Project Design Standards

Disclaimer

These standards have been adopted by King County's Wastewater Treatment Division (WTD).

All drawings for WTD projects, whether produced by County employees or by consultants, must comply with these Standards documents.

These standards have not been adopted by other County departments. If you are producing drawings for a department other than WTD, check the project requirements for that department. Do not rely on these Standards for other departmental work.

These documents are subject to revision without notice. A CD for a given project will not necessarily be current for subsequent projects. Before starting a new project, please request a CD with the current version of these Standards to ensure you have the latest revisions.
