Underground Tanks

Underground storage tanks (known as USTs) are typically constructed of Steel, Aluminum, Fiberglass or a combination of materials. They may be either single-wall or double-wall construction.

  • Uses include potable water, wastewater, fire protection, stormwater, petroleum products, chemical storage, and other waste.
  • Tanks are most commonly constructed of concrete, plastic, or fiberglass.
  • Concrete USTs may be poured-in-place or the design may utilize pre-fabricated walls. Sizes can easily reach a million gallons of capacity.
  • Plastic and fiberglass USTs are commonly round, oval, square, or oblong and generally available up to 50,000 gallons.  

Underground storage tanks (USTs) are popular when space is limited above ground or the tank needs to be hidden.
