2026 Rate Context: Why Waukesha Bills Changed

Three bill parts

Great Water Alliance explains that Waukesha bills include water supply, return flow, and wastewater charges.

2026 estimate

For a typical residential customer using about 4,000 gallons monthly, the projected total bill is about $147/month in January 2026.

2027 estimate

The same typical-bill projection reaches about $154/month in January 2027.

Bill part
What it pays for
User action
Water supply charge
Pipes, treatment, testing, people, infrastructure, and delivery of drinking water.
Compare usage, not only dollar amount, before calling about a rate increase.
Return flow charge
Costs of returning treated water to the Great Lakes Basin through the return-flow system and pipeline.
Do not confuse this with a late fee or leak charge.
Wastewater charge
Collecting and treating wastewater, then returning treated water to the environment.
Ask whether sewer/wastewater is based on usage, average, or another local billing rule.
Irrigation meter
May eliminate wastewater charges for outdoor irrigation water.
GWA says it is cost-effective only if at least about 19,900 gallons of outdoor water are used per year.
Softener savings
Lake Michigan water is at least 60% softer than the old groundwater supply, according to GWA.
Review water softener settings so you do not overuse salt after the supply change.

Important rate note: the large PSC water-supply percentage increases discussed during the transition were not the same as the full water/sewer bill increase. Waukesha’s full bill includes water supply, return flow, and wastewater.

Rate Information Great Water Alliance FAQ WWU Rates Page

High Bill, Leak, Meter or Usage Spike

Check usage first

  • Compare gallons or consumption units, not only dollars.
  • Check whether the billing period was longer.
  • Look for irrigation, softener, toilet, water heater or outside faucet use.
  • Check if the bill includes rate transition increases.
  • Review return flow and wastewater lines separately.

Find common leaks

  • Silent toilet leak.
  • Hose bib left dripping.
  • Irrigation controller set wrong.
  • Water softener regeneration issue.
  • Private service line, basement, or water heater leak.

Call with evidence

  • Account number and service address.
  • Bill date and high-usage period.
  • Normal usage vs current usage.
  • Repair receipt or plumber note.
  • Photos and shutoff/repair date.
Question in user’s mind
Fast answer
Next action
“Why did my Waukesha bill jump?”
Could be usage, leak, irrigation, rate phase-in, return flow charge, wastewater, billing period, or past-due balance.
Separate bill lines first, then call WWU if usage is unexplained.
“Is this because of Lake Michigan water?”
Possibly partly. GWA rate projections include new supply and return-flow costs.
Compare your usage and the rate line, not just the total amount.
“Can I get outdoor-water credit?”
Waukesha has an irrigation meter path; GWA says it may only pay off if outdoor usage is at least about 19,900 gallons/year.
Ask WWU about irrigation meter application, cost, and payback before installing.
“Do I still need a water softener?”
Lake Michigan water is much softer than the old groundwater supply.
Adjust softener settings or ask a plumber/water professional to avoid wasting salt.
High-bill script: “My Waukesha Water bill increased from about [normal amount/usage] to [new amount/usage]. Can you help me separate water supply, return flow, wastewater, and usage? I also checked [toilet/softener/irrigation/faucets] and found [result].”

Lake Michigan Water Transition: What Customers Still Ask

Transition completed

Waukesha began the switch to Lake Michigan water on October 9, 2023. The Great Water Alliance says the transition is now complete and questions should go to WWU.

Supply source

After transition, treated Lake Michigan water is supplied by the City of Milwaukee to Waukesha’s distribution system.

Return flow

Waukesha’s return-flow system sends treated water back to the Great Lakes Basin, a requirement of the approval to use Lake Michigan water.

Customer concern
Plain-English answer
What to do
Water taste changed
Lake Michigan water may taste different because it has different mineral content than old groundwater.
Flush cold water if directed; report persistent taste/odor concerns to WWU.
Water looks discolored
During/after major water movement, sediment can be stirred up in mains or plumbing.
Avoid laundry until clear and contact WWU if it continues.
Softener settings
Lake Michigan water is at least 60% softer than Waukesha’s former groundwater supply, according to GWA.
Reset softener hardness setting or ask service company; do not keep old setting blindly.
Why return flow exists
Waukesha must return treated water to the Great Lakes Basin after using Lake Michigan water.
Look for “return flow” as a normal bill component, not a penalty.
Why rates rose
Rates include the cost of new supply, infrastructure, wastewater, and return-flow operations.
Use the GWA rate page to understand bill components before disputing.

Concern
What matters
Best user action
PFAS
EPA UCMR 5 monitoring records exist for Waukesha Water Utility.
Check official EPA/DNR records and the latest WWU Consumer Confidence Report before buying filters.
Radium history
Waukesha’s former groundwater supply had naturally occurring radium issues; the Lake Michigan supply transition was the long-term compliance solution.
For current safety questions, use the latest CCR and call WWU.
Lead
Lead risk often depends on household plumbing and service line material, not only utility source water.
Use cold water for drinking/cooking, flush stagnant water, and ask WWU about service-line information if concerned.
Hardness / softener
GWA says Lake Michigan water is at least 60% softer than Waukesha’s former groundwater supply.
Adjust softener settings to avoid unnecessary salt use and extra cost.
Private well
Private wells are separate from municipal compliance records.
Use a certified Wisconsin lab for private well testing.
