Sewer Line Extension Design Checklist Update

Sewer Line Extension Design Checklist Update

The Sewer Line Extension Design Checklist has been updated to aid design engineers in understanding design requirements depicted on the plans you submit to us.

 The most significant update to the checklist outlines pressure system design plan guidelines and requirements. Additional updates include:

  • More options on required scales.
  • New matchline guidelines.
  • Requirement to add ADA sidewalk ramps on the plans.
  • Use of polymer concrete manholes and manhole inserts. 

The Sewer Line Extension Design Checklist can save you time and money by helping you avoid multiple resubmittals. Please note, the complexity of your design may require additional information not included in this checklist.

If you have any questions, please contact our office at (253) 798-2737.
