# How is Pool Occupancy Calculated?

Usually, residential pools are smaller than commercial pools. One of the objectives of commercial pools is to offer relaxation and entertainment to the public. Thus, these pools can be ten times bigger than a standard pool. You can find them in resorts, hotels, education, and recreational facilities. It is essential for pool owners to determine pool occupancy. This way, they can ensure safety for all users.

## Bather loads #

You can calculate your pool occupancy using various formulas. Different states have different methods for determining the occupancy. So, check the correct procedure of identifying your occupancy in your state offices. But if your state does not have one particular method of calculating bather loads, see the below general formulae.

## Pool occupancy formula #

In pools that are 1.5 meters or less, calculate pool occupancy based on one person occupying 15 square feet of the pool’s surface area. Also, do this for pools with a depth fewer than 5 feet.

Even so, before calculating the pool occupancy, deduct the surface area of the diving board from the total surface area. Diving board areas often occupy 300 square feet of the pool. Let’s look at a practical example. Suppose your pool’s total surface area is 1800 square feet, and the depth is 5 feet. Start calculating the pool occupancy by subtracting 300 from 1800. The remaining surface area of the pool is 1500. So, to estimate the occupancy:

1500 square feet divided by 15 square feet = 100

So, the maximum occupancy of your pool will be 100 people.

## How do I determine the surface area of my pool? #

Calculating the surface area of your pool incorporates a particular formula. Suppose you have a rectangular pool. Determine the length and breadth of your pool. Afterward, multiply both measurements. Let’s say your pool’s size is 90 feet long, and your width is 30 feet. Your surface area will be 2700 square feet.

## What if my pool is circular? #

Calculating the surface area of a circular pool entails multiplying the pool’s squared radius by the regular pie, which is usually 22/7. An oval pool usually has two radii. Calculating these pools’ surface area involves multiplying the first radius, the second radius, and the pie. To understand further, see the below calculations:

• Circular pool surface area = 22/7 *radius squared
• Oval pool surface area = 22/7 *first radius * second radius

## Summary #

Once you determine your pool occupancy, you will be able to know your bather displacement. As a result, you will be able to know the rate of water loss in your pool. Thus, you can buy the most effective pumps for your pool. Ultimately, you will be able to maintain a clean and healthy pool.
