Provider briefing
How this utility’s billing works
BILLINGS CITY OF operates as a municipal department serving Billings. 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.
The published water-rate framework is described as Metered volumetric pricing with a fixed monthly charge based on meter size and increasing residential usage tiers. For inside-city residential use effective July 1, 2026, the volumetric tiers are 0–10 kgal, 11–32 kgal, 33–75 kgal, and over 75 kgal; wastewater has its own service charge and $5.95-per-kgal volumetric charge effective July 1, 2026.. Bills are generated the reviewed current rate and payment pages do not state a single universal bill-generation frequency; residential accounts are issued on recurring meter-read cycles, with each statement controlling its exact cycle and due date., and a typical residential cost reference is City FY2026 budget materials estimate a median-home monthly water charge of about $47.71, wastewater of $30.85, and stormwater of $8.81, or about $101.87 total. This is a budget estimate rather than a guaranteed 5,000–7,000-gallon bill; the exact charge varies by meter size, inside/outside-city status, tier, and stormwater classification.. 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
Wastewater is billed separately using a meter-size service charge plus a volumetric wastewater rate. The current rate table lists $5.95 per thousand gallons effective July 1, 2026, but the reviewed public table does not expose every fixed service-charge amount in its text. The account bill and current City rate table control the applicable calculation.
Meter and infrastructure notes
The reviewed public 2026 rate and payment pages do not identify residential meter communications technology or publish a universal read calendar. Bills are based on the meter readings assigned to each account.

If your issue is urgent, start with the provider’s emergency number or official payment route rather than waiting for an email response. Keep a written record of calls, confirmation numbers, notice dates, and documents you submit.
