Short Elliott Hendrickson Inc. (SEH), Champion Coatings, and Wapasha Construction took top honors in the inaugural Sherwin-Williams Impact Award program for their rehabilitation of a domestic anaerobic digester for the city of Austin, Minnesota. The challenging project impressed the program’s judges, who were looking to recognize notable projects featuring coating and lining materials from Sherwin-Williams Protective & Marine Coatings. The company announced the Impact Award winners at the Water Environment Federation’s WEFTEC conference on September 26, 2016, in New Orleans, Louisiana.

“We created the Sherwin-Williams Impact Award to honor demanding water and wastewater projects and recognize those professionals who contribute to improving public health and safety by enhancing water and wastewater infrastructure,” said Kevin Morris, Market Segment Director, Water & Wastewater, Sherwin-Williams Protective & Marine Coatings. “Award entries demonstrated project excellence in using high-performance protective coatings to address corrosion-related problems across a variety of water and wastewater structures, such as storage, transmission, and treatment facilities.”

Minnesota-based SEH, a multidisciplinary design firm with a focus in the water market; Champion Coatings, an industrial sandblasting and painting contractor; and Wapasha Construction, a general contractor specializing in wastewater treatment facilities, earned the Sherwin-Williams Impact Award for persevering through major challenges to restore two domestic anaerobic digesters for the city of Austin, Minnesota. The nearly 60- and 80-year-old digesters were severely deteriorated with numerous cracks in their covers that caused the tanks to lose pressure. Through careful consideration of the needed design criteria to solve the facility owner’s problem, SEH recommended the use of Sherwin- Williams Polyurethane Elastomer lining. Under challenging operating and weather conditions, the contractors successfully sealed the cracks using SherFlex Elastomeric Polyurethane to form a monolithic surface.

“SEH, Champion Coatings, and Wapasha Construction faced a lot of trial and error to properly seal the anaerobic digesters due to difficult-to-access areas within the tanks. Through engagement of all parties, their perseverance demonstrated the companies’ commitment to ensuring quality repairs to extend infrastructure life,” said Morris.
