Odors are usually not perceptible beyond the boundaries of the Columbia Boulevard Wastewater Treatment Plant. Occasionally, plant maintenance projects will release odors that may be perceptible in neighborhoods surrounding the plant. Environmental Services issues advance notices of maintenance projects that may result in odors outside the plant’s boundaries.
We know these odors can be unpleasant and we make every effort to reduce them. Odor control is important to us at the plant, and we appreciate you taking the time to let us know of odors in your area.
