Advisory: Sewage release along NE Marine Drive flows into ditch, river not affected

Sanitary Sewage Release Advisory

(this is not a combined sewer overflow [CSO] advisory)

(October 11, 2017) – A malfunctioning valve on an underground pipe led to a sewage release this morning along the side of NE Marine Drive at 112th Avenue near the I-205 overpass.

The sewage flowed through a storm drain and to a ditch. Crews cleaned up the flow along the road and the portion in the ditch soaked into the ground. The sewage did not reach the Columbia River.

The release occurred west of the I-205 bike path and that path is not affected.

Crews determined that about 18,750 gallons was released during a 75-minute period. Crews repaired the valve, which was housed in an underground vault, stopping the release at 8:45 a.m.

The public is advised to obey warning signs posted along Marine Drive.

The City of Portland treats an average of 70 million gallons of wastewater each day. Over one-third of Portland’s more than 2,500 miles of sewer pipes are over 80 years old.
