How to Identify Odors Outside Your Home or Business

Sewer odor is caused by hydrogen sulfide, which forms when sewage and other materials decompose. Hot, dry weather, along with other factors, contribute to sewer odors. 

Common Sources of Odors

Water Quality Treatment Centers

Pump Stations

Catch Basins

Creeks, Streams or Drainage Ditch

The majority of outdoor catch basins feature water traps, which uses water to stop sewer gases from escaping into the air. However, if you smell a sewer odor near a catch basin, Water Quality Treatment Center or a nearby body of water, call (502) 540-6000 or fill out this form, and we will begin working to address your issue immediately.
