Odor Notification Alert: July 20, 2020

 

We are taking final clarifier #6 out of service for inspection, cleaning and repair. The clarifier will be offline from July 20 through August 10 while we are cleaning, inspecting and performing repairs. While we take clarifier #6 out of service, their is a possible for odors to be produced. While we don’t anticipate these odors to be perceptible outside our campus, this is a possibility until the work 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 our campus boundaries.
