Biosolids in Agriculture
For 20 years, King County has partnered with farmers who use biosolids to enhance soils of agricultural land in Eastern Washington. Learn more.
Reclaimed Water Contributes to Wetland Habitat
King County produces Class A reclaimed water, which is safe for irrigating turf grass and food crops, and suitable for industrial and environmental enhancement purposes.

Energy Audit at West Point Treatment Plant
In 2009, the West Point Wastewater Treatment Plant was responsible for 9 percent of King County Government’s energy consumption. The Resource Recovery's Energy Program has been developing a strategy and scope for a systemwide energy audit of the County's West Point Treatment Plant. The audit will look at energy use distribution to identify energy conservation methods. King County's recently adopted Energy Plan (soon to be available online), outlines the goals and objectives of energy conservation and generation in the County's Wastewater Treatment Division. Learn more about the Division's Energy Program.
Membrane Bioreactor Systems
King County is now using membrane bioreactors (MBRs) at two wastewater treatment facilities. This wastewater treatment system is effective in producing very high quality water that only requires disinfection to make it suitable for irrigation, industrial process water, and other environmental uses such as, wetland enhancement. Learn more about the pilot testing that King County conducted before choosing to use this new treatment technology.
Creating Resources From Wastewater
The Wastewater Treatment Division's Resource Recovery Group works to recover and recycle beneficial resources from the wastewater treatment process, producing biosolids, reclaimed water and biogas. Resources from wastewater provide us with healthy crops, renewable energy, green sports fields, lush gardens, robust forests, and vibrant wetlands - all nourished with King County's recycled resources.
