How this utility’s billing works
City of Janesville Water Utility / Utility Billing Office operates as a municipal department serving City of Janesville. Customers should use the provider’s current account-specific bill and official customer-service instructions as the final authority for deadlines, balances, and service requests.

These descriptions are useful planning benchmarks; actual charges can change with meter size, usage, sewer averaging, local taxes, drought stages, or account-specific fees.
Wastewater and sewer calculation
The City uses the same basement water meter as the basis for wastewater billing. Customers may reduce wastewater charges by separately metering water that does not enter the sanitary sewer, such as lawn/garden sprinkling, using a customer-funded clear-water meter.
Meter and infrastructure notes
The same basement meter measures water and supports wastewater billing; Wisconsin requires the City to test approximately 2,500 meters annually. The reviewed pages do not identify the meter vendor or remote-transmission interval.
