Barnstable to Conduct Smoke Testing and Voluntary Building Inspections

July 12th from 8 a.m. to 5 p.m.

From the Town of Barnstable:

In order to improve sewer service, on behalf of the Town of Barnstable, Weston & Sampson will be conducting smoke testing on portions of the sanitary sewer system within The Villages at Marston Mills (624 Osterville-West Barnstable Road) from 8:00 a.m. to 5:00 p.m., on July 12, 2018, weather pending.  In addition, voluntary building inspections will be conducted on the same day.  These inspections are being conducted as part of the Town’s on-going sewer Infiltration and Inflow (I/I) Investigation project. 

The purpose of smoke testing is to locate sources of rainwater entering the sanitary sewer. During the test, white smoke is introduced to the sanitary sewer system via a smoke-generating machine.  During this procedure, white smoke will be venting from holes in manhole covers located in the street and from plumbing vent pipes located on or near your roof surface. THIS IS NORMAL AND SHOULD NOT CAUSE ALARM.

Smoke should not enter your premises unless there is either a dry trap in an unused fixture or a plumbing defect.  You may wish to pour two gallons of water down your basement floor drain or unused plumbing fixture to ensure that the drain trap will be effective.

Should smoke be detected within your building, do not be alarmed.  The smoke is NON-TOXIC, NON-STAINING, and dissipates quickly through open windows.  IF YOU HAVE A LUNG AILMENT or RESPIRATORY CONDITION SUCH AS ASTHMA OR EMPHYSEMA, STAY AWAY FROM THE SMOKE.  Any smoke within a building should be immediately reported to the persons conducting the tests.

Voluntary building inspections will be conducted by the town’s wastewater consultant, Weston & Sampson, in a “door-to-door” fashion.  The inspections will last about 10-15 minutes and will be performed by a two-person team who will carry proper identification.  The team will evaluate the basement or equivalent lowest level of each building to determine if any of the common sources of inflow such as sump pumps, floor drains, etc. are connected to the sewer system.  The exterior of each building will also be checked for potential inflow sources. 

The Town of Barnstable is asking every homeowner within the study area to help by taking part in the Voluntary Building Inspection Program. 

Weston & Sampson company vehicles are gray or black with the company name on the sides and smoke testing personnel will have current Weston & Sampson ID card. 

Any questions should be directed to Weston & Sampson at (774) 251-3150. Please leave a message including your name, address, and telephone number and you will be responded to promptly.
