Garney helped to build a new 24 MGD wastewater treatment plant including more than 30 facilities totaling over 300,000 SF of building footprint on an 90-acre project site. The sheer size of several of the facilities was a challenge. The headworks building was 50′ deep and was constructed of 60″ thick x 45′ tall walls.  The project was the largest progressive design-build project in the US at the time.
