Ironhouse Wastewater Treatment Expansion

This extensive expansion of the Ironhouse Sanitary District Wastewater Treatment Plant is located in the City of Oakley, adjacent to the marshlands of the San Francisco Bay Area Delta. The project included a new Headworks, Chemical/Electrical Building, solids handling facility, UV disinfection, membrane bio reactor and anoxic aeration basins.

A palette of exterior materials and finishes appropriate for each building type was developed to create a ‘campus’ of easily maintained and durable structures with materials and massing reflective of the agrarian context of the site.
