At approximately 8:00 am, Saturday December 8th, city staff was notified of a sewer main leak on the Butler Bridge force wastewater sewer mainline. It was confirmed the wastewater sewer main had a significant break in which untreated sewage was spilling into a defined containment area and was being controlled by staff until about 3:58 pm at which time the containment was no longer manageable.
Consequently untreated sewage began spilling into an adjacent stormwater catch basin, affecting the Depot Slough, a tributary to the Yaquina River. A city contractor was promptly notified and arrived on-site at approximately 4:00 pm to evaluate and begin the repair/replacement of the damaged mainline. At approximately 8:48 pm Saturday December 8th the replaced pipe section placed in the wastewater sewer main at which time the raw sewage spill halted.
This media notice is being made now as opposed December 10th to allow for the City to accurately report the estimated volume of the spillage. The amount of sewage that left the previously mentioned containment area is approximately 146,600 gallons. Appropriate fecal coliform tests were conducted indicating no negative results; the results of which are attached to this notification.
According to Oregon standards, Department of Environmental Quality (DEQ) and the Office of Emergency Services (OES) were promptly notified, along with other regulatory agencies. Appropriate signs and notices were made along the affected area. Measures were implemented at the discovery of the break to control flow towards a stormwater system.
Public Works staff acted responsibly, immediately implementing a safety plan. The Public Works Department would like to assure citizens their drinking water has not been contaminated.
