SIZING IN GALLONS
Pre-Programming Requirements
A. Determine the Maximum System Flow Rate or Well Pump Flow Rate in Gallons
per Minute.
If well pump output is unknown, refer to example below:
Calculate well pump output rate (gpm).
Determine the output rate by opening a faucet until the well pump turns on.
Immediately turn off the faucet and time how long the well pump runs. Next,
measure the volume of water drawn from the faucet until the well pump turns
on again.
Volume of water until the pump turns on (gallon)
How long the pump runs (min.)
Example: After drawing 10 gallons of water,
the well pump took 2 minutes to fill the
pressure tank and stop.
B. Determine Solution Strength Percentage and the Dosage Requirement in Parts
per Million.
If dosage is unknown, refer to example below:
Calculate required dosage (ppm).
Refer to Oxidation Rates below. Estimate dosage and include the ppm of
required residual.

Example: To treat a water supply containing
2 ppm iron and 4 ppm hydrogen sulfide
with a chlorine residual of 1 ppm, a dosage
15 ppm of chlorine is required.
