City of Coos Bay release, Jan. 12, 2021 – Coos Bay is currently experiencing extremely high 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 fully treated and disinfected sewer effluent to the bay from the City of Coos Bay’s Wastewater Treatment Plant 1 (located at 680 Ivy Avenue) became hydraulically overloaded today between 11:15 am and 1:10 pm. It is estimated that approximately 24,750 gallons of treated and disinfected sanitary sewer overflowed from the outfall 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, the Oregon Emergency Response System (OERS), and the Department of Agriculture were notified of the incident. Any questions can be directed to the City of Coos Bay Public Works Department at 541-269-8918.
