Around 5 p.m., crews responded to a sewage release flowing from one catch basin to another nearby basin. Crews vactored the basins and stopped the release. The likely cause was determined to be tree roots clogging the sewer.
This advisory will be updated once additional information becomes available.
Environmental Services reminds the public that most sewage releases are preventable. The most common causes of sewage overflows are pipes clogged with household debris, such as cooking grease that is sent down kitchen drains or wet wipes that are flushed. Both belong in the trash, not down the drain. Tree roots are another common cause. Environmental Services advises the public to follow these tips to prevent clogs and overflows in homes and businesses and to prevent sewage releases:
If you experience or see a sewer overflow, contact the City's hotline at any hour of the day at 503-823-1700.
