Community relations

Public involvement essential to water pollution control

Recent public involvement activities are affecting plans for control options for combined sewer overflows (CSOs) along Puget Sound beaches.

When John and Jane Q. Public speak, King County's Wastewater Treatment Division listens.

That's been standard operating procedure for the regional public utility since before it began operating in 1959. Public comment has played an essential role ever since.

The Wastewater Treatment Division's community relations efforts include the following:

  • Providing information to help the public understand the need for the project, alternatives and solutions.
  • Coordinating public outreach with public notification requirements of environmental review and permitting.
  • Providing opportunities for public comment on facility siting and facility design elements, such as aesthetics, architecture and landscape design.

The community services staff also conducts various public information and outreach activities to foster an informed, well-educated public that understands the need for division programs and the public good that comes from them:

Community Engagement Guide
King County has developed a Community Engagement Guide to promote effective engagement and customer service with all county communities. This guide builds on the county's Strategic Plan as well as the Equity and Social Justice Ordinance.
