Tri-City Service District Clackamas County

Did you Know?

Clackamas County Water Environment Services (WES) manages the daily operations of the Tri-City District and their Water Pollution Control Plant. The plant, located in Oregon City, treats wastewater for the Tri-City Service District, including the cities of Gladstone, Oregon City and West Linn.

The Tri-City Water Pollution Control Plant has a 20,000 sq ft green roof providing habitat for hidden ecosystem - The Dry Season Green Roof Biodiversity Study by Dimitri Meierhofer, a Swiss scientist from UG Lab and the Green Roof Competence Centre of the Zurich University of Applied Sciences (ZHAW), is studying invertebrates that live within rooftop ecosystems in Oregon, California and Mexico. Click here for more information on the study

Innovative Approach - An industry publication features our Tri-City plant as a "model of sustainability" in a recent article.  The Tri-City plant uses innovative Membrane Bioreactor treatment technology to save space, reduce odor, and generate much cleaner treated water than conventional approaches.  Click here to read the article.

Keep wipes out of the pipes 
Did you know that flushing items such as cleaning and baby wipes can cause damage to our sewer system? Many things routinely flushed down the toilet or washed down the drain, including those sold as “flushable” can cause expensive maintenance problems and sewer back-ups in your home, the public sewer system and in the environment. The following are examples of what should not be flushed or washed down the drain:

  • Baby and cleaning wipes
  • Paper towels
  • Cotton balls, swabs and pads
  • Facial wipes and tissue
  • Feminine Products including the applicators
  • Unused medications
  • Chemicals
  • Fats, Oils and Grease (FOG)

Thank you for protecting public health and the environment in Clackamas County.
