Grotto Pump Station

Sign up for email updates

Environmental Service is constructing a new sewage pump station on NE Skidmore at 88th Avenue to replace a pump station the city built in 1998.The current pump station is too small to meet current demands. 

This project will remove the current structure and surrounding vegetation, and construct a pump station that will cover about twice the area. These improvements will protect public health, property and the environment, and reduce the possibility of sewage releases into streets, homes and businesses.

The new Grotto Pump Station will look very much like the Lents Pump Station pictured below. It will operate more quietly, and will use less power.

Lents Pump Station

Schedule - Construction will continue until spring 2017

Current Status:

  • Crews continue to work on erecting the building structure

What to Expect During Construction

  • Typical construction hours will be 7:00 a.m. to 6:00 p.m. Monday through Friday, with the same hours on Saturday as needed.
  • Parking will be prohibited in work zones during work hours.
  • Construction will create noise, vibration and dust, and will disrupt normal neighborhood activity.
  • The on-site city construction inspector should be able to help you with construction concerns during work hours. Inspectors typically wear a hard hat and a safety vest with “City of Portland” printed across the back.
  • Construction will not interrupt your sewer service and other utilities.
