City Sewers


About odors

Odors usually remain inside of the sewers, but when a pipe runs quite full and/or the sewer changes its elevation underground enough to stir up the wastewater, smells build up to the point where they can escape to the outside air. Odors can escape sewers through pick holes in maintenance hole covers, through vents, and other very small openings in the pipeline and connection points.

The Best Solution

The City’s Odor Control Program

One of the Department of Public Works’ highest priorities is treating objectionable sewers odors and preventing those odors from entering nearby neighborhoods. The ultimate means for accomplishing this goal is the installation of permanent Air Treatment Facilities (ATFs), where they will be most effective.
