The members of the STI/SPFA Field Erected Tank Section build steel tanks that meet or exceed the requirements of AWWA, NSF, API and industry standards. Members of STI/SPFA produce elevated, reservoir and standpipe water storage tanks. They also produce storage tanks for the petrochemical industry and special storage systems.
Tanks can be designed to hold from 50,000 to several million gallons, are provided with foundations, and often finished with elaborate painted graphics and color schemes. Tanks may incorporate cathodic protection and piping. Some water tank designs allow for several floors, office space and other facilities. Private, municipal, and industrial water system engineers and operators specify steel tanks for their reliability, long-term value, and low, predictable normal maintenance.
When selecting a steel storage tank, a comprehensive evaluation should be made of all the alternate designs available.
The STI/SPFA honors the owners of steel water storage tanks at least 100 years old and still in active service.
The STI/SPFA Product Awards recognize steel construction product achievements that exemplify the steel tank industry.
