36th Avenue Pump Station Project

36th Avenue Pump Station

The 36th Avenue Pump Station is located near the NW 36th Avenue Bridge where it crosses Salmon Creek. The station is the red brick building on the opposite side of the road from the Salmon Creek Greenway public trailhead access.

36th Avenue Pump Station Pumps

This project will replace three 200-horsepower primary sewage pumps and motors.

Project Overview

This project will replace three 200-horsepower sewage pumps and motors at the pump station along with associated piping. The existing equipment was installed over 20 years ago and requires replacement in order to maintain reliable and effective transmission of wastewater to the Salmon Creek Treatment Plant.

While construction activities will be confined to the pump station property itself, the project will require construction crews and equipment to access the site for several months. Residents who live on NW Creekside Drive, which is immediately adjacent to the pump station, will be notified prior to construction taking place.


Costs for the 36th Avenue Pump Station are covered in the Capital Plan. In total, the project is expected to cost $1,400,000.


Construction is slated to begin in the spring of 2018 and be completed by late fall 2018. When you see the activity at this location next year, you will know that we are proactively replacing aging equipment to keep our sewer system operating reliably.
