At Spiess Construction Co., Inc., we specialize in the construction and renovation of welded steel tanks. Secure water storage has never been more important. Water use, water storage, water conservation are always current talking points and more frequently than ever in the news. Our communities need to protect their drinking water; fire departments and hospitals need a stable and survivable water supply; water district/agencies need reliable storage systems that are cost effective.

Over the years we have focused our concentration in the tank industry to welded steel tanks. The following are a few of the main advantages of the welded steel tank.

  • Welded Steel Tanks are inherently more resistant to earthquake damage than other tank types of equivalent-capacity with the same dimensions.
  • Tank dimensions and capacities are customizable and can be adjusted to the needs of the agency.
  • Long term maintenance such as recoating the interior lining or adding life-extending cathodic protection or is easier than other types of the tanks.
  • A well-maintained Welded Steel Tanks lifespan is 75 to 100 years.
