About us

 Watco Tanks has been in the business of building shop welded tanks for over 50 years. During this time, we have pushed to meet all of our customers needs, including the API Type Oil Storage Tanks and the UL Approved Underground and Aboveground Tanks.

Watco, combining the most up-to-date equipment with skilled employees with years of experience, has become known as one of the leaders in steel tank fabrication.

Watco has a manufacturing space covering over 20 acres and a company owned trucking fleet.  

Through years of experience and customer satisfaction, we at Watco have come to know that you, the customer, demand and deserve the best product and service.  

Watco's reliability and quality, combined with our experience, give us the edge in satisfying your needs, no matter how big or small and we look forward to doing so.
