Wastewater treatment facilities

To understand where WES stands today, it is helpful to know how far we’ve come regarding wastewater treatment services.

It’s hard to imagine not being able to flush a toilet to carry wastewater away from our homes or businesses and yet 60% of the world – 4.5 billion people – don’t have a toilet at home.

The Tri-City Plant was constructed as part of a major program to eliminate raw sewage overflows to the Willamette and Clackamas Rivers and in response to a building moratorium. The Tri-City Plant replaced three obsolete plants in West Linn and Oregon City. The Tri-City plant was the first municipal plant in Oregon designed to treat ammonia biologically.

Kellogg Plant

Kellogg Water Resource Recovery Facility (serves the North Clackamas Urban area, and the cities of Happy Valley, Johnson City and Milwaukie)
Startup: August 1974

The Kellogg facility was constructed to provide service to the North Clackamas Area which was being served by septic systems. Building in many areas of the district was suppressed until sewer service was available because the septic systems could not be permitted under then "new" state septic system regulations.
