Average Water Cost per CCF in the US (2026): Water + Sewer Rates

Average Water Cost per CCF: The 2026 Benchmark

If you searched for the average cost of water per CCF in the U.S., the most useful answer is a range with the sewer charge included. Water alone is only part of the bill. Many utilities also bill wastewater from metered water volume, so the combined rate is what usually drives monthly cost for commercial buildings, multifamily properties, hotels, restaurants, laundries, car washes, and hospitals.

Across the Smart Valve municipal tariff dataset, the 2026 tracked-city average is $11.53 per CCF for combined water and sewer. That is a normalized average across 50 city records and excludes fixed meter fees, taxes, stormwater charges, and account-specific surcharges.

2024 Searches vs. Current 2026 Rates

Many searches still ask for the average cost of water per CCF in the U.S. for 2024. Treat those figures as historical context only. City tariffs change frequently, and combined water-plus-sewer exposure can move faster than the water commodity rate alone. For budgeting, use the current local tariff or a current normalized benchmark like the $11.53per CCF tracked-city average above.

High-Cost City Examples

The table below uses the same tariff registry that powers the Smart Valve city water-rate database. It converts each city's combined water and sewer rate from dollars per 1,000 gallons into dollars per CCF.

Commercial vs. Residential CCF Costs

Residential searches often ask for a simple average water cost per CCF, but commercial accounts need a deeper model. A commercial bill may include a larger meter service charge, separate fire-service fees, irrigation classification, sewer volume charges, stormwater charges, infrastructure replacement fees, and seasonal or drought tiers.

That is why a 300 kGal/month property should not multiply usage by a water-only rate. In this dataset, 300 kGal/month is about 401 CCF/month. At the tracked-city average combined rate, that is about $4,626.00 per month in volumetric water and sewer exposure. A 20% reduction in billable volume would model at roughly $925.00 per month before local fixed-charge effects.

How to Lower Cost per CCF

Start with the bill, not the equipment. Confirm the customer class, meter size, CCF usage, water tiers, sewer calculation, and any local surcharges. Then separate the problem into usage reduction, rate exposure, and measurement accuracy.

• Find controllable volume: leaks, irrigation schedules, cooling tower bleed, process water, wash cycles, and fixture flow.
• Check sewer linkage: if sewer is billed from metered water, each avoided CCF can reduce two line items.
• Review meter behavior: unusual pressure, line air, or meter-size mismatch can make billed volume worth investigating.
• Use local rates: move from national averages to your city page before presenting ROI to finance.

Sources and Methodology

EPA WaterSense identifies CCF as a common water-bill unit and defines one CCF as 748 gallons. Smart Valve normalizes municipal tariff data to dollars per 1,000 gallons, then converts it back to CCF for comparison. City examples above link to local pages with source URLs and verification dates.
