Many pool owners do not understand the importance of knowing the volume of water in their pool. Why is this knowledge essential? The answer is simple. When you know the volume of water in your pool, you know how much of your chemicals to add. Adding too little or too much can cause all sorts of problems. Has it been a while since you were in math class? No problem. Fronheiser Pools is going to show you how to calculate the volume of water in your swimming pool for accurate chemical adding.
The Basic Formula
To perform the basic calculation to determine the volume of water in your pool, you are going to need to know your pool’s measurements. For a rectangular pool, measure the length and width of the pool. Calculate the average depth of the pool by adding the shallow-end depth plus the deep-end depth and divide by two. Example: shallow depth is 3, deep end is 9. 3 + 9 = 12 ÷ 2 = 6. The average depth is 6. Here is the formula:- First, multiply Length x Width x Avg. Depth = X
- Next multiply X by 7.5, which is the number of gallons in one cubic foot of water
- L 30 ft X W 15 ft X Avg. D 6 ft = 2700 X 7.5 = 20,250 total gallons of water in the pool
