Recycled water system serving the first LEED Platinum Port headquarters facility in the United States.

Puttman worked with the Port of Portland to implement an onsite wastewater treatment system to serve its new 200,000 SF, LEED Platinum headquarters building located at Portland International Airport.  Completed in 2010, the building is served by a 7,500 GPD living machine.  The system includes a collection system, primary tank, constructed wetlands, filtration, disinfection (chlorine), clean water tank and a non-potable water distribution system.

Living Machine

A Tidal Flow Wetland Living Machine® is the central design feature in the lobby and along the exterior front walkway of the Port of Portland Administrative Office Building. After collection and initial treatment of the wastewater in a primary equalization tank, the water flows to the Living Machine®. This system, utilized for secondary and tertiary wastewater treatment, is composed of six tidal flow cells and one vertical flow cell. The high quality treated effluent is filtered and disinfected with ultraviolet light and chlorine.
