A: First, try to determine where the odor is coming from (inside the house or outside in the street).

If an odor is coming from inside the home, there may be a problem with the internal plumbing system. Check your internal system first or call a plumbing company in the yellow pages of the phone book under "Plumbing Drains & Sewer Cleaning" or "Sewer Contractors."

If the problem exists outdoors, call the RVSD at 415.259.2949 for service.
