Clackamas Water Environment Services will conduct leak detection tests on the pipes of the sanitary sewer system throughout the City later this month.  Smoke tests are performed by pumping a special non-toxic, non-staining smoke into the sewer lines to detect leaks in our pipes. If there is a crack or break anywhere in the pipeline, the smoke will rise to the surface and the crew can visually see the location where repairs are needed. If damaged, water from rain or naturally occurring groundwater can seep into pipes that are broken or cracked, adding to the flow of water going to the wastewater treatment facility or exceeding the capacity of the system causing raw sewage to overflow to the Clackamas River. More flow means increased costs. Keeping this water out of our pipes saves money and helps keep our river water clean.

If you have any questions about the smoke testing program, please contact:
