We are taking Digester #1 out of service to upgrade the system. This tank will be offline from March 7 through April 27 while we are emptying and cleaning the digester. While we take this tank out of service, it is possible for odors to be produced. While we don’t anticipate these odors to be perceptible outside the confines of the plant, this is a possibility until cleaning is complete. We know these odors can be unpleasant and we make every effort to reduce them.
Odors produced from the collection system and wastewater treatment plant are captured and treated through a variety of processes. Occasionally, maintenance activities will hinder our ability the capture and treat these odors, allowing them to be perceptible in surrounding neighborhoods. Environmental Services issues notification regarding these maintenance projects that may result in odors outside the plant’s boundaries.
Call 503-823-1700 to report odors (phone line is monitored 24/7).
Use the online Odor Monitor Report Form to report odors.
Request advance email notification of maintenance projects that may release odors from the plant.
