If your underground storage tank holds 110 gallons or less, it is not subject to federal regulations, according to the Environmental Protection Agency. Due to this fact, the cleaning of these tanks and tank liners could be lax for some. This shouldn’t stop you from giving your liner the best cleanliness possible. Here are some of the best practices for this process.

Prepare The Area

Because water tanks tend to hold all kinds of water, the buildup from this water tends to linger in the tank. If you use tank liners for water systems, this increases the sanitation level. Although it must still be cleaned, you will have a much easier time addressing build-up with a liner than without one. In this way, clearing the area of any silt that may have gathered inside the tank will enhance your cleaning process. Seek out any debris and be sure to protect your feet with solid non-slip footwear.

Pressure Washer

For the next portion, you can apply the powerful cleaning qualities of a pressure washer. Be sure to turn the pressure down a notch or two before you begin. Adding household detergent to the mix is a good idea if you’d like to ensure a deeper clean. While rinsing the interior of your tank liner, you will notice that using a pressure washer ensures you do not damage your tank liners for water systems in some way. When it is set to the correct pressure, this method will leave you with a spotless liner.


If you do not have a pressure washer, a hosepipe and a soft mop will do the job just as well. This method will, however, require you to be slightly more cautious about the pressure you apply to the liner as you clean it. With a mop, it is possible to damage the liner if any sharp or hard edges on the mophead come into contact with the liner. With caution, you can hose down the interior side of the liner and use the mop and detergent to gently clean the buildup away from your tank liners for water systems.

Before Refilling

It is important to ensure the tank is completely emptied of any of the water used in the cleaning process before you refill it. You should flush it out well and ensure there is nothing that could contaminate the water.
