All projects within the district service area boundary which install or modify publicly owned sanitary sewers must be approved by the district commission and the Wisconsin Department of Natural Resources.

A plan review fee will be charged to the customer community for projects which installs publicly owned sewers serving new users. Plan review fees are not due for review of reconstruction projects which are not adding new customers or changing the sewer service area. Plan review fees are adjusted annually.


2021 Fee

For sewer rehabilitation or replacement projects, if a sewer is being repaired or replaced at the same location, and with the same pipe size and slope, then the project is considered a "maintenance project" and plans do not need to be submitted to the District or DNR unless the project will be financed through the Clean Water Fund.

The District Commission meets twice per month. Click here for the future meeting schedule.

To have a sanitary sewer project approved by the District and DNR, a full submittal must be received a minimum of 14 calendar days in advance of a District Commission meeting. Upon approval by the Commission, the District will forward the project to DNR for final approval. Do not send projects directly to DNR for approval.

A list of items to be submitted for approval of a sanitary sewer extension can be found here. District staff will determine if the materials submitted are complete. Incomplete submittals will cause delays to the approval process.

Redevelopments are also be reviewed by District staff. Often these projects do not install any new sanitary sewers, but may impact the sanitary sewer system and trigger the collection of a “redevelopment charge”.
