What is a potable water storage tank?

Potable water tanks are containers specifically designed for the safe storage of drinking water. They require certification from local regulatory bodies and specialized internal liners to protect the purity of the tank's contents.

With aboveground and underground options, plus capacities ranging from 1,000 to 250,000 L, our lineup of potable water storage tanks is the solution of choice for homes, businesses, and communities.

How do our potable water storage tank work?


Drinking water is stored in a leak-proof tank installed on the property or inside a building.

Depending on your needs, the system can be equipped with a flanged cover that seals the tank's contents from external contaminants. It can also be fitted with an overflow outlet that eliminates the risk of surcharges.

Potable water use

The storage tank can be configured to provide drinking water by way of gravity or a pump. Whichever set-up you prefer, the tank's water outlet can be easily connected to other on-site components as needed.
