How to Maintain Water Tanks in Southern California

Tuesday, July 16, 2013

Whether you own a water holding tank, portable water tank or other type of container, cleaning is essential for keeping water safe and drinkable. And yet, routine cleaning can be one of the most overlooked maintenance procedures in the potable water industry.

Sediment can form in the bottom of tanks, which promotes bacterial growth and the formation of  other contaminants. Removing any sediment buildup and regularly cleaning the tank ensures healthy water. Here are the steps to thoroughly cleaning your water tank:

  1. Drain (or don’t). Before cleaning, drain the tank completely. However, special cameras and sterilized divers can record conditions of interior paint and sediment level without draining the tank as well, but can be costly.
  2. Scrub. Using a stiff brush or high pressure jet, clean internal surfaces with a mixture of detergent and water. Pay extra attention to corners and joints where residue can build up easily. Then rinse, completely flushing tank with water for removal of detergent mixture.
  3. Disinfect. Depending on the type of water tank you own, create a concentrated chlorine solution in appropriate levels. It is typically recommended that the solution contain no more than 5% of chlorine. Let sit and flush tank once more.
  4. Think long-term. Some might find it beneficial to purchase a water softener or water preserver for more permanent water storage. If the tank needs to be replaced or requires a new coating, dark exterior tanks will prevent algae growth that occurs with light exposure.

If your tank needs other maintenance, such as lead abatement or a new coating of paint, you might want to consult a professional.
