Public Works will smoke test in the Churchill, Far West and Southwest Hills neighborhoods in July and August of 2017. A notice will be placed on your door one to two days before smoke testing work is scheduled to begin in your area.

If someone in your family has a lung ailment (such as emphysema) and should not be exposed to any type of smoke, please call Public Works Maintenance at 541-682-4800.

Sewer Inspection Program

       
The Public Works Department periodically investigates sanitary sewer lines throughout the city. The inspections help pinpoint defects and improper connections that cause stormwater and groundwater to infiltrate the wastewater collection system. The increase in water can overload the region's wastewater collection and treatment facility.

Staff test for potential problem areas by utilizing closed circuit television, dyed water and isolated smoke testing.

Smoke Test Safety


Smoke testing is endorsed by the U.S. Environmental Protection Agency. The smoke, called Liquismoke, is non-toxic and does not harm plants or animals. The smoke dissipates quickly and does not leave residues or stains. 

‚ÄčSmoke Testing Process

 
Staff use machinery to blow smoke into the sewer lines. During the tests, a non-toxic white smoke will be released into the public wastewater system. The inspection of where smoke emerges helps crews assess the condition of the system and determine specific problems regarding private building sewer connections as well as public sewer in streets and easements.

Defects


If smoke testing reveals a defect in the public portion of the wastewater collection system, the defect is corrected as soon as possible. If extensive defects are found, capital rehabilitation projects are planned, funded and completed to correct the problem.

Prohibited Connections


If smoke testing identifies a stormwater connection prohibited in the City code, such as a roof drain connected to the sanitary sewer, the property owner is notified and is required to correct the problem.

Private Sewer Defects


If the testing indicates a defect in the private portion of the sewer, which is usually in the line that connects the building to the public sewer, the owner is notified of potential problems with the sewer and repair or replacement of the defective line is recommended. 

‚ÄčImportant Steps for Homeowners


To minimize the chances of smoke entering your home, we recommend residents pour water into seldom used plumbing fixture drains (such as sinks, laundry tubs, washing machine drains, showers and bathtubs) and any floor drains within the house, basement or garage.
