WATER TREATMENT TABLES
VOLUME CALCULATIONS
Chemical adjustments are vital to proper sanitation and water balance.
Since adjustments are based on the volume of water in the pool or spa,
it is important to calculate the volume correctly. The following formulas
may be used:
1. Rectangular or square shaped pool
Example 1 (U.S. Customary Units):
length = 40 feet
width = 20 feet
avg. depth = 4.5 feet
volume = (length x width x average depth x 7.5)
40 x 20 x 4.5 x 7.5 = 27,000 gallons
Example 2 (Metric Units):
length = 12m
width = 6m
avg. depth = 1.5m
volume = (length x width x average depth x
1,000)
12 x 6 x 1.5 x 1,000 = 108,000 liters
