If the Sewer Odor is Indoors:
What you can do before calling USD:
Check your traps. A dry trap is the most common cause of sewer odors indoors. Traps are typically visible under sinks, and are similar to the drawings below. Every shower, tub, floor drain and toilet has a trap, too. Water resting at the bottom of this "U" shaped device creates a constant seal between the fixture and the sanitary sewer system.

Read more about maintaining your traps and vents.

If you have checked your traps and are still concerned about an odor in your building, call USD at the numbers above. We will dispatch personnel to investigate the odor.
