Juanita Bay Pump Station replacement

The King County Wastewater Treatment Division replaced the Juanita Bay Pump Station, at 9290 Northeast Juanita Drive, to increase capacity and ensure safe and reliable operations. The previous station site was too small, so the new pump station was constructed across street (93rd Avenue Northeast). Construction began in fall 2005 and was completed early 2009.

Background

• The previous pump station was built in late 1960s
• Pump station serves 7,650 acres in north Kirkland and part of the Northshore Utility District
• Station pumps wastewater east through two pipes to the main conveyance pipe that follows the Burlington Northern and Santa Fe Railway to the South Treatment Plant in Renton

Need for project

• Replace aging pump station to ensure safe and reliable operations
• Address critical capacity needs by increasing the pumping capacity from 14.2 million gallons per day (mgd) to a peak capacity of 30.6 mgd
• Meet current design standards, including odor and noise control

Proposed work

• Replace the Juanita Bay Pump Station at 9290 Northeast Juanita Drive
• Build a new pump station across 93rd Avenue Northeast from the existing pump station
• Leave existing pump station in service while the new station is built
• Design the building and landscaping to fit the neighborhood.
• Choose equipment to enhance safe system operation and reduce odors and noise
