Odors are usually not perceptible beyond the boundaries of the Columbia Boulevard Wastewater Treatment Plant .
Occasionally, plant maintenance projects on odor control equipment 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.
December 3rd to the 17th we will be takeng digester #6 out of service as part of an ongoing project to upgrade the mixing capabilities of the digesters. Better mixing capabilities will promote a more productive digestion process and prevent mechanical equipment from experiencing premature wear and tear.
December 4th to the 5th we will be taking aeration basin #7 out of service to repair a break in the air line. This repair will ensure proper distribution of air into the biological treatment process and allow the air distribution system to run more efficiently.
