Dayton Water and Sewer Rates: What to Check Before Disputing a Bill
The City lists 2026 water/sewer service rates effective January 1, 2026 for premises within the corporate limits. Always verify your exact meter size, billing period and service location.
| Rate item | 2026 listed detail | Why it matters |
|---|---|---|
| 5/8” monthly minimum | Water: $18.60; Sewer: $22.25. | Many residential customers have a small meter, but confirm your meter size. |
| 5/8” quarterly minimum | Water: $23.51; Sewer: $28.12. | Check whether your account is monthly or quarterly before comparing bills. |
| Monthly water usage tier | First 3,300 CF/1,000: $44.67; next 30,000: $42.57; next 133,000: $40.16; next 167,000: $32.92; over 333,300: $30.43. | Usage tiers and meter readings matter more than only the total amount. |
| Monthly sewer usage tier | First 3,300 CF/1,000: $32.55; next 30,000: $24.96; over 33,300: $22.09. | Leak adjustments may only affect sewer in certain situations, not all water use. |
| Well Field Protection Fund | Rates are subject to charges up to $1.00 per 1,000 CF added for the Well Field Protection Fund. | This can appear as part of the bill beyond base water/sewer calculations. |
| Net vs gross amount | The City notes the net amount is a 5% discount if paid by the specified day; gross amount is payable thereafter. | Paying by the net due date can affect what amount you owe. |
High Dayton Water Bill? Check These Before Calling
Watch the meter
Dayton’s leak page says about 90% of residential meters are in the front sidewalk. If the red flow-indicator triangle or sweep hand moves while all water is off, a leak or malfunction may exist.
Test toilets first
The City says toilets are the most common cause of leaks. Put food coloring in the tank; if color appears in the bowl within 5 minutes without flushing, the toilet leaks.
Check irrigation and softener
Shut off the irrigation anti-siphon valve or bypass the water softener and recheck the meter indicator to isolate the problem.
| High-bill issue | Dayton guidance | Best next step |
|---|---|---|
| Leak did not enter sanitary sewer | The City FAQ says the sanitary sewer portion may be credited only if the leaked water did not enter the sanitary sewer. | Document the leak, repair and where the water went before requesting review. |
| Leak in yard | The City repairs from the water main to the property line. After service crosses the property line, maintenance is the landowner’s responsibility. | Determine whether the leak is before or after the property line. |
| Pool filled with garden hose | The City FAQ says the Water Department does not credit sewer charges for filling swimming pools with a garden hose. | Check official pool-fill/fire hydrant permit rules before filling large pools. |
| Main service line leak | If the red triangle moves after the home shutoff valve is off, the leak may be between the shutoff valve and the meter. | Call a plumber or the City depending on location and responsibility. |
Buying Property, Renting or Managing a Dayton Water Account
Bill follows the property
The City says when a property changes hands in Dayton, responsibility for the water/utility bill remains with the property.

For more information, the Water Quality page lists the Water Supply and Treatment Division at 937-333-6093.
Local Dayton Water Tips That Save Time
Do not miss the net date
Dayton’s cycle includes a net payment due date on Day 16 and gross payment due on Day 30. If you want the net amount, do not wait until the end of the cycle.
Retail cash payment needs the barcode
If paying cash at participating retailers such as Family Dollar or CVS, bring the barcode from the invoice, past-due notice or shutoff notice.
Check property bills before closing
Because responsibility remains with the property, buyers and real estate agents should confirm the water/utility balance before closing.
Leak location matters
Before requesting an adjustment, determine whether leaked water entered the sanitary sewer and whether the leak is on the customer side of the property line.
