Upcoming soil investigation work within and near Roegner Park

Starting as early as March 24, 2025 crews working for King County Wastewater Treatment Division will begin soil investigation in your neighborhood for the Lakeland Hills Pump Station Replacement Project. Crews will use a drill rig to drill four, 6-inch diameter holes to depths of up to 70 feet. After initial soil investigation, crews will install equipment to allow for ongoing groundwater monitoring. This work will provide detailed information about soil conditions for where the future pump station can be built. For safety reasons, please do not approach crews while they are working. 

Schedule and Dates

Work is expected to begin as early as March 24, 2025 and take approximately 3-4 weeks to complete.

What You Can Expect

  • Work hours are Monday through Friday from 8 a.m. to 5:30 p.m., with possible weekend work
  • 2 to 3 parking spaces will be occupied by contractors during work hours
  • Crews working on and around each location
  • A vehicle-mounted drill rig and support truck

About the Project

The Lakeland Hills Pump Station Replacement Project will replace the aging Lakeland Hills Pump Station and build a new facility in Auburn to upgrade sewer services in south King County. The pump station moves sewage from homes, schools, and businesses in the Auburn area to South Treatment Plant in Renton to be treated, eventually sending it off safely into the Puget Sound. Replacing the pump station will prevent sewage overflows and help serve the growing population of Auburn for many years.
