Residential Sanitary Sewer Overflow March 07, 2018

Last week the City received a citizen concern regarding a significant amount of water flooding their private property. City crews arrived on site and discovered that there was a deficiency in the sanitary sewer force main adjacent to this private residence. Crews immediately started cleaning up the spill and bypassed the force main by pumping the sewer into tanker trucks and dumping the sewage back into the system, downstream of the deficiency. The following day, construction crews mobilized, repairing the deficiency. 

When flow escapes or exits the sanitary sewer system at a non-permitted location, the Department of Environmental Quality (DEQ) identifies this as a Sanitary Sewer Overflow (SSO).  An SSO has the potential to affect public health and water quality.  All SSOs must be reported to DEQ and the Oregon Emergency Response System. 

With respect to this recent SSO, the City learned that the residence had been pumping the flooded area for three days into a storm drain inlet in front of their residence. The City would like to take this opportunity and inform the public that when abnormal flooding is occurring on your property, please contact the Public Works Department immediately. If you contact after or before normal business hours, you will be provided with emergency contact phone numbers.

Abnormal ponding can occur for several reasons. It is necessary to determine if flooding relates to a deficient underground utility as this could potentially be a health, safety, and water quality concern. 

Any questions can be directed to the City of Coos Bay Public Works Department at 541-269-8918.
