McCarthy Building Companies Inc. recently completed a $170 million Phase III expansion project at the Greenfield Water Reclamation Plant, located at 4400 S. Greenfield Road in Gilbert, Ariz. This project represents a 14 million gallon per day (MGD) expansion of liquids and solids treatment that allows the facility to treat up to 30 MGD of liquids and 38 MGD of solids on an annual average flow basis.
Three municipalities – the City of Mesa and Towns of Gilbert and Queen Creek – jointly own the treatment plant while the City of Mesa maintains and operates the plant. The original plant opened in 2007 and was constructed by McCarthy Building Companies in a joint venture with Sundt Construction.
Construction for the plant expansion started in November 2017 and reached substantial completion in August 2020, despite challenges this year with COVID-related restrictions on suppliers and subcontractors.
