Wastewater Plan Submittal Requirements by Project Type

Due to the closure of GEF3, the department has updated mailing addresses for plan submittals. For mail sent via any non-USPS carriers (UPS, FedEX, Spee-Dee, etc.) please use the updated address below.

DNR has returned to requiring paper submittals for most wastewater plan reviews. Some documents no longer require paper copies. View the Project Types listings below to verify document submittal requirements for each project type. Note that an electronic plan submittal portal is in development, so electronic submittal procedures will be changing in the future.


A complete plan submittal varies with the type of project.

  • Click the Project Type title below to view the submittal requirements for a particular project type.
  • If you are looking for a specific plan review submittal form, see the Plan Review Submittal Forms table at the bottom of the page.
