pays off in water savings.

Filling your pool doesn’t have to be a financial drain. With careful planning and accurate calculations, you can minimize costs and enjoy your backyard oasis without breaking the bank. Remember to consider all the factors, from pool size to water source, and always have a contingency plan in place. Happy swimming!
