About Us

Experience. Quality. Attention to detail.

Design Tanks is the premier manufacturer of fiberglass tanks centrally located in Sioux Falls, South Dakota.

Raven Industries started manufacturing fiberglass tanks more than 40 years ago. Raven grew into a company recognized internationally for its quality products. In 2000, it sold its tank manufacturing facilities—and Design Tanks was born. Almost all of the former Raven employees stayed with the new company, bringing their invaluable experience and eye for quality.

Today, the Design Tanks team of in-house designers and engineers will meet any technical requirements demanded for a customer’s storage container project. Design Tanks works with individual project specifications to develop a winning strategy.

The company specializes in custom-engineered fiberglass tanks, with a manufacturing and support staff that is flexible and committed to providing the best product at a competitive price.

Design Tanks takes great pride in its history in the fiberglass fabrication industry. The experience, quality, and attention it brings to the storage and containment industry is unparalleled.
