what we do

Wastewater

Engineering innovative wastewater treatment solutions

Increasing population, aging infrastructure, and stricter regulations have put pressure on wastewater conveyance and treatment systems. Parametrix develops sustainable, cost-effective solutions. In addition to traditional approaches, we are experienced in designing systems for advanced membrane filtration, reclaimed water, enhanced nutrient systems, and biosolids management. From collection and conveyance to treatment and reuse, we are exploring new ways for our clients to improve their operations and meet today’s challenges.

Parametrix Wastewater - SE 83rd Pump Station, Portland, Oregon
SE 83rd Pump Station
​​Portland, Oregon
Client: ​​City of Portland Bureau of Environmental Services

This new pump station and force main provides sewer service for the Lents area of southeast Portland, a residential area historically served by septic tanks and cesspools. Parametrix designed the pump station, which features constant speed duplex submersible pumps, an outdoor standby generator, and a biofilter for odor control. Low impact development best practices were incorporated into the project. These features included an ecoroof covered building housing electrical equipment, pervious concrete pavement to minimize site runoff, and bioswales designed to manage stormwater from the street. The force main crosses Johnson Creek on the SE 82nd Avenue Bridge. Two air release/vacuum relief valves prevent air accumulation and protect the force main from water hammer. Expansion flexible ball-joints on the pipeline at each end of the bridge help protect the force main during seismic events.
