Sewer Extensions & Modifications: Changing the Sewer Line

Extensions, additions, or other modifications to the sanitary sewer collection system require a sanitary sewer extension permit from the Minnesota Pollution Control Agency (MPCA) before construction can begin.

In addition to what is required by the MPCA, any project located within the WLSSD service area must be reviewed by WLSSD to ensure that the project is consistent with the approved comprehensive plan for the respective community(s).

Applications for these permits must first be submitted to WLSSD for review and consideration by WLSSD staff and Board of Directors. If the application is approved by the WLSSD Board, it is forwarded to the MPCA for further review. If the application is incomplete, it will not be considered and will be returned.

 Application Process:

1. Fill out a Sanitary Sewer Extension Permit Application. Answer each question completely and provide as much information as possible. Extra sheets may be attached if necessary.
2. Attach maps, photos and/or other materials that will assist in the review process.
3. Submit application at least 10 days prior to a scheduled WLSSD Planning Committee Meeting. Contact us for schedule.
