Clearing the Air: The MSD clAIRity Program
The MSD clAIRity Program is our proactive odor control initiative designed to reduce sewer and wastewater treatment odors now and into the future. Every year, MSD invests millions of dollars in odor control measures including chemical, biological and thermal oxidation technologies.
Going forward, we will employ even more sophisticated tools to eventually achieve our goal of “no-nuisance” conditions across all of our Water Quality Treatment Centers. These tools include scientific identification and quantification of odors and partnering with research firms to evaluate each of our Water Quality Treatment Centers.
Our multi-year Odor Control Master Plan includes strategic investments to make improvements to the system that reduce odors caused by sewer and wastewater treatment processes.
With Your Help, We Can Reduce Odors
Let’s face it: Sewer and wastewater treatment is an “odorous” endeavor; it just comes with the territory. However, while MSD can’t stop all the smells that naturally occur when sewage and other materials decompose, we can help manage them – with your partnership.
Common Sources of Odors
Water Quality Treatment Centers
Creeks, Streams or Drainage Ditch
