The Purpose of SWAC

Seattle Public Utilities' Solid Waste Advisory Committee (SWAC) is an advisory body mandated by RCW 70A.205.110 to provide recommendations and informed advice to the Utility regarding solid waste management issues.


SWAC members work with SPU’s Solid Waste Division to provide recommendations, feedback, and share community insights on programs, policies, and outreach objectives around recycling, compost, garbage, and waste prevention. SWAC members review and comment upon programs, policies, and ordinances concerning solid waste handling and disposal prior to adoption and serve as active stakeholders in long-range solid waste planning efforts.   
SWAC members contribute expertise from diverse communities and organizations, with varied professional and life experiences. SPU values partnering with SWAC members to uphold the City of Seattle’s City Values, including racial and social justice.  

SWAC members work with SPU’s Solid Waste team to provide recommendations, feedback, and share community insights into programs, policies, and outreach objectives around recycling, compost, garbage, and waste prevention. SWAC members also assist in the review of programs and policies concerning solid waste handling and disposal. In addition, members review and comments upon proposed plans, rules, policies, or ordinances prior to their adoption.
