Bill, Rates and Line Items Users Actually Search For
Water supply
Pays for source water, treatment, testing, distribution pipes, storage and WWU water infrastructure.
Return flow
Waukesha added a return flow charge to help pay for the 23-mile system that returns treated water to the Great Lakes Basin.
Wastewater
Pays for collecting, treating and returning wastewater safely to the environment.
| Searcher question | Direct answer | Action |
|---|---|---|
| Why did the total bill rise? | Great Water Alliance explains the bill includes water supply/return flow and wastewater costs; Lake Michigan infrastructure and ongoing operations affect rates. | Compare which line changed: water supply, return flow, wastewater, late fee, or usage. |
| What are the projected bill amounts? | Typical monthly bills were projected from $102 in Jan. 2023 to $117 in Oct. 2023, $135 in Oct. 2024, $147 in Jan. 2026, and $154 in Jan. 2027. | Use the current WWU 2026 Rates page before estimating your exact account. |
| Is this paid by property taxes? | Great Water Alliance says water and wastewater projects are paid by users through rates, not property tax dollars. | Do not compare it to your property tax bill; compare usage and utility rate lines. |
| Why Lake Michigan water? | Waukesha’s previous deep aquifer source was depleted and had naturally occurring contaminants including radium; long-term groundwater use was not sustainable. | Use WWU/GWA pages for water-source questions, not old groundwater assumptions. |
| Is Lake Michigan water softer? | GWA says Lake Michigan water is at least 60% softer than the previous groundwater supply. | Review softener settings or removal rebate before buying salt/equipment. |

Lake Michigan Water: Taste, Softness, Flushing and Special Users
100% Lake Michigan
Waukesha switched to 100% Lake Michigan water from Milwaukee Water Works in 2023.
60% softer
Lake Michigan water is at least 60% softer than Waukesha’s prior groundwater supply.
Chloramine
Milwaukee uses chloramines. Aquarium owners and dialysis users should follow specialized guidance.
Pressure change
Some south/southeast areas of the Fox River may notice higher pressure due to new tower infrastructure.
| Issue | What official guidance says | What to do at home |
|---|---|---|
| Temporary rusty/discolored water | Can happen when sediment/minerals break loose during flushing or water chemistry changes. | Run cold water until clear; avoid laundry until water clears. |
| Flush house plumbing | GWA suggests removing faucet aerators, running cold faucets wide open for 3-5 minutes, flushing toilets 2-3 times, then cleaning/reinstalling aerators. | Use cold water, not hot; clean aerators after flushing. |
| Filters / RO / softeners | Filters and softeners may collect sediment during water changes or flushing. | Bypass filters/softeners when directed; resume after water runs clear. |
| Chlorine-like smell or taste | Temporary changes can be aesthetic; the water must meet regulatory standards. | If unusual taste, smell or color lasts more than 3 days, call WWU at 262-521-5272. |
| Water softener decision | Lake Michigan water is about 8 grains hardness compared with prior groundwater around 21 grains. | Try optimized settings or removal before buying new softener equipment. |
Special-use reminder: dialysis patients, aquarium owners, fishpond owners, food/beverage businesses, labs, and manufacturers should not rely on general taste guidance. Ask WWU and your specialist what applies to your process.
High Waukesha Water Bill: Find the Cause Before You Dispute
Check usage first
Compare this bill with last month and the same month last year. Outdoor use can make warm months look abnormal.
Toilet leaks
A running toilet can waste serious water. Dye test before calling.
Line item check
Make sure the increase is water usage, not wastewater, return flow, rate change, late fee, or another charge.
| Check | What to do | Why it matters |
|---|---|---|
| Toilet | Add dye/food coloring to tank, do not flush, wait. Color in bowl suggests a leak. | Silent toilet leaks are common and expensive. |
| Water softener | Check if it is regenerating too often or stuck cycling. | Lake Michigan water may need different softener settings. |
| Irrigation / hose bibs | Check sprinklers, outdoor taps, hoses, and timer programs. | Summer outdoor use can change the entire bill. |
| Meter data | Ask whether usage appears continuous overnight. | Continuous usage usually points to leaks or running equipment. |
| Water audit | WWU says home audits can help reduce water/sewer bills and simple conservation can cut usage by as much as 30%. | Good next step when no obvious leak is visible. |
| Proof packet | Keep bill, meter photo, repair receipt, plumber note, date found, date fixed. | Needed if asking for review or adjustment. |
