The new Process Building at the San Francisco International Airport Wastewater Treatment Plant increases the plant’s efficiency and capacity to handle wastewater produced by the airport and surrounding communities.
Located within 50-feet of San Francisco Bay, the building’s three-story height makes it one of the tallest, most visible objects in the area. MWA, therefore, gave the building a sculptural presence while simultaneously responding to the process and structural needs. The third floor houses a gravity belt press. The building highlights this primary function through its use of large glass planes, which reveal the press within while also reducing the amount of concrete and therefore the seismic loads. The first floor accommodates chemical storage and feed. The second-floor houses electrical and mechanical equipment for the press. The building is also designed to resist corrosion from the Bay atmosphere. It utilizes concrete and glass with a standing seam metal roof.
