The official schedule is dated June 1, 2025, so the 2026 amount should be rechecked against the next adopted tariff..

Reading this profile
A practical reference for Martin County, including Stuart and unincorporated county service areas
Martin County Utilities and Solid Waste is listed here as a municipal department. The profile separates account actions—such as paying a bill or requesting service—from explanatory material about rates, meters, wastewater, leaks, and delinquency.
Because utility rules can vary by account class, meter size, service address, billing date, and local ordinance, treat the published bill and current provider website as the final authority. Use this profile to locate the correct channel and prepare better questions for customer service.
If your issue is urgent, start with the provider’s emergency number or official payment route rather than waiting for an email response. Keep a written record of calls, confirmation numbers, notice dates, and documents you submit.
