Sanitary Sewer Overflow, Jan. 4

City of Coos Bay release – Coos Bay is currently experiencing King Tides, storm surges, and intense rain events. This is causing increased water surface elevations within the bay. Due to these events, the outfall pipe that conveys treated and disinfected sewer effluent to the bay from the City of Coos Bay’s Wastewater Treatment Plant I (located at 680 Ivy Avenue) became hydraulically overloaded today at approximately 11:00 am, and it is currently ongoing (once the tide recedes it is anticipated that the overflow will stop), causing 275-300 gallons of sanitary sewer (treated and disinfected) to overflow from a manhole located adjacent to the Plant at the intersection of Koos Bay Boulevard and N. 6th Street. Since the treated and disinfected effluent did not discharge at the approved outfall location in the Bay, the Department of Environmental Quality (DEQ) requires the city to report this as an overflow. As a result, DEQ and the Oregon Emergency Response System (OERS) were notified of the incident. Any questions can be directed to the City of Coos Bay Public Works Department at 541-269-8918.
