City of Waukesha water diversion applicationPermits 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
  • Permits for pipeline stream crossings, wetland crossings and Root River outfall
  • Water Supply Service Area plan approval
  • DNR public water systems construction plan 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 a final EIS and a WEPA compliance determination.

Staff from the DNR and Public Service Commission of Wisconsin (PSC) have been meeting with the City to discuss the needed information. The City has been working to develop this information, and is expected to provide it in early 2018.

The public will have an opportunity to comment on draft permits at a public informational meeting in 2018. The DNR will update the EIS, and issue the final EIS and WEPA compliance determination. Finally, the DNR will issue permits.
