What is underground water tank?

Underground water tanks are designed specifically for underground use based on their rotationally molded design and application. These tanks are often required for property owners who need water storage but cannot have a tank visible on the surface, or to preserve land use and space. Underground installation also protects the tank and contents from the effects of sunlight, which can be damage to the tank resin and microbiological growth.

These tanks are commonly constructed of high-quality, virgin polyethylene that is regulation-approved for potable (i.e. drinkable) water. Underground tanks work with a pump and pipe system to transport water in the storage tank to application areas. Underground water storage tanks are installed at a depth to protect them from freezing in areas that experience such temperatures.
