By watching to see where smoke escapes, crews can identify problem areas in the pipes for further sanitary sewer investigation techniques. Smoke may be seen coming from manhole covers, storm inlets, or holes in the ground. On occasion, smoke may be seen coming from building foundations or roof vent stacks. However, the smoke should not enter your home or business unless you have defective plumbing or dried-up drain traps. If you have any seldom used drains, pouring water into the drain to fill the trap will help prevent sewer gases or odors and smoke from entering your home or business.
Your neighborhood should receive flyers on your doors alerting you to the day it’ll be done.
