Cleaning of Tank (Temporary and Long Term Storage)
The tank is easily cleaned after normal usage.
With the tank empty and flat on the truck, partially fill it with 100
to 300 gallons of clean disinfectant and water solution. The solution
consists of 1/2 gallon of commercial bleach mixed in 250 gallons of
fresh water.
Surge the cleansing solution by walking back and forth on
the tank or by rocking the truck with abrupt starts and stops. The
resultant surge will clean or rinse the collapsed tank without exposing
its interior to contaminants or foreign objects.
Flush tank with 250
gallons of fresh water, surge as above and drain.
When the cleaning is complete, close the tank valve immediately to
hermetically seal out contaminants.
