Griffin Electric Assists Huntsville Utilities on New Southeast Water Treatment Plant

Building Alabama

Nearly a year ahead of schedule, Huntsville Utilities recently completed its brand new Southeast Water Treatment Plant along Guntersville Lake in Grant, Alabama. Located across more than 250-acres, the treatment plant allows for a 96 million gallon-per-day total build-out capacity.

In addition to the main water treatment plant, other major aspects of the project included construction of a raw water intake structure, three pump stations, 42-inch raw water main, conventional mixing, flocculation, and filtration facilities, elevated backwash water storage tank, and a 48-inch finished water main.

Wayne J. Griffin Electric, Inc. (Griffin Electric) wired all electrical, standby power, security, instrumentation, and control facilities on site. Led by Calvin Mize, Region Manager, the Alabama Griffin team installed over 4-miles of 15 kV primary and communications ductbanks, cabling, and fiber between the main plant and the raw water intake facility. The plant is powered by two 1200 amp 15 kV, one 2000 amp kV and one 1200 amp 5 kV metal-clad lineups as well as a 2 megawatt backup generator.

Birmingham-based Brasfield & Gorrie was the general contractor assigned to the project, working directly with Tetra Tech, Inc. of Huntsville, which served as both architect and electrical engineer.
