Sewer Service Area


Sewer Service Area (SSA) Plans have been developed for twenty-six 208 Water Quality Areas within the Designated ‘Section 208’ Water Quality Planning Area of the East Central Region.

SSA Plans are required under Wisconsin Administrative Code Chapter NR 121 for certain communities within Wisconsin and assist in maintaining and improving water quality within the State by outlining areas which are able to accommodate sewered development in a cost effective and well-managed environment. SSA Plans delineate Environmentally Sensitive Areas which preclude such development. SSA Plans also serve as the 20-year plan for the community’s wastewater treatment plant and collection infrastructure and are used as guidance during the Wastewater Facilities Planning process established under Wisconsin Administration Code Chapter NR 110.

Additional information on Sewer Service Area Planning can be found on the Wisconsin Department of Natural Resources Sewer Service Area Planning Web Page

Water Quality Management Plan ‘208’ Conformance Review Process

As a contracted agency with the WDNR, ECWRPC is responsible for the review of public sanitary sewer extensions, private lateral extensions, facilities plans, and the subsequent issuance of Water Quality Management (WQM) Plan Conformance Letters (sometimes referred to as ‘208’ letters). These letters are required by WDNR to ensure that the proposed project is consistent with the existing Water Quality Management SSA Plan. Please note that the ‘208’ review process can take up to 30 days and submittals should allow for this!

More information on the conformance review process can be found in the following documents:

Please contact Joe Stephenson with questions or comments.

SSA Plan Amendment Process

SSA Plan amendments and updates are reviewed/completed by staff and submitted to the Commission’s Community Facilities Committee (CFC) and/or the full Commission for approval. Once the Commission has approved the plan modification, it is submitted to the WDNR for final review and certification. Please note that the plan amendment process can take up to 3 months from start to finish! The Commission’s SSA Amendment procedures are contained within the individual SSA Plan documents.
