Sanitary Sewer Smoke Testing Around Wadams Farm Development Today

The District of Sooke will conduct smoke testing of the sanitary sewer system around the Wadams Farm development at approximately 10 a.m. today. While testing is mostly within the Wadams Farm Development, effects may occur on Church Road and Wadams Way as well.

Smoke testing is a standard inspection method used to identify cracks, leaks, faulty connections and other openings that may allow rainwater to enter the sanitary sewer system. The testing will help the District assess the condition of the sewer network and identify potential repairs.

What residents may see

Crews will introduce dense, simulated smoke into the sanitary sewer system. Smoke may be visible from:

• Rooftop plumbing vents
• Manhole covers and sewer cleanouts
• Cracked or damaged pipes
• Faulty plumbing connections
• Improperly connected roof, foundation or area drains

Smoke coming from a rooftop vent or manhole does not necessarily indicate a problem. These are normal openings in the sewer system. Smoke appearing from the ground or entering a building may identify a defect requiring further investigation.

Why smoke testing is important

The sanitary sewer system is designed to carry wastewater to the treatment plant. When rainwater enters through cracks, damaged infrastructure or improper connections, it uses capacity intended for wastewater.

During heavy or prolonged rainfall, this additional water can overwhelm the system and increase the risk of sewer backups and overflows. Identifying these defects helps protect the reliability of the sanitary sewer system, inform future maintenance and safeguard public health and the environment.

Is the smoke safe?

The simulated smoke is non-toxic, non-staining and safe for people, plants and animals. It dissipates quickly and does not leave a residue. Residents should not be alarmed if they see smoke outdoors during the testing.

Should smoke enter a building?

Smoke should not enter a building when plumbing is properly installed and drain traps contain water. Before approximately 10 a.m., residents and businesses in the area are encouraged to:

• Run water for 30 to 60 seconds in seldom-used sinks, tubs and showers
• Pour approximately four litres of water into infrequently used floor drains, garage sinks or other drains
• Check that sewer cleanout covers are securely in place

This fills the U-shaped plumbing trap, or “P-trap,” creating a seal that prevents smoke and sewer gases from entering the building.

If smoke enters your building

Pour approximately four litres of water into the affected drain and open a door or window to ventilate the area.

If the smoke is not entering through a dry drain trap, contact a licensed plumber. An opening that allows testing smoke to enter may also allow sewer gases into the building and should be investigated.
