Area notes
- Household-size gallon suggestions are convenience defaults. You can overwrite them with your own monthly usage estimate.
- Residential wastewater usage is capped at 8,000 gallons for billing.
- The common 5/8" x 3/4" meter size is selected by default.
- This estimator is designed for resident budgeting and neighborhood comparison, not as an official utility bill.
- Port St. Lucie uses a formula-style late fee in this model, while St. Lucie County uses the published flat per-bill late payment charge.
Why this helps
Utility rates are public, but turning them into a real budget still takes work
Rate schedules are public, but real-life questions usually sound different: what will a 2-person household pay, what changes if the bill is late, and what should I budget for the first month after turning service on? Enter the gallons from your last bill for the most useful comparison.
Effective dates
Dated residential schedules, checked October 3, 2026
The embedded defaults use Port St. Lucie residential rates effective October 1, 2025 and St. Lucie County residential rates effective August 1, 2026, including the county's published $6 late-payment charge and Port St. Lucie's formula-based late-fee logic.
Methodology and guardrails
How this tool should be used
Methodology
The estimator converts published residential rate schedules into monthly scenarios for standard use, late payment, and move-in budgeting.
Key assumptions
Select the provider named on your bill: city boundaries do not establish the serving utility. Usage suggestions come from the city guide, not a measured county average. The model excludes taxes, payment-processing fees, irrigation and commercial service, prior balances and account-specific adjustments. City deposits are not modeled. County wastewater-only service is excluded because the published schedule does not clearly explain how its two listed charges apply.
Not professional advice
This is not an official utility statement or final account quote. Confirm the latest rates, deposits, and fees directly with the serving utility before relying on the estimate.
