Proposed Revisions to the Technical Guidance Manual for Individual and Subsurface Sewage Disposal Systems

Accepting Comments from June 15, 2017 to July 17, 2017

DEQ is seeking public comment on proposed revisions to its guidance on how to design, construct, and operate subsurface sewage disposal systems.

The proposed revision to the Technical Guidance Manual for Individual and Subsurface Sewage Disposal Systems (TGM) addresses dosing chambers.

The TGM is a web-based reference document used by builders and on-site wastewater system installers to select, design, and install subsurface sewage disposal systems to meet state requirements and by DEQ and public health districts to evaluate the site, proposed design, and construction of subsurface sewage disposal systems.
