Greater Cincinnati Water Works (GCWW)

Provider briefing

How this utility’s billing works

Greater Cincinnati Water Works (GCWW) operates as a municipal department serving Greater Cincinnati region, including Cincinnati and parts of Hamilton, Butler, Warren, and Clermont counties in Ohio plus Boone County, Kentucky. 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 A fixed meter-size service/base charge plus a water commodity charge based on monthly cubic-feet consumption. For a Cincinnati city 5/8-inch residential meter in 2026, the published example uses a $9.26 monthly service charge and a $3.86-per-CCF commodity rate; GCWW implemented a 5.55% water-rate increase on January 1, 2026. Rates vary by community, meter size, and customer class, with Mason having its own residential schedule.. Bills are generated monthly. gcww's current 2026 residential rate page says water customers are billed monthly, and the billing information page says the paper bill is mailed 21 days before the due date. a consolidated gcww statement may also include sewer, stormwater, waste collection, or other municipality-specific services depending on the service address., and a typical residential cost reference is GCWW's 2026 Cincinnati example for a single-family household using 8.33 CCF, approximately 6,230 gallons, is $41.30 per month for water alone: $9.26 service charge plus $32.04 commodity charge. A 5,000-7,000-gallon household should therefore budget roughly $34-$45 monthly for GCWW water before sewer, stormwater, waste, fire-hydrant, or community-specific charges. GCWW's bill may be materially higher after the Metropolitan Sewer District winter-average sewer charge and any local stormwater services are added.. 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

GCWW acts as billing agent for the Metropolitan Sewer District of Greater Cincinnati in Cincinnati and for Mason's local sewer utility in Mason. For Cincinnati residential customers, MSD uses a winter-period average/history-based consumption method: the property's winter water usage establishes a sewer-usage cap or maximum for the rest of the year, subject to MSD's rules. Mason uses the property's average monthly consumption from December through April for its annual sewer cap. Sewer, stormwater, and other utility charges can appear on the consolidated GCWW bill but are governed by the local sewer or stormwater provider rather than GCWW's water commodity rate.

Meter and infrastructure notes

GCWW uses H2O Radio automatic meter reading: a radio unit attached to the meter transmits the reading to a vehicle driving the street, eliminating routine interior visits. The meter-reading page says regular reads support usage management and leak detection, and an actual read normally appears as 'Actual' in the bill's reading-type detail; an estimated bill can occur when access or equipment prevents a read. GCWW bills monthly, uses cubic feet as the measurement unit, and owns, installs, and maintains the meter while the customer must keep it accessible and protected from damage.
