Environmental programs

From planning our entire conveyance system to remediating sediment contamination near county outfalls for combined sewer overflows, these programs cover a wide range of services and provide the detailed planning and study necessary to design, build and upgrade our treatment system.

• Biosolids recycling
  King County's program is used as a model throughout the nation and has won many awards for its innovative and environmentally sensitive operations.
• Combined Sewer Overflow (CSO) Control Program
  Information on what a CSO is, where they are found in the King County system, and ongoing control projects.
• Conveyance System Improvement (CSI) Program
  This is an array of more than 250 miles of pipes and 42 pump stations that moves wastewater from local communities to the treatment plants. The program focuses on upgrading and improving the existing regional conveyance system as well as planning for future conveyance extensions.
• Duwamish Waterway Programs
  This portal page describes King County programs to improve water quality and sediments in the Lower Duwamish Waterway.
• Energy Recovery from wastewater
  Information about recovering energy from the wastewater treatment process, including the fuel cell demonstration pilot project.
• Environmental planning (environmental documents for public review)
  This program ensures that the Wastewater Treatment Division complies with the state and federal Environmental Policy Acts and the federal Endangered Species Act.
• Industrial Waste Program
  Designed to prevent businesses from discharging substances that can degrade the wastewater treatment process, harm workers or facilities, or affect surface-water quality.
• Reclaimed Water Program
  The Regional Wastewater Services Plan calls for the county to pursue and explore opportunities for expanded water reuse at the county's existing treatment facilities. The policies also call for the county to explore water reuse opportunities at all new treatment facilities.
• Regional Infiltration and Inflow Control Program 
  A partnership between the county and the 34 local sewer agencies to study & identify sources of inflow and infiltration into local sewer systems.
• Sediment Management Program
  Developed in the late 1990s to remediate sediment contamination near county outfalls for combined sewer overflows, or CSOs, in Seattle.
• Water Quality Trouble Call Program 
  This program supports the Wastewater Treatment Division by responding to water quality emergencies in King County.
