Provider briefing

How this utility’s billing works

Metro Water Services (MWS), Metropolitan Government of Nashville and Davidson County operates as a municipal department serving Nashville-Davidson County and portions of surrounding counties. 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 residential tiers with fixed meter charges, 10% water and 10% sewer Infrastructure Replacement fees, and a 9.25% Tennessee sales tax on water sales. For 2026, a 5/8-inch meter has a $6.12 monthly water fixed charge and $9.78 sewer fixed charge; the first 2 CCF (1,496 gallons) are included in those fixed charges. Residential volumetric rates are $4.20/CCF for 3-6 CCF, $5.05/CCF for 7-10 CCF, and $6.31/CCF above 10 CCF; sewer volume is $7.02/CCF. Rates increased 3% on January 1, 2026 and appeared on February bills. Stormwater is a separate impervious-area tier.. Bills are generated monthly. mws bills water and wastewater together from the electronic meter reading, and davidson county residents receive a stormwater user fee on the same bill. the statement shows the bill date, due date, current charges, replacement fees, meter information, usage history, and payment instructions., and a typical residential cost reference is For a standard 5/8-inch residential meter using 5,000-7,000 gallons (about 6.68-9.36 CCF), the 2026 water-and-sewer charges calculate to approximately $76-$112 before water sales tax and stormwater, or roughly $78-$116 after the 9.25% water tax and before the residential stormwater fee. A typical 2,001-6,000-square-foot impervious-area property adds $6 per month for stormwater, while the official stormwater tiers range from $0 to $11 for ordinary residential properties. Actual bills vary with meter size, exact CCF, sprinkler use, taxes, and payment or service fees.. 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

MWS bills sewer from the same metered water consumption, with a $9.78 5/8-inch fixed sewer charge and a $7.02/CCF 2026 residential volumetric sewer rate, plus a 10% Sewer Infrastructure Replacement fee. MWS provides a seasonal sewer adjustment for residential accounts during April-November: lawn sprinkling and car washing are presumed not to enter the sewer, so the maximum sewer charge is based on the January-February-March winter-quarter average plus 30%. This is commonly called the sprinkler credit and is designed to prevent outdoor summer water from being charged as wastewater. Davidson County stormwater is not sewer; it is separately based on impervious square footage.

Meter and infrastructure notes

MWS reads more than 220,000 water meters each month. The current bill guide says readings are captured by an electronic reading device, and the online Premium account provides smart-meter usage data, bill history, and downloadable consumption analysis. MWS's billing-review system flags negative usage, a 300% average increase, five months of zero usage, a 50% average decrease, missing readings, and duplicate readings for staff review; a field visit may inspect the meter for damage or visible leaks. Customers must keep the meter accessible at all times. The public materials do not promise hourly transmission for every residence, so the safest description is monthly electronic meter reading with smart-meter data available where the property has been upgraded.
