Try to locate the source of the odor. Odors could come from local sewers or King County’s system. Many King County sewer manholes have "METRO" on the lid.
Report the odor as soon as possible. Give the location and the time it occurred. This information will help locate the odor and investigation.
For odors occurring in homes, businesses and local sewer pipes and storm drains, call your local sewer agency. The phone number to your local agency can be found in your sewer bill.
For odors that can't be specifically located, call the closest King County treatment plant's Odor Control Hotline for assistance.
King County is committed to odor control. However, we cannot guarantee that there will be no odors in our existing system. Occasionally, equipment will need to be shut down for clean up, preventive maintenance or repairs. Please call the odor hotline if you experience odors, and we will do everything we can to restore our high level of odor control.
