Tulsa Commercial Utility Rates: October 2026 Bill Checks
Direct answer
Tulsa’s October 1, 2026 rate book applies to October usage on November bills. Inside-city commercial water is $4.55 per 1,000 gallons plus meter charges; industrial classes differ. Sewer depends on a winter average or return factor. Stormwater is a separate $14.65-per-ESU charge. Confirm the printed account class and billing basis.
Tulsa’s October 2026 utility rate book separates commercial and industrial water classes, sewer billing methods, meter charges, and stormwater ESUs.
$4.55
Inside commercial water
Per 1,000 gallons, plus the applicable monthly meter charge.
$11.00
Inside sewer quantity
Per 1,000 gallons under the listed winter-quarter-average or return-factor basis.
$14.65
Inside stormwater
Per ESU; the rate-book row describes 2,650 square feet of developed lot, tract, or parcel.
November
First affected bill
The cover places October 2026 consumption on November 2026 bills.

Effective date and first bill
October consumption moves to the October 1 rate book
The City of Tulsa’s current utility-rate landing page links a rate book marked effective October 1, 2026. Its cover says October 2026 consumption appears on the November 2026 bill. Commercial refuse and EMSA rates are labeled unchanged, so this article does not present those lines as part of the water, sewer, or stormwater schedule.
Match the service period before using the figures. The rate book supplies current charges, but it does not provide the prior schedule needed to calculate a percentage increase for an individual account.
Customer-class fork
Commercial and industrial water do not use one shared quantity rate
The water table separates four utility classes and two service areas. Confirm the printed class code with Utilities: a business description alone cannot establish commercial, industrial or large-industrial eligibility.
Copy the class code, service area, meter size, billed gallons, and any private fire line from the statement. The rate book applies separate meter charges to all classes and lists private fire-protection service on its own rows.
Sewer calculation boundary
Current water use does not automatically equal billed sewer quantity
For inside-city sanitary sewer, the book lists $11.00 per 1,000 gallons under either a winter-quarter-average row or a return-factor row. Its return-factor note uses billed water usage multiplied by the account’s return-factor percentage and rate. The reviewed pages do not identify an individual property’s winter average or return factor.
Industrial sewer uses another schedule: $7.80 per 1,000 gallons inside, plus listed BOD/COD, suspended-solids, and actual monitoring charges. Do not apply the ordinary $11 rate or the water-only scenario below to an industrial sewer account.
Stormwater boundary
Use Tulsa’s billed ESU instead of importing another city’s formula
The inside-city stormwater row is $14.65 per Equivalent Service Unit. The row describes one ESU as 2,650 square feet of developed lot, tract, or parcel. It does not describe that area as impervious area, so this article does not substitute an impervious-area calculation.
Record the ESU count and stormwater line from the actual statement. Lower metered water use should not be presented as reducing this separate ESU charge without an account-specific Tulsa rule that says so.
Declared water-only scenario
100 to 80 kgal changes inside commercial water volume by $91 per month
Assume one monthly inside-city account is printed as commercial and compare 100,000 with 80,000 gallons under the same $4.55-per-1,000-gallon water quantity rate.
| Line | 100 kgal | 80 kgal |
|---|---|---|
| Water | $455.00 | $364.00 |
100 × $4.55 = $455; 80 × $4.55 = $364; the modeled difference is $91. Monthly meter charges, private fire service, sewer, stormwater, refuse, EMSA, taxes, fees, adjustments, and service-period treatment are excluded. This is a same-rate usage comparison, not a full-bill forecast or guaranteed saving.
Decision checklist
What to check on the November statement
- 1Confirm City of Tulsa service, the October consumption period, and inside- or outside-city treatment.
- 2Copy the printed water class, meter size, billed gallons, and any private fire-protection line before using a quantity rate.
- 3For sewer, identify the winter-quarter average or return factor; industrial accounts should also reconcile strength and monitoring charges.
- 4For stormwater, use the billed Tulsa ESU count and keep that line outside the water-volume model.
Scope boundary
Where Smart Valve realistically fits
After the class, meter, billed volume, sewer basis, and separate charges are documented, a property team can investigate technically addressable water use such as leaks, pressure conditions, and operating loads.
Smart Valve does not change Tulsa’s rates, meter charges, sewer calculation method, industrial-strength charges, stormwater ESUs, or account classification. The 20% scenario is arithmetic only and does not promise that a site can achieve that reduction.
