The Grand Valley Regional Biosolids Authority is a cooperative effort of the cities of Grand Rapids and Wyoming, Michigan, to manage their municipal wastewater biosolids. The Authority constructed a biosolids processing facility, which includes pipeline linkage, storage and dewatering of the biosolids. The facility was constructed in four segments.
Erhardt constructed the dewatering facility, which was the fourth and final segment of the project. Construction started April 2008 and was completed in 2010.
The project received U.S. Green Building Council LEED Silver certification™.
