Water Reclamation Facility

May contain: building, vegetation, plant, outdoors, and nature

Operational Permits: NPDES

Oak Lodge Water Services operates the water reclamation facility under a National Pollution Discharge and Elimination System Permit (NPDES)

Service Area

The District estimates the average service population to be approximately 28,000. Growth is predicted to continue through build-out of the area but the rate of growth will be driven by a variety of economic factors.

The District encompasses approximately 6.5 square miles in a highly urbanized area of largely unincorporated Clackamas County. The District comprises less than ten percent of Clackamas County’s population. It includes service to parts of the cities of Gladstone and Milwaukie, and Clackamas County Service District No. 1. Additionally, the City of Milwaukie and Clackamas County Service District No. 1 provides contract wastewater service to Oak Lodge Water Services District through intergovernmental agreements.

Water Reclamation Facility

The Oak Lodge Water Reclamation Facility (WRF) is a state-of-the-art facility located at 13750 SE Renton Ave. in Oak Grove, Oregon.  Construction of the WRF was completed in October of 2012, which increased the facility’s average dry weather capacity to 4.3 million gallons per day.  Significant construction improvements included a new influent pump station, headworks, clarifiers and microbiological processes.  A new UV disinfection system replaced the use of 1 ton chlorine cylinders and the supervisory control software significantly improved remote operations. 

Water Treatment Process

The WRF and 5 pump stations distributed across service area operate 24/7 to collect and treat wastewater to be returned it to the Willamette River. The facility cleans an average of 2.8 million gallons of wastewater per day, removing over 96% of pollutants.

Operations staff is committed to producing treated water that exceeds the parameters set by state and federal guidelines.

Biosolids

Annually, the WRF collects and treats approximately 900 dry tons of raw wastewater solids, which are treated to reduce total quantity to approximately 250 dry tons and to produce a product suitable for beneficial reuse. The raw solids treatment process results in Class B biosolids. The biosolids, meeting state requirements, are hoisted into enclosed trucks or dumpsters for transportation to agricultural farmland located in Clackamas and Umatilla counties.
