Clearing the Air: The MSD clAIRity Program
MSD understands that dealing with the odors that naturally occur from wastewater treatment is challenging, and we’re hard at work for the neighborhoods most affected. We want to assure you that we are committed to mitigating these odors and making our communities the best possible places to live.
Through our MSD clAIRity Program, we are investing millions of dollars each year in odor-control measures. This means that we are putting money into making lasting changes to reduce the smells that come from the sewer and the wastewater treatment processes. In fact, we are currently in the process of replacing a number of untrapped catch basins found in parts of the community, including West Louisville.
Going forward, we will employ even more sophisticated tools to 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.
If you experience sewer odors, call 502.540.6000 or fill out this form to report the order. The sooner we hear from you, the better the chance of identifying the source and addressing the problem.
We appreciate your patience and understanding as we continue to work on your behalf to address this important issue.
