HARRISONBURG -- Harrisonburg Public Utilities is conducting tests on portions of the sanitary sewer system this week through the end of June. People nearby may see smoke in some man holes, but should not be alarmed.
The testing will take place on the east side of Interstate 81 from Ramblewood Road to Port Republic Road.
Public utilities will release a non-toxic and non-staining smoke to find any breaks or leaks in the sewer line.
James Fultz is an engineer with public utilities and he said for people who live in the area, there are a few to do.
"Pour water into floor drains and utility sinks. If you do see smoke, if they have any respiratory or cardiovascular problems, we would ask that they would just leave the premise, get out of the premise and call a plumber until they can have it repaired," said Fultz.
Fultz said the most common problem is covers people mow over in their yard.
