Miami-Dade 2026-27 Commercial Water and Wastewater Rates

What the October 2026 schedule says

Source-reported facts: Miami-Dade Water and Sewer publishes a 2026-27 schedule effective October 1, 2026. The non-residential table applies to commercial or mixed commercial-use properties served by Miami-Dade Water and Sewer; another provider or service area may use a different schedule.

For a 2-inch non-residential water meter, the schedule lists a $57.36 monthly meter charge. Its water tiers are $0.5416 per CCF for 0-24 CCF, $4.6789 for 25-56 CCF, $6.2809 for 57-136 CCF, and $11.0557 for 137 CCF and above.

Why meter size changes the calculation

Miami-Dade changes both the monthly charge and the water-tier thresholds by meter size. A 2-inch schedule is therefore useful as a worked reference, but it cannot be substituted for a 4-inch, 6-inch, or other account.

Hotels, restaurants, car washes, mixed-use multifamily assets, offices, healthcare facilities, laundries, industrial users, and campuses should confirm the printed meter size, billing period, customer class, and service provider before applying these rates.

Wastewater can be a second usage-linked charge

For a 2-inch non-residential account, the schedule lists a $79.12 monthly wastewater base charge. Wastewater flow is $1.8712 per CCF for the first 3 CCF and $8.8600 per CCF after the first 3 CCF.

A bill review must confirm that wastewater volume actually follows the water meter. Deduct meters, process-water treatment, account adjustments, minimums, or other utility rules can change the chargeable wastewater volume.

Directional 300-to-240 CCF example

Assume a monthly 2-inch non-residential account moves from 300 CCF to 240 CCF. All 60 avoided CCF are above the 137-CCF water threshold, so the scheduled water portion is 60 × $11.0557, or $663.34. If billed wastewater volume also falls by 60 CCF, the wastewater portion is 60 × $8.8600, or $531.60.

Together, that is about $1,194.94 in monthly variable-charge exposure. It is not a promise of a 20 percent whole-bill reduction: the $57.36 water charge, $79.12 wastewater base, stormwater, taxes, other fees, and any non-volume lines remain outside the example. Site feasibility and bill rules must also be confirmed.

Check restriction surcharges before using the top tier

The schedule’s conservation-surcharge table keeps the fourth water tier at $11.0557 during permanent or Phase I restrictions for this reference meter. It lists higher fourth-tier rates for Phase II, III, and IV restrictions. Do not apply a higher phase unless the current restriction status and the bill show that it applies.

Confirm meter size, billed CCF, billing period, tier reached, wastewater base and flow lines, restriction phase, stormwater, taxes, and any account-specific adjustments. Reproduce the utility math before forecasting a change.

Where an account assessment fits

A Smart Valve assessment starts with 12 months of bills, the meter and account class, the site’s operating context, and the utility’s wastewater basis. The output should separate fixed charges from variable exposure and label each assumption.

The worked example is a rate calculation, not evidence that a particular Miami-Dade site will reduce usage. Any site estimate should be tested against comparable operating periods and post-install utility bills.
