MEDINA, Wash. -- More than one million gallons of raw sewage backed up into Lake Washington over the weekend.
The sewer system in Medina was unable to handle all the rainfall from the storm, causing raw sewage to back up into peoples' homes and into the lake.
According to Annie Kolb-Nelson of King County Wastewater Treatment, about 1.6 million gallons of sewage spilled into Lake Washington over a period of 17 hours.
Wastewater Treatment took samples Monday to find out how much dangerous bacteria from human waste is now in the lake. It will take 24 hours for the test results to come back.
Robin Laskowski's spent Monday drying out her basement after it was swamped with sewage that backed up into her Carkeek Park home. It was one of four homes in that area that had sewage flow into it.
The same thing happened at Laskowski's home during a similar storm three years ago.
"These are things nobody should know how to do. You shouldn't know how to keep your environment free of sewage," she said.
The Laskowskis have a case pending against the City of Seattle regarding the last sewage flood they endured.
Tests for types of bacteria in Lake Washington are expected Tuesday. People are advised to stay out of the lake.
