What is a sewer system overflow?
A sewer system overflow is a release of untreated sewage from a sanitary sewer into lakes and streams, often due to an accumulation of fats, oils and grease, blockages from baby wipes, facial wipes and sanitary products, system failure or construction activities.
What happens when the sewer overflows into a body of water, like a lake or a stream?
Untreated sewage can transmit diseases. When sewage enters the water, it can spread based on wind, water flow, rain events, volume of sewage and other factors. Sewage can stay in the water for days to weeks. Bellevue follows guidance provided by the Seattle-King County Public Health to determine the affected area and time frame of the issued advisory.
What should I do if I receive a notice to stay out of the water?
Humans and pets should stay out of the water. There is a risk that illnesses can be contracted with exposure to untreated sewage. The nose, mouth, eyes or open wounds are particularly vulnerable pathways. Please share the notice with your neighbors.
Can I still take my boat out in the lake when there has been a sewage release to the lake?
Yes, but based on Seattle-King County Public Health advisory, it's best to avoid the impacted area.
What if I was in the water before I received the notice to stay out of the water?
Take a cleansing shower immediately and monitor for any unusual symptoms. If you are concerned, seek advice from your healthcare provider.
How is the lake determined to be “safe” to swim?”
Seattle-King County Public Health (SKCPH) experts advise the City of Bellevue on the closure time frame and the impacted areas. They provide a map based on the volume of sewage and the time it was released.
How will I know it is safe to swim?
The closure dates will be listed on the door tag and on this page.
