Unit water storage
Disinfecting Method 1
(a) Chlorinate the water in the container to at least 100 ppm FAC.
(b) Run some solution through the valves and spigots.
(c) Keep all interior surface wet with the solution for at least 60 minutes.
(d) Drain the disinfecting solution into a sanitary sewer or other approved location.
(e) Rinse the container and spigots twice with potable water.
Disinfecting Method 2
(a) If either water or the required chemical are in short supply, use the following method.
(b) Prepare 5 gallon of water with a 100ppm chlorine solution.
(c) Using a long-handled brush, stick, or rod with a cloth secured to the end, swab the interior of the tank every 10 minutes or as often as necessary to keep the
walls wet for 1 hour.
(d) Run some solutions through the valves and spigot.
(e) Drain the accumulated solution.
(f) Rinse the container and spigots twice with potable water.
When is method 2 used
If either water or the required chemical are in short supply
Alternative procedure
(a) Chlorinate the water to 10ppm FAC.
(b) Hold for 24 hours
(c) Drain the disinfecting solution into a sanitary sewer or other approved location.
(d) Rinse the container and spigots twice with potable water.
