What changed
Greater Cincinnati Water Works published 2026 commercial water-rate information showing a 5.55% water rate increase effective Jan. 1, 2026. The city document explains that commercial water cost is based on meter size plus water used.
The document is water-only, which is important. Businesses still need to review sewer, stormwater, refuse, taxes, and other utility charges separately before estimating total bill impact.
Commercial impact model
GCWW gives an inside-city example for a 3-inch meter using 450 CCF per month, or 336,600 gallons. The published monthly water bill example is $1,574.91, with an annual water cost of $18,898.92.
If that same account reduced usage by 20% to 360 CCF, the directional water-only bill would fall to about $1,282/month under the same 2026 tier structure and service charge. That is roughly $293/month, or $3,510/year, before any sewer linkage or other charges.
What operators should check first
Use the GCWW example as a format, not a substitute for your bill. Start with meter size, service area, and monthly CCF, then calculate commodity charges by tier.
Smart Valve is relevant to the usage-based portion of the bill. It will not reduce the fixed service charge, and Cincinnati customers should separately confirm whether sewer or other utility charges track water consumption.
