This article highlights the port of Portland, Oregon, as a leading‐edge example of a decentralized ecological approach by its use of natural systems for wastewater processing at its new headquarters office facility at the Portland International Airport. As part of its ongoing focus on sustainable practices, the port decided to build its new offices using the Living Machine® ecological wastewater treatment and water reuse system that produces quality freshwater out of both gray and black water without the chemicals, odor, offensive byproducts, or high energy use required by conventional systems. The article describes the use of tidal wetlands systems to optimize the compact footprint of traditional wastewater treatment technologies with the energy efficiency of conventional constructed wetlands.
