Flow Rate Sizing
For sizing flow rates, there are three parameters that need to be determined to appropriately size a system:
• Flow
• Peak Flow
• Continuous Flow
Average Flow
This can be calculated based on the daily or monthly volume of water used, divided by the number of hours the facility is
in operation.
EXAMPLE:
The average flow would be:
Monthly Water Bill Usage: 47,953 gallons
Open 7 days / week
Open from 6 am – 10 pm (16 hours/day)
47,953/30 = 1,598/day
1598/16 = 99.9/hour
50/60 = 0.8 gpm average flow
Peak Flow
The application's peak flow rate could be calculated in many different ways. The most reliable is to base the peak flow
rate on the incoming water supply.

Continuous Flow
Continuous flow can take on many different definitions. For the application of our equipment, continuous flow is defined
as the maximum flow average during a regeneration period.
EXAMPLE
For the CC Series, the regeneration period is about 11 minutes. Therefore, understanding the maximum amount of
water that is needed during any 11 minute period needs to be defined. Most appliances and devices use water in an
intermittent period, and do not substantially affect this continuous flow requirement.
Devices that need to be considered include
• Volume of a boiler blow down
• Large tank fills
• Continuous rinsing applications
• Irrigation needs
