SMoke Testing Guide

Project Summary
Henry County Water Authority has contracted McKim & Creed to conduct Smoke Testing of your local sewer lines. The smoke testing will help identify areas where rainwater or groundwater enters the sanitary sewer system.Tests involve blowing non-toxic smoke into the sewer system to identify pipe damage, poor connections, and unwanted water infiltration. The smoke may be visible from vent stacks or ground holes. It is non-toxic, non-staining, white to gray in color, and poses no fire hazard.
The video below explains the process of Smoke Testing in further detail and highlights some common items to be aware of.

Should I evacuate the structure during testing?
The smoke is safe, non-toxic, non-staining, and harmless to you, children, pets, plants, food, and materials, and creates no fire hazard.
What should I do about my pets?

What should I do if smoke enters my home or business?

Smoke in your home/business may indicate deficiencies in plumbing. Please contact your plumber to further investigate.
Can the smoke testing activate the smoke alarm?
