Our Sustainability Program provides leadership for green and sustainable initiatives of the Wastewater Treatment Division (WTD) in support of King County's Strategic Climate Action Plan and Green Building Ordinance. Our work strengthens WTD’s green building best practices, and we advocate for equity and social justice to be considered on all capital projects to ensure positive outcomes for the communities we serve. The program routinely shares and receives information from regional partners in a collaborative effort to address climate impacts.

Sustainability plays an important role in WTD’s ability to implement innovative waste-to-resource products and services while ensuring our treatment plants and built projects operate at peak efficiency—taking sustainability from concept to practice.
