Sewer Odor

Contact the City (913-971-9311) if your sewer produces an odor. Sewer gas and odors typically enter through a dry trap or floor drain:

  • Dry traps are in place to hold water so that sewer gasses do not enter the home or business.
  • In the event of sewer odor, pour water into all drains, particularly drains not often used, and then ventilate the area.
  • The property owner may need to hire a plumber to investigate and address sewer issue(s) if odor persists.

Sewer Backup

If sewage backs up into a basement, contact the City (913-971-9311) immediately to assess the situation.

  • City crews will respond to determine where the sewer line is blocked.
  • The City makes repairs if the blockage is located in the sewer main.
  • The property owner may need to hire a plumber to make repairs if the blockage is located in the service line, located from the main connection to the private property.

Wastewater Treatment Process

The City of Olathe is responsible for collecting, transporting and treating wastewater generated by homes, industry and businesses in Olathe.

The City operates two wastewater treatment plants and treats over one billion gallons of wastewater every year.

Millions of gallons of wastewater enter the treatment plants every day.  The wastewater travels through various stages of treatment to remove waste and eliminate disease-causing bacteria, and in turn protecting the environment for human and aquatic life.
