Air Treatment Facilities

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) at critical locations, where they will be most effective.


How the ATFs work

Odors are removed through a two-step natural treatment system with biotrickling filters. The system uses naturally occurring bacteria that "feed" on the odors. Further filtering occurs in vessels filled with carbon that is similar to carbon used in an aquarium filter.  No dangerous chemicals are used.

What will the Air Treatment Facility look like?

The ATFs are designed to fit into the neighborhoods in which they are located, both in their function and appearance. Each location is different in appearance.

The site features, space availability, and capacity requirements at each site will all play a role in determining the overall design concept for each facility.
