The city of Portland, Ore., is an extremely progressive city in terms of environmental quality. With that in mind, city planners teamed up with Portland’s largest employer, the Oregon Health and Science University, and two development companies to build a dense urban green neighborhood.
This 400,000-sq-ft, 16-story building cost $145 million to build and was completed in fall 2006. Despite being a green building, the project team believes it was built on a conventional construction budget.
Among many energy and water conservation programs, the OHSU building recycles 100% of wastewater generated. It is reused for in-building toilet flushing, cooling tower water and landscape irrigation. The OHSU building uses approximately 60% less potable water than a similar conventional building with the help of an Enviroquip MBR system . Effluent not reused can be discharged directly to the Lower Willamette River because of the Level IV reuse water produced by the MBR system.
The OHSU River Campus One building has achieved LEED Platinum status. To date, it is the largest LEED Platinum certified building in the U.S. The Enviroquip MBR System was selected because of its superior effluent quality, small footprint, ease of operation, expandability, low odor, low sludge production and low cost of ownership. This system contributed three points toward the building’s Platinum status.
Before the expansion, the plant regularly handled flows in excess of design. According to Ken Johannes, the plant operator, “Inflows from the building are higher than was originally modeled, with weekday average daily flows at currently about 165% of plan. The two MBRs have performed outstanding.”
