Ocoee publishes residential water and sewer rates to four decimal places. Keeping those inputs until the end makes it possible to compare the calculation with the City’s rounding rather than losing precision at every tier.
Rate inputs for a 3/4-inch meter
From the October 1, 2025 schedule:
- water base: $15.9715;
- sewer base: $28.7880;
- first 6,000 water gallons: $1.7305 per thousand;
- next 6,000 water gallons: $2.1808 per thousand;
- 12,000–18,000 water gallons: $2.7295 per thousand; and
- sewer: $4.1223 per thousand through 12,000 gallons, then $0 above that residential cap.
Three usage checks
| Use | Water component | Sewer component | Combined before other rows |
|---|---|---|---|
| 4,000 gal. | $15.9715 + 4×$1.7305 = $22.8935 | $28.7880 + 4×$4.1223 = $45.2772 | $68.1707 |
| 8,000 gal. | $15.9715 + 6×$1.7305 + 2×$2.1808 = $30.7161 | $28.7880 + 8×$4.1223 = $61.7664 | $92.4825 |
| 15,000 gal. | $15.9715 + 6×$1.7305 + 6×$2.1808 + 3×$2.7295 = $47.6278 | $28.7880 + 12×$4.1223 = $78.2556 | $125.8834 |
Rounded only after combining, those examples are approximately $68.17, $92.48, and $125.88. The City’s billing system may round service components or tiers differently, so use the unrounded trail when asking about a small variance.
At 15,000 gallons, rounding water and sewer separately gives $47.63 + $78.26 = $125.89, one cent more than rounding their combined $125.8834 once. That is an identifiable rounding-order difference, not permission to alter a rate input.
Boundaries of the model
This does not include reclaimed water, solid waste, taxes, deposits, late charges, adjustments, or a meter larger than 3/4 inch. It also does not determine whether Ocoee provides both services to the address. Verify those facts in the City utility account.
The calculation is useful as a line-item check, not as a prediction of the statement total.
Method: LSL rechecked both pages of the City’s rate PDF and the Utilities landing on September 20, 2026, then independently evaluated each formula. The original article’s 8,000- and 15,000-gallon water results were arithmetic errors, not City rate changes; the corrected results above preserve the published four-decimal inputs.
