U.S. Department of Energy Advanced Wastewater Treatment (AWWT), FERNALD, OH

Mechanical Construction & Installation Services

DEBRA-KUEMPEL VALUE DELIVERED

DeBra-Kuempel helped restore drinkability to a 10-trillion gallon,1,050 acre aquifer, 5.8 billion gallons of which had been contaminated by nuclear waste; provided this value an estimated 15 years ahead of schedule, helped protect a major natural resource and enable it to continue to supply water for much of southwestern Ohio.

MECHANICAL CONSTRUCTION SCOPE OF WORK

These included mechanical installation of a new aeration tank and blower with all associated piping, as well as six ion exchange filter vessels and four multimedia filter vessels. Using drawings with approximately 2,000 separate line numbers, the company also fabricated the majority of the mechanical piping. This eliminated most field position welds.

WASTEWATER TREATMENT FACILITY BACKGROUND

Headquartered in Washington, D.C., the Department of Energy's mission is to advance the national, economic, and energy security of the United States; to promote scientific and technological innovation in support of that mission; and to ensure the environmental cleanup of the national nuclear weapons complex.

With an overall wastewater treatment design capacity of 2,900 gallons per minute, the Fernald AWWT facility is a major component of the extensive decontamination system built to extract, move, hold, treat and discharge or reinject treated water at this site.

MECHANICAL CONSTRUCTION & INSTALLATION SERVICES OBJECTIVES

To increase the speed with which nuclear contamination could be removed from -- and water purity restored to -- the Great Miami (OH) aquifer, one of the nation's largest aquifers and a primary source of drinking water for much of this region.

MECHANICAL CONSTRUCTION & INSTALLATION SOLUTIONS

DeBra-Kuempel saved the client money in several ways. A recommended mechanical pipe specification change reduced costs by approximately $100,000, while a recommended new resin for the ion exchange filters saved an additional $150,000 for the initial resin charge and a similar amount for each resin change out.
