Smoke Testing on the Wastewater Collection System to begin September 6, 2011

This notice is archived content and this information may no longer be accurate.
On September 6th, the Wastewater Department will begin inspecting approximately 340,000 feet of wastewater pipelines throughout the city to identify sections of the wastewater collection system that allow stormwater to enter during heavy rainfall events. The testing will include the use of high capacity blowers placed over the manholes in the street to direct a specially manufactured, non-toxic smoke into the wastewater collection system. During the test, you may notice an odorlesss, white to gray colored smoke exiting the manholes as well as through the sewer vent stack(s) on your roof.

During the testing, a special, and non-toxic smoke is forced into the sewer lines in your neighborhood. This smoke leaves no residuals or stains and has no effect on plants or animals. Direct contact with the smoke may cause minor respiratory irritation in some people.

The smoke testing will be conducted by city sub-contractor, Altair Environmental Group. The crew members will wear photo identification badges and uniforms. The crew members will not request entry into your home, but will be available in the neighborhood to assist you if you have any questions about the process.
This testing cannot be conducted during certain weather conditions, so it can sometimes be delayed after the notice is placed.

To keep smoke from unnecessarily entering your structure, run water into all of your drains for one minute, especially those drains you use infrequently. Smoke should not enter your structure unless:
• Vents connected to your building's sewer pipe are inadequate, defective or improperly installed;
• Traps under sinks, tubs, basins, showers and other drains are dry, defective, improperly installed or missing; • Pipe, connections and seals of the wastewater drain system in and under your building are damaged, defective, have clean out plugs missing or are improperly installed.
If you do see or smell smoke in your structure, immediately report it to the Altair testing crew at (407) 948-2518. Do not be concerned if you see testing smoke coming from your rooftop sewer vents. This is normal.

A schedule will be placed on-line as soon as it becomes available. Please contact the Wastewater Department at 274-8393 if you have additional concerns or questions.
