Wastewater Plan Submittal Requirements by Project Type

COVID-19 Information

The COVID-19 emergency is an evolving situation. At this time, wastewater staff are continuing to review plans during the emergency.

To facilitate review while staff are working remotely, all submittals, including required forms and supporting documents, should be provided via email; the requirement for paper copies is suspended at this time. The DNR prefers that documents are provided via a download link (ftp servers, etc.) in an email in order to prevent overwhelming email inbox capacity. If that option is not available to you, DNR staff can receive emails up to 20 MB.

Email submittals to Jason Knutson.

Please ignore any references to paper submittals on this or other pages for wastewater plan submittals as long as this banner is present.


A complete plan submittal varies with the type of project.
