Using the Mount Dora schedule effective March 3, 2026, consider one inside-city residential scenario using the ordinary per-unit availability charges, not the master-metered multifamily rows: 1,000 kWh of electric use and 5,000 gallons for both water and sewer.
| Service | Arithmetic | Subtotal |
|---|---|---|
| Electric | $12.06 + 1,000 × ($0.05434 + $0.05112) | $117.52 |
| Water | $13.60 + 5,000 × $0.0026091 | $26.65 |
| Sewer | $41.61 + 5,000 × $0.0096767 | $89.99 |
| Sanitation | Fixed row | $25.68 |
| Stormwater | Fixed row | $18.90 |
| Five-service subtotal | Sum above | $278.74 |
Full precision is retained until each service is rounded to cents. The electric row includes both the posted energy and power-cost components. Water and sewer inputs here are per gallon, not per 1,000 gallons; multiplying either rate by five instead of 5,000 would undercount usage by a factor of 1,000.
What this does not model
Gross-receipts tax, utility taxes/surcharges, higher water blocks, deposits, arrears and account-specific adjustments are omitted. The published power-cost component is already included above; do not silently add it a second time. The PDF uses different water/sewer availability charges for master-metered multifamily service, and marks sanitation/stormwater unavailable in its outside-city column. This inside-city subtotal does not apply unchanged to those classifications. Confirm meter readings and service dates through Utility Services. If a statement differs, reconcile service by service rather than comparing its total due directly with $278.74.
This scenario is useful because all five inputs are visible. It is not “the average Mount Dora bill,” a claim the source data does not establish.
Method: LSL rechecked the complete March 3, 2026 rate sheet and billing page on September 20, 2026 and independently evaluated every formula. Water is $26.6455 and sewer $89.9935 before rounding each service to cents. The 5,000-gallon example remains below the rate sheet’s 8,977-gallon sewer footnote boundary and makes no claim about higher-use treatment.
