For an inside-city residential account using 4,000 gallons, Casselberry’s rate listing starts with a $12.32 water base and $17.49 sewer base. The first-block usage charges are $2.31 and $6.91 per 1,000 gallons respectively.
Inside-city check
- Water: $12.32 + 4 × $2.31 = $21.56
- Sewer: $17.49 + 4 × $6.91 = $45.13
- Metered services: $66.69
- Stormwater: $10.35
- Garbage: $27.16
- Listed pre-tax subtotal: $104.20
The same 4,000-gallon metered water-and-sewer comparison for the posted outside-city classification is $75.62. That $8.93 difference makes classification worth checking before investigating the meter arithmetic.
Reconcile in this order
Confirm the account’s service territory, meter class, billing dates, and 4,000-gallon input through Utility Customer Service. Match each fixed line separately. Only then compare taxes, prior balances, adjustments, or other services.
The $104.20 figure is not a bill forecast. It intentionally stops before tax and does not model higher usage blocks. It is a reproducible audit point for five named rows under one usage assumption.
