Don't be alarmed next week if while driving through Dedham, you spot white smoke seeping up from the ground. It's supposed to be there.
The town along with Weston & Sampson, an environmental and infrastructure engineering consulting firm, will be conducting “smoke testing” throughout the sewer system, from Monday through Nov. 23.
During the testing, white smoke is sent into the town’s sewer system via a smoke machine. The smoke allows contractors to see where rainwater may be entering into sanitary sewer pipes.
According to a news release, officials hope this information will allow Dedham to remove any excess water flow and reduce the amount of wastewater it sends to the Massachusetts Water Resources Authority.
Several areas around town will be tested, and residents will most likely see white smoke venting from holes in manhole covers and from plumbing vent pipes, which is normal and part of the procedure.
When the smoke test comes to a particular neighborhood, residents will receive a yellow notice informing them of the dates and times of the test. Tests will be done within 72 hours of sending out notices.
The smoke is non-toxic and non-staining; however, some people with lung issues such as asthma or emphysema might be irritated by it. Residents with related health conditions who have received notices about smoke test should contact Weston & Sampson at 781-751-9067.
The following locations will be test on the first day, Monday:
