COLUMBIA — Sewer utility workers will be performing smoke tests on a sanitary sewer main downtown on Tuesday morning.
The Columbia Public Works Department is running the routine maintenance test to detect any leakage in the sewer lines, , the department's public information specialist, Jill Stedem, said. Stedem said a business in the area reported smelling sewer odors from time to time.
A team of two to four workers will blow a nontoxic, odorless white smoke into a manhole from 7 to 8 a.m. in the alley between Broadway and Walnut Street from Eighth Street to Ninth Street. Smoke may be released from vent stacks on the roofs of adjacent buildings or manholes, Stedem said.
"People may see smoke coming through various areas, and we wanted to make sure people were aware that it's not a fire or anything harmful," Stedem said.
