City of Waukesha water diversionPermits review

To implement the diversion of Lake Michigan water to the City of Waukesha (Waukesha), Waukesha must obtain all required federal, state and local permits and approvals. Waukesha has decided to obtain Lake Michigan water from the Milwaukee Water Utility. Waukesha's treated wastewater will be returned to Lake Michigan via the Root River.

Needed permits and approvals, include:

  • The Wisconsin Public Service Commission's Construction Authorization for construction required to implement the diversion
  • Wisconsin Pollutant Discharge Elimination System (WPDES) Permit for wastewater discharge to the Root River
  • Wastewater Facilities Plan approval
  • Permits for pipeline stream crossings, wetland crossings and Root River outfall
  • Water Supply Service Area plan approval
  • DNR public water systems construction plan approval
  • Wisconsin Diversion approval

Waukesha also plans to request grants from the DNR to implement the project. Prior to the issuance of any permits or grants, the DNR will issue an Environmental Impact Statement (EIS) and a Wisconsin Environmental Policy Act (WEPA) compliance determination.

Staff from the DNR and Public Service Commission of Wisconsin (PSC) have been meeting with the City to discuss needed information. The City has been working to develop this information.

The public will have an opportunity to comment on draft permits at a public informational meeting in 2019. After the EIS and WEPA compliance determination are issued, the DNR will issue permits.

Wetland and waterway permit application

The City of Waukesha submitted a wetland and waterway permit application to the department on June 28, 2019. The DNR determined the wetland and waterway permit application to be complete in December of 2018.
