PRINCETON — Sewer smoke testing for the city of Princeton will take place the week of May 12.

As part of efforts to reduce clear-water entry into the sanitary sewer system, testing of the sewers will be conducted in the following areas: North Euclid Avenue between Hudson Street and Warren Street; Hudson Street; Franklin Street; Jacqualine Lane; Fox Creek; and Linwood Drive.

During the examination, a dense grayish/white smoke will be blown through the sanitary sewers from a manhole. Smoke will then appear from any roof drains, catch basins or house vent stacks connected to the system. In addition, the smoke may appear from cracks in the pavement above the sewer, from lawns or around homes which have foundation drains connected to the sewer. The appearance of smoke from house vent stacks is normal and does not indicate a defect in the plumbing.

Smoke may also appear in basements by means of unused floor drains, disconnected or faulty plumbing fixtures, or any direct opening to the house lateral. To reduce this possibility, pour water down all floor drains, sinks or other plumbing fixtures. This water will fill the plumbing trap and prevent the entry of smoke.

The smoke used in this program has been analyzed by a team of experts in the field of industrial hygiene, toxicology and medicine and has been proven harmless. Although harmless, the smoke may irritate nasal passages but irritation should disappear quickly after exposure has ended. Those persons suffering from heart or lung diseases, such as emphysema, should attempt to avoid exposure as they would any other potential airborne irritant.

Testing will not take place in inclement weather. For more information, contact the city of Princeton at 815-879-3961 or Visu-Sewer Inc. at 800-876-8478.
