The City of Trenton is warning residents of issues surrounding an upcoming sanitary sewer system testing needed to locate existing and potential sources of infiltration/inflow.

The city has hired TREKK Design Group to document flow measurement, manhole inspections and smoke testing activities.

The city says most of the project will take place with little to no impact on customer.  However, when smoke testing is done it said customers could see smoke coming from the vent stacks on houses or holes in the ground but that it is non-toxic, harmless and has no order nor does it create a fire hazard.

“The smoke will not enter your house if the plumbing is installed properly and drain traps are not dry,” the city said in a news release. “If smoke does enter your residence or business it is recommended that you consult your plumber.”

It said if the smoke can enter there is also a potential for dangerous sewer gasses to enter.

48 hours prior to smoke testing door notifications will be distributed at each home in the area being tested.
