LO responds to sewage leak near Springbrook Creek
A broken sewer line near the intersection of Kruse Way and Boones Ferry Road caused an unknown amount of sewage to leak into nearby Springbrook Creek and subsequently Oswego Lake.
The leak was discovered by a City employee around 2:30 p.m. Monday, July 8. The City responded immediately following their overflow response plan and found the leak was caused by a break in a sewer line.
According to Wastewater Superintendent Phil Lawrence , the break in the line was caused by a boring contractor that hit a line they were unaware of.
Crews were able to stop the leak by 5:30 p.m. and the line was repaired around 10 p.m., but the amount and duration of sewage release was unknown.
The City notified the Oregon Department of Environmental Quality soon after the leak was discovered and began coordination remediation efforts along with the activation of the state's emergency response system.
Upon further investigation, public works crews found that some of the sewer/wastewater that had been released entered a storm drain that flowed into Springbrook Creek, and water samples were taken at several points along the creek to help determine the extent of the release.
According to Public Works Director and Deputy City Manager Anthony Hooper, when the spill was determined to be larger in nature, LO Public Works notified residents in the immediate vicinity of the overflow spill area as well as the Lake Oswego Corporation.
A notification was sent to neighbors using the social media app Nextdoor, as well as a notice sent out by the Lake Oswego Corporation to those with access to Oswego Lake. In the notification, City officials advised the public to avoid any contact with water in Springbrook Creek and downstream water at Oswego Lake at the mouth of Springbrook Creek (at Springbrook easement) until further notice. Signs were also posted at strategic locations along Springbrook Creek.
"The City is very concerned about the health and safety of those in our community and will continue to monitor and test the water in the impacted area," Hooper said in an email Wednesday morning. "Once the tests come back clear, the public will be notified that it is once again safe to be in contact with the water. The City is continuing to investigate the cause of the sewer line break and will take steps to reduce these types of releases in the future."
Ward told The Review Wednesday that Lake Corp staff is monitoring the situation alongside LO Public Works. The Lake Corp sent out an email notification around 1 p.m. Monday notifying shareholders of the spill. They tested water in Oswego Lake near the Springbrook Creek easement Wednesday and are awaiting the results of those tests, but for now they're telling shareholders to avoid contact with the water in that area.
According to Ward, the Lake Corp will be continuing to notify lake shareholders on the situation as updates are made available.
Monday's leak was the second in the last two months; in June, the City responded to a spill at George Rogers Park.
