Wastewater Facilities

Clean water is the biggest lifesaver in human history.

Thanks to advances in producing clean water over the last 200 years, life expectancy in the United States has more than doubled to 78.8 years. Most people take drinking water coming out of taps in our homes for granted. It’s also hard to imagine not being able to flush a toilet to carry wastewater away. The toilets and sewer systems we use today save millions of lives by preventing the spread of deadly diseases that come from dirty water.

At Clackamas Water Environment Services, we provide wastewater treatment services for more than 190,000 customers. 

Each year, our treatment facilities clean more than seven billion gallons of wastewater.  In the process, we convert materials that have long been considered “waste” into energy and natural fertilizer. We operate and maintain five resource recovery facilities, 23 pumping stations and more than 360 miles of pipes.
