Environmental Services is designing a project to rebuild the sewage pump station in the Hayden Island Safeway parking lot. The two existing pumps in the facility are aging and are too small to handle the amount of flow the pump station receives. Environmental Services will replace the existing small structure with a much larger one. The new Safeway Pump Station will house two new larger pumps, and there will be room to install a third pump as needed to accommodate future development. This project will help protect public health, property and the environment, and reduce the possibility of sewage releases into streets, homes and businesses.
Sewage flows downhill through pipes called gravity sewers in most of Portland’s collection system. Pump stations are located at low points in the system to pump wastewater uphill. This project will increase Safeway Pump Station capacity to manage the flow it receives.
The project includes repairs to manholes in the area and the main sewer line at N Jantzen Drive and Center Avenue. This will require some construction in the street, which will close a travel lane during construction hours, but flaggers will direct motorists and cyclists.
Environmental Services owns and operates nearly 100 sewage pump stations all around Portland, including five on Hayden Island. Two of them pump sewage to the Safeway Pump Station. The Safeway facility then pumps sewage to the Hayden Island Pump Station, which pumps it into a large gravity sewer that carries sewage to the treatment plant.
Construction will begin in early 2017and will take about 13 months to complete.
During construction, we will be sending out frequent email updates on schedules, traffic detours, delays, parking restrictions and other project news. I strongly encourage you to sign up for the project email update list by emailing your name to Rhetta.Drennan@portlandoregon.gov with “Safeway Pump Station” in the subject line.
Contact Rhetta Drennan with questions or concerns at 503-823-6006 or Rhetta.Drennan@portlandoregon.gov.
Based on the traffic control plan, the project will require about three (3) weeks of night work in N Jantzen Street at Safeway (see map above). Night work will occur from 9:00 p.m. to 7:00 a.m. in three phases during the course of the project: to repair the manhole in the street, trenching and laying new sewer pipe, and permanent paving restoration. The equipment used will include a pavement saw, track hoe, front-end loader, dump truck, bypass pumps, pavement roller, generators and lights.
Portland noise code allows construction from 7:00 a.m. to 6:00 p.m. Monday through Saturday. Work after 6:00 p.m. and before 7:00 a.m. and all hours on Sundays requires a noise permit from the Portland Noise Office. Because construction crews will work at night for up to three week, Environmental Services has applied for a noise permit.
You can submit comments to the Portland Noise Office by letter to Portland Noise Office, 1221 SW 4th Avenue Suite 110, Portland, OR 97204 or by email to email@example.com.

To prevent sewer backups and protect pipes, only flush human waste and toilet paper. Visit www.portlandoregon.gov/bes/WhatNotToFlush to see what happens when we flush products that don’t belong in the sewer. Wipes, disposable diapers and other products that claim to be flushable can block sewer pipes and cause sewage backups.
