Highland Tank underground steel tanks provide superior structural strength,
product compatibility and durability. They are designed to withstand the rigors of
the underground environment and are serviceable for storage of a wide range of
petroleum products and other hazardous liquids. All of our tanks meet or exceed
the United States Environmental Protection Agency’s regulations for underground
storage of petroleum and chemical products.
Steel storage tanks have been shown
to be satisfactory for storing 100%
ethanol and E-blend gasoline. Steel
tanks have been used to store alcohols
for more than 50 years without
documented compatibility problems.
