In 2023, Louisville, KY experienced significant wastewater odor issues that quickly became a highly visible and political concern within an underserved community. In response, the Louisville & Jefferson County Metropolitan Sewer District (Louisville MSD) shifted from a largely reactive odor response model to a proactive, data-driven strategy centered on real-time hydrogen sulfide (H₂S) monitoring, community engagement, and targeted mitigation. The Louisville Metropolitan Sewer District (Louisville MSD) operates a large, combined sewer system that includes five Water Quality Treatment Centers, 304 pump stations, 16 sewer storage basins, nearly 2,700 miles of gravity sewer mains, and roughly 80,000 manholes. Managing H₂S odors and corrosion in a large system requires continuous situational awareness that periodic sampling alone cannot provide. Beginning in June 2025, Louisville MSD launched a pilot program deploying real-time H₂S monitors at strategic locations within the collection system. By September 2025, the program expanded to full-scale operation. Currently, two H₂S monitors are integrated with seven applications that combine Doppler radar rainfall data and local rain gauges, providing a comprehensive view of how storm events, flows, and operational activities impact odor formation. One monitor tracks downstream stormwater and wet-weather releases to treatment plants, enabling proactive mitigation before odor spikes occur. A second monitor is installed at a point where three large-diameter sewers converge, allowing early detection of turbulence-related odor. Additional monitoring locations, including at 13th & Rowan and downstream of major industrial contributors, help distinguish contributing sources from downstream impacts. Continuous monitoring has transformed odor management by identifying odor spikes in real time, evaluating the effectiveness of chemical dosing, reducing manual inspections, predicting maintenance needs, and minimizing corrosion, overflow risks, and compliance concerns. Trend data now show rising H₂S levels hours before community residents become aware. That early notice allows staff to intervene before reports are made by notifying residents early and encouraging them to be prepared. Paired with the technology, Louisville MSD launched the Let’s Talk Odor portal on its website in 2025 for community engagement and education about odor management. A big focus is the clAIRity initiative, five public meetings annually to share data, explain mitigation efforts, and gather resident feedback. The Let’s Talk website portal also has information about odor mitigation, including an odor reports tracker, odor mitigation projects, and odor response and cleaning standards. In one year, odor reports declined 29%, 1,712 in 2024 to 1,221 in 2025. Based on the results, Louisville MSD is planning to expand its real-time monitoring program to further improve environmental performance and community relations. Odor management efforts by MSD highlights how data-driven technology, paired with intentional public outreach, can improve operations while addressing long-standing community concerns. What was once a reactive response to odor reports has evolved into a proactive, precision-based program. Early results show measurable reductions in odor complaints, more informed operational decision-making, and improved trust between Louisville MSD and the communities it serves.
