Filling a Pool: Calculating the Cost per Gallon

The volume of water required to fill your pool post-installation depends primarily on its size and shape. You can easily calculate the gallons of water needed by following these formulas:

For Circular Pools:

Total Water Volume = Diameter Length (A) x Diameter Length (B) x Depth x 5.9

For Rectangular Pools:

Total Water Volume = Length (A) x Length (B) x Depth x 7.5

Note: If your pool has varying depths, calculate the average depth to determine its water capacity accurately. Maintaining a record of your pool’s dimensions simplifies this calculation.

Now that you know your pool’s total gallon capacity, you can estimate the cost of filling it by referencing your water bill.

Employ this basic formula:

Cost to Fill = (Pool Capacity in Gallons / 1,000) x Cost per 1,000 Gallons

For instance, if your water and sewer rate amounts to $9 for every 1,000 gallons consumed, and your pool holds 20,000 gallons, the calculation for filling your pool with municipal water would be:

(20,000 Gallons / 1,000) x $9 = $180

Different Pool Water Sources and Cost Variations

The process of filling a swimming pool can become more complex when you opt for well water or a water delivery service instead of relying on local municipal water. Here’s what you should take into account when choosing the source of water for your pool:

City Water

Using city water is the simplest and most cost-effective option, typically costing around $0.004 per gallon. For pool sizes ranging from 15,000 to 30,000 gallons, the cost generally falls between $60 and $120. Keep in mind that some regions, like California, may impose fines for excessive water usage due to drought concerns, so it’s essential to check with your local municipality before filling your pool.

Well Water

If you have access to well water, you might not receive water bills, but you will notice an increase in your electricity bill due to the power consumed by the well pump. To calculate the impact on your electric bill, you can use the formula (pool capacity in gallons/1,000) x cost per 1,000 gallons, considering the electricity rate from your utility provider. It’s important to have information about your well pump, including its manufacturer, wattage, age, and model. Well water is generally chemically stable, but it may require additional treatments. In some cases, mixing well water with transported water can be a cost-effective solution.

Water Delivery Service

Many pool owners opt for a local pool service to provide water for their pools. The cost will depend on the water supply source, the type of water, and the required volume. For a 30,000-gallon pool, you can expect to pay between $1,250 and $1,900 for water delivery service.

Partial Fills

When refilling a pool, it’s crucial to estimate its current water volume to prevent overfilling. Typically, for every 20,000 gallons of water, you’ll need to add an additional 1,000 to 3,000 gallons (or 15%) when refilling from a partial drain below the skimmer. Throughout the swimming season, you may also incur additional costs for maintenance water to compensate for water loss due to leaks, evaporation, and splashing.

Choosing the right water source for your pool filling needs involves considering factors like cost, availability, and the specific requirements of your pool to ensure it’s filled efficiently and cost-effectively.

Costs for Water Delivery Services

The expenses associated with water delivery services can fluctuate based on your geographical location. As a general guideline, water delivery costs typically fall within the range of $175 to $380 per delivery. To estimate the cost for your specific pool, you can use a straightforward formula, taking into account that most delivery trucks can transport up to 6,000 gallons of water per trip:

For a conservative estimate: (Your pool’s capacity in gallons/6,000) x $175 = cost

For a higher estimate: (Your pool’s capacity in gallons/6,000) x $380 = cost

By applying these formulas, you can quickly calculate the expected cost of water delivery services tailored to your pool’s size and specific needs.

You can calculate the cost of filling your pool per gallon by using a simple formula: (Pool capacity in gallons / 1,000) x Cost per 1,000 gallons. For example, if your pool holds 20,000 gallons of water and your water and sewer rate is $9 for every 1,000 gallons, the cost to fill your pool with municipal water would be (20,000 gallons / 1,000) x $9 = $180.

Here is a breakdown of the estimated costs for filling pools of various sizes:

  • 10,000-gallon pool: $90
  • 15,000-gallon pool: $135
  • 20,000-gallon pool: $180
  • 25,000-gallon pool: $225
  • 30,000-gallon pool: $270

Several factors influence the cost, including the water source. City water is usually the most cost-effective, while well water may increase your electricity bill. Water delivery services can range from $1,250 to $1,900 for a 30,000-gallon pool. Partial fills and maintenance water costs should also be considered due to water loss from leaks, evaporation, and splashing.

Water delivery costs typically range from $175 to $380 per delivery. You can estimate your specific cost using this formula: (Your pool’s capacity in gallons / 6,000) x Cost per delivery. This calculation takes into account that most delivery trucks can carry up to 6,000 gallons of water per trip.

When selecting a water source, consider factors such as cost, availability, and your pool’s specific requirements. City water is cost-effective but may have restrictions. Well water may save on water bills but can increase electricity costs. Water delivery services offer convenience but come at a higher price. Evaluate these factors to make an informed choice.

To avoid overfilling when refilling your pool, estimate its current water volume accurately. Typically, for every 20,000 gallons of water, add an extra 1,000 to 3,000 gallons (or 15%) when refilling from a partial drain below the skimmer. Additionally, be prepared for maintenance water costs to compensate for water loss throughout the swimming season due to factors like leaks, evaporation, and splashing.
