Beaches at two Everett parks — Howarth and Pigeon Creek — remained closed Saturday after sewer overflows caused by heavy rains.
The city of Everett earlier closed five beaches, but reopened three of them Saturday after tests showed that water quality had returned to normal. The reopened beaches are at Langus Park, Rotary Park and Jetty Island.
City officials said heavy rainfall on Thursday led to sewer overflows into the Snohomish River and Port Gardner Bay. A sewer lift station also overflowed near Pigeon Creek for about 20 minutes, they said.
Under normal conditions, the sewer system carries rainwater runoff plus sewage and industrial wastewater to the Everett Water Pollution Control Facility for treatment. During heavy rainfall or snowmelt, the city said, the amount of wastewater exceeds the sewer system’s capacity, and overflows occur.
