City crews perform routine cleaning operations on the sanitary sewers throughout the year. This is done to remove tree roots and debris from the sanitary sewer system. This process improves sewer performance and reduce the chance of sewer backups and other related problems.
The cleaning process causes a vacuum in the sewer, which will not affect most homes. However, some homes may experience problems with inadequate or partially blocked drain vents. The vacuum may cause P-traps (the s-shaped bend in the pipe under sinks and drains) to be sucked dry.
Residents who notice a sewer smell are advised to run a small amount of water in their drains to refill these traps. Residents may also notice a bubbling or gurgling noise during cleaning operations. Most of the City’s sanitary sewer system is cleaned on a three-year cycle. Some locations in the City are cleaned as often as every three months, depending on conditions in the area.
