(Portland, OR) -- Raw sewage flowed into the basements of three homes in Northeast Portland Tuesday night. The Portland Bureau of Environmental Services says the sewage initially flowed into the intersection of Northeast Broadway and Weidler near 86th Avenue. Some sewage got into the basements of three homes. The spill was caused by a failed sensor that was supposed to activate a pump. The sewage release was stopped by 11 p.m. City crews cleaned the street and gave residents advice on cleaning up the mess. They can also file a claim against the city for the costs.
