How Tiered Water Billing Works
Many US water utilities use tiered (inclining block) pricing to encourage conservation. This calculator uses approximate average rates: $15 fixed monthly charge, $2.00/CCF for the first 2 CCF, $3.50/CCF for 3–5 CCF, and $5.50/CCF for 6+ CCF. One CCF equals 748 gallons or about 2.83 cubic meters.
The average US household uses 6–10 CCF per month, with peak usage in summer due to lawn irrigation. Only the usage within each tier is billed at that tier's rate — not your entire usage. Rates vary widely by utility, state, and drought conditions.
Fixing a single dripping faucet can save up to 3,000 gallons per year. Low-flow showerheads and efficient appliances are the most effective long-term water savers.
