Truckee Meadows Water Authority (TMWA)

Provider briefing

How this utility’s billing works

Truckee Meadows Water Authority (TMWA) operates as a public water authority serving Reno, Sparks, and unincorporated Washoe County in the Truckee Meadows. Customers should use the provider’s current account-specific bill and official customer-service instructions as the final authority for deadlines, balances, and service requests.

The published water-rate framework is described as Increasing block/tiered metered water rates with fixed meter-size customer charges, plus a 1.5% Washoe County Regional Water Management Fee and a Reno/Sparks right-of-way toll where applicable. The 2026 residential rate sheet lists a 3/4-inch customer charge of $21.87 per billing period and commodity rates of $2.20 per 1,000 gallons for Tier 1 up to 6,000 gallons, $3.30 for Tier 2 from 6,001-25,000 gallons, and $4.39 above 25,000 gallons. The June 2026 bill reflects a 3.5% annual adjustment and the revised cost-of-service structure.. Bills are generated monthly. tmwa sends a monthly water bill showing the current charges, payment due date, usage, and local pass-through fees., and a typical residential cost reference is For a 3/4-inch residential account using 5,000 gallons in the standard 2026 schedule, the water charge is approximately $21.87 + (5 x $2.20) = $32.87 before pass-through charges. Reno/Sparks customers then generally see a 1.5% Regional Water Management Fee and 5% right-of-way toll, producing a rough water-only total of about $35.00 before any backflow charge, late amount, or separate sewer bill. TMWA supplies water; wastewater/sewer is billed by separate local agencies and is not included in this estimate.. These descriptions are useful planning benchmarks; actual charges can change with meter size, usage, sewer averaging, local taxes, drought stages, or account-specific fees.

Wastewater and sewer calculation

TMWA is a drinking-water authority and does not provide the standard sewer charge on the TMWA water bill. Reno residents generally receive sewer charges through the City of Reno, while the regional Truckee Meadows Water Reclamation Facility is jointly owned by Reno and Sparks. Sewer charges are calculated separately based on volume and equivalent domestic-strength wastewater; customers must use their city or local sewer bill for the applicable 2026 wastewater base and usage calculations.

Meter and infrastructure notes

TMWA bills metered service monthly and its new My Account portal provides advance meter-consumption data, usage analysis, transaction history, and downloadable water-use records. The 2026 rate update references automated metering as part of system cost control. The public pages do not specify a universal meter vendor or hourly transmission interval, but customer-facing portal data supports ongoing consumption monitoring rather than only an annual manual read.
