Water Processing and Storage Tanks
Steel tanks fabricated to NSF 61 and AWWA Standards

Southeastern Construction fabricates steel water processing, water storage, and potable water tanks to NSF 61 standards. The National Sanitation Foundation’s standards help keep potable water in safe, drinkable conditions for the public. The NSF/ANSI Standard 61 signals that a product is safe to be installed in a potable water system for public use or consumption.
Steel water processing and storage tanks are also fabricated to AWWA standards by Southeastern Construction. The American Water Works Association standards describe minimum requirements for design, installation, performance, and manufacture of products used in the drinking water industry.
