Notice of Smoke-Testing To Be Conducted in Catchment No.6

Date
-

Please be advised that Superior City Services on behalf of the City of Langley will be conducting smoke-testing in Catchment No. 6. 

To help explain what this means to you, we have prepared this list of Frequently Asked Questions:

1. What is smoke-testing?
Smoke-testing is a standard method of confirming and identifying connections to the sanitary sewer system and identifying improper connections and defects.

2. How does it work?
Smoke-testing consists of forcing a non-toxic fog, similar to that used in theatrical productions, into sewer manholes. The field crews then monitor where the smoke escapes. If smoke permeates up through the ground, or exits via gutters or downspouts, then a problem is indicated and will need to be corrected.

3. Is the smoke dangerous in any way? 
No. The “smoke” is specifically manufactured for this purpose. It leaves no residuals or stains on clothing, draperies or furniture and is not harmful to humans, plants, or animals. Some people may find the smoke irritating to nasal passages. Individuals with respiratory concerns may contact the City for specific testing times.

4. Will smoke enter my home during the testing?
Probably not. Smoke should not enter your building unless you have defective, damaged, or improper plumbing OR if you have infrequently used drains that have dried out over time.

5. Is there anything I should do in advance of the testing?
Yes. To avoid smoke entering your building unnecessarily, we advise you to run water into all drains, including floor drains located near hot water tanks or in basements, for at least 30 seconds. This will fill the P-trap with water, which will create a barrier and prevent the smoke from entering the building via your drains. *Please do this upon receipt of this notice, as the water in the trap will remain effective for several months.* SMOKE-TESTING NOTICE cont’d.

6. What should I do if smoke enters my house?
The smoke should dissipate in about 20 minutes. As an added precaution, you may leave some windows open for ventilation purposes during the testing. If smoke appears in your home, it is likely that harmful sewer gases have been entering the building for some time. Please note the location of the leak and contact the field crews at 1.604.841.5468. While the City of Langley will render all help possible, the correction of any defects in pipes and sewers on private property is the responsibility of the property owner. *If there is smoke in your home and you are not sure if it is due to these tests, please call 911.* To prevent false alarms, the Langley Volunteer Regional District Fire Department has been notified of this smoke-testing work.

7. Is there anything else I should know?
It may be necessary for field crews to enter your property during the testing, but there is no need for them to enter your home, unless you have detected smoke and want them to identify the source of the leak. You do not need to be at home when the testing is underway. Smoke-testing is an important part of keeping the Town’s sanitary system running efficiently and in an environmentally friendly manner. We appreciate your understanding and patience as we conduct this maintenance work.
