Sustainability

Sustainability

King County protects public health and the environment by collecting and treating wastewater while recycling valuable resources. We deliver with a focus on sustainability.

WTD models leadership in sustainable development every day. We turn biogas from the wastewater treatment process into clean energy. We clean and recycle wastewater solids (poop and food) into a nutrient-rich soil builder for plants. We incorporate green building practices into construction projects. Our grant program helps communities improve water quality and promotes equity and social justice.

Together, the environmental, social, and economic sustainability practices of WTD support thriving, resilient neighborhoods and communities throughout the Puget Sound region.

What is sustainability?

Sustainability is defined as the long-term viability, health, and robustness of environmental, social, and economic systems. For WTD, this means:

  • healthy natural environments
  • equity, social justice, and vibrant communities
  • cost-effective capital investments, operations, and maintenance
  • resilience to future disruptions and climate adaptation
