Waukesha utility votes to submit PSC application seeking roughly 13% water increase

The Waukesha Water Utility Commission voted June 19 to submit an application to the Wisconsin Public Service Commission (PSC) asking for a conventional water-rate adjustment in docket 6240-WR-111. Utility staff said the filing requests updated rates based on a year-and-a-half of actual costs from the Great Water Alliance project and other finalized amortizations.

Courtney, utility staff leading the presentation, told commissioners the PSC previously approved a two-step rate schedule (effective Oct. 1, 2023 and Oct. 1, 2024) and now requires another conventional filing within two years of the docket date. Courtney said staffing gaps and annual PSC reporting timelines prompted a request for a brief extension of the filing deadline to ensure all supporting paperwork is complete. Staff estimated the water portion of bills would increase by about 13% in the proposed filing while noting the overall household bill impact is smaller when water, return flow and sewer are combined.

Why it matters: The PSC, not the commission, sets final customer rates. Commissioners and members of the public pressed staff on how long customers should expect higher costs and whether rates can fall after debt is repaid. Dan, the utility’s general manager, said the water-supply loan is structured for repayment over roughly 38 years and that pipelines are built to long lifespans with planned redundancy; because of that structure he did not expect near-term reductions in the water-supply portion of the bill even after debt is repaid. Staff said customers may see reductions in return-flow charges over time because those components can be repaired rather than duplicated.

Public questions: Two residents—Chris Wilson and Kurt Bauer—asked whether customers would see rates drop after construction debt is paid and sought clarification on whether projections were presented monthly or quarterly. Courtney and Dan explained that historical projections were often shown quarterly (the format used in some past materials) while bills are issued monthly, and that the PSC will evaluate filed rates using actual cost data rather than the earlier estimates the utility reported during the Great Water Alliance planning.

Next steps: The commission approved by voice vote a motion to submit the PSC application. The PSC’s review schedule can take 12–18 months for a conventional rate filing; the commission’s vote authorizes staff to proceed with the application but does not set final customer charges.

Sources and attribution: Quotes and figures come from the June 19 meeting presentation and public comment. The PSC filing referenced by staff is docket 6240-WR-111. The commission’s vote to submit the application was taken by voice; no roll-call vote was recorded.

What to watch: The PSC docket schedule and any additional information staff files with the application that clarifies the projected percentage impact on typical monthly bills.
