  • Solid Waste Management Plan - The Solid Waste Management Plan updates the City of Seattle’s programs and services to prevent waste, increase recycling and composting, and improve services.
  • Facilities Plan - The Solid Waste Facilities Master Plan was prepared to address the critical need to upgrade or replace the existing transfer stations before they fail.
  • Recycling and Waste Reduction Study (Zero Waste Study) - This study, completed in 2007, evaluated both new strategies and existing programs adopted previously under the guiding principle of “zero waste” as originally laid out in the 1998 Seattle Solid Waste Comprehensive Plan, On the Path to Sustainability. Zero Waste and collection strategies with the potential to divert significant tonnage away from landfill disposal were identified in this five month comprehensive study.


Stormwater Management Plan
The City of Seattle Stormwater Management Plan was developed for compliance with the Ecology issued 2007 NPDES Phase I Municipal Stormwater Permit and is designed to:

  • Protect water quality
  • Reduce the discharge of pollutants to the “maximum extent practicable”
  • Satisfy appropriate requirements of the Clean Water Act
  • Meet state requirements to use all known, available, and reasonable methods to prevent and control pollution to waters of the state


Drinking Water Planning
Seattle Public Utilities (SPU) participates in and develops a number of plans for meeting current and future water demands, maintaining the water system, and meeting drinking water quality regulations.

Every six years, under regulations adopted by the Washington Department of Health, SPU prepares a Water System Plan. These plans provide direction for current and future management and operation of the water system that serves Seattle and a number of nearby cities and water districts.
