Billing and account research from public material
Provider-specific research notes are displayed separately from fields that contain only an unavailable-information marker. Read qualifiers in each note and verify current account terms with the provider.
- Billing frequency
- Monthly billing for all customer classes is documented in Wisconsin DNR materials; the ACH form states that deductions occur on the 15th of the month the bill is due. Customers should follow the due date printed on the current bill.
- Rate structure
- PSC-regulated municipal tariff with fixed meter/readiness charges and volumetric water charges; Waukesha transitioned from groundwater to Lake Michigan water through the Great Water Alliance. A verified current 2026 residential tariff table was not exposed in the reviewed official pages, so exact blocks and meter charges are not reproduced here.
- Wastewater and sewer calculation
- Waukesha bills water and sewer through the combined Water Utility account. The reviewed official sources do not publish the current 2026 sewer formula or a winter-average calculation. Wisconsin PSC guidance states that sewer charges are not regulated by the PSC and that utilities may apply a written leak policy to water while retaining discretion over sewer adjustments.
- Meter reading
- Waukesha's verified 2023 Wisconsin DNR report documents monthly billing and a high-consumption audit that can send a postcard to customers who may have a leak. The reviewed official documents do not specify whether all customer meters are AMI/AMR or publish a fixed read route; the utility's billing portal and customer-service department provide account-specific usage information.
- New-account deposit
- The reviewed official Waukesha documents do not publish a universal residential startup deposit, credit-check waiver or deposit-return period. New service applications and account requirements must be confirmed with the utility at 115 Delafield Street or (262) 521-5272.
- Activation or transfer fee
- The reviewed official sources do not state a universal residential activation or transfer fee. Official ACH materials identify new-account ACH setup and monthly deduction timing, while start/stop service requests should be handled through the utility's customer-service portal or (262) 521-5272.
