Wondering what the new facility will look like? Here is our current rendering :
King County began the process to obtain construction permits. Permitting may take longer than originally anticipated. A new completion date will be updated as soon as we know more.
What is the Loop Vehicle Maintenance Facility Project?
King County Wastewater Treatment Division (WTD) is designing a new vehicle maintenance and staging facility for transporting Loop biosolids. The new facility will be located in North Bend (exit 34 off I-90) on County-owned land.
Why is King County building this facility?
- The current vehicle facility is located in south Seattle, on a space leased from the King County Airport. The lease on this land is now ending without the option to renew, requiring WTD to relocate the facility.
- Helps meet new federal regulations that limit the time a driver can be on the road.
- This facility reduces driving time and improves safety for every traveler on our highways and roads.
What are Loop biosolids?
Loop biosolids are a nutrient-rich soil amendment created from King County wastewater. As it has for 40 years, the County produces Loop from solids extracted during the wastewater treatment process. Loop is used on farms and forests by commercial growers in both Eastern and Western Washington.
