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 or bimonthly depending on the customer account and route. WaterOne's rules expressly contain separate monthly-bill and bimonthly-bill provisions.
- Rate structure
- Metered consumption with account-specific fixed/service charges and rate blocks; WaterOne adopted 2026 rates effective January 1, 2026. The official budget announcement says the planned adjustment was 2.9% and about $1.65 per month for a typical residential customer.
- Residential cost reference
- Approximately the prior typical residential amount plus $1.65 per month under WaterOne's 2026 budget announcement; the reviewed public release does not publish the complete 5,000-7,000 gallon bill calculation.
- Wastewater and sewer calculation
- Johnson County Wastewater bills sanitary sewer using water-usage data provided by WaterOne. The county explains that billing-cycle changes align wastewater billing with the WaterOne drinking-water cycle; the reviewed pages do not state a single universal winter-average or percentage formula.
- Meter reading
- WaterOne's customer dashboard provides usage views and high-usage alerts. The rules distinguish monthly and bimonthly accounts, while the reviewed pages do not identify a single AMI transmission interval for every meter.
