DOVER – Smoke testing to help locate where sewer lines need repair will take place this week.
Workers will be in the Central Avenue, Chapel Street, Chestnut Street, Third Street, Second Street and First Street areas July 12 and 13.
The smoke is not a true smoke, according to information provided by the city, but instead is a mist containing a large percentage of atmospheric moisture that is highly visible even at low concentrations. It will not leave a stain and has no odor.
The smoke should not enter a home or business unless there is a defect in plumbing or dried up drain pipes. If there is an immobile individual who has respiratory problems in the testing area, crews need to know in advance. Call 570-7109 to notify them.
People with chronic asthma, emphysema or other respiratory problems should avoid direct exposure to the smoke.
If smoke enters a home or business, people should move to fresh air and seek medical attention if necessary, according to a safety data sheet.
People who notice smoke in their home or property should notify the crew working on their street or contact community services at 516-6450.
Crews will be placing door hanger cards on the doorknobs of affected properties. These cards say if smoke enters a home or business, it is a good indicator that sewer gases may also be entering that space.
Engineering consultants from Wright-Pierce in Portsmouth and Manchester will conduct the testing between 7 a.m. and 3 p.m. each day.
