Water Storage Tank Cleaning

Anytime you are storing water, a major concern for many customers is how to keep the water clean during storage. Depending on how long you are looking to store this water, this can include a variety of methods including tank colors, added solutions, and sanitizing.

Tank Exteriors

During water storage, growth of water borne algae can be problem, especially if your tank is being stored in an outdoor location. To handle the problem of outdoor storage or storage of tanks in areas particularly prone to light exposure, the first option to consider is using a tank with a darker exterior.

This method is often seen during the storage of water in plastic tanks. Since these tanks are commonly made from a poly material such as polyethylene, they are simply replaced with a black or dark green polyethylene alternative. This gives the tank the same FDA approval, while also blocking light from entering the tank and causing growth.

Tank Interiors

As a general standard, you should always make sure that the container you use to store your water is food-grade and approved for the storage of potable water. Containers of this type will usually include an FDA approval for the storage of drinking water and other food grade materials. In some cases, drinking water storage tanks will also contain an NSF 61 approval. NSF International in an independent organization committed to the public safety and storage of drinking water materials.

Long Term Water Storage

If you are planning on using a tank for long-term drinking water storage, it is often advised that some type of softener or water preserver be placed within the tank. These solutions can be found in various camping, RV or general and online stores and include elements that help to kill bacteria and mold to keep your water clean.

Most long term water storage preservers are designed to help you successfully store water for up to five years (5 years).

Sanitizing and Cleaning your Tank

Tanks can also be cleaned and washed out using a chlorine sanitizing solution. It is typically recommended that your chlorine solution is not more than 5%. More information on cleaning and caring for your tank can be found on the How to Clean a Water Tank page.
