LEARN HOW TO OPERATE YOUR PUBLIC POOL SPA FACILITY
Codes require more than one turnover per day:
The common accepted standards for one turnover are:
Pools - 6 hours
Spas - 30 minutes
Wading pools - between 1 and 2 hours
Therapy pools - 2 hours
Hospital and health club pools - as low as hours
To achieve the required Turnover Rate (TR), there must be sufficient flow of water or Flow Rate (FR)
Formula for Turnover Rate:
Divide the pool shape into areas of constant depth, or constant slopes.
Turnover Rate(TR) = Gallons divided by Flow Rate (FR) divided by 60.
Flow Rate (FR) is measured by a flow meter.
Example:
You have a 65,000 gallon pool, and the flow meter is reading
240 GPM (gallons per minute). What is the Turnover Rate (TR)?
Turnover Rate(TR) = Gallons divided by Flow Rate (FR) divided by 60
Gallons = 65,000; FR = 240 GPM
TR = ÷ ÷ 60 =
The standard for a swimming pool is 6 hours. This pool is well within the code standards.
Remember, Always operate in compliance with your local or state code requirements.
