Edmond OK 2026 Commercial Water and Sewer Rates: Winter-Average Timing
Edmond’s July 2026 commercial water and sewer rates separate meter bases, water tiers, winter-average timing, drainage, and Stage 1 rules.
Direct answer
Edmond’s July 1, 2026 nonresidential schedule combines a meter-size water base, three usage bands, and wastewater charges based on the rounded-up December–February average applied May through April. A current water reduction changes eligible water volume now, not the existing wastewater average; the separate $9-per-ESU drainage line and Stage 1 odd/even watering rule, checked July 18, follow different drivers.

Commercial bill-line map
Four Edmond bill drivers need four different checks
The July schedule does not make every line move with this month’s gallons. Classify each charge before estimating a change.
| Bill driver | What a commercial account should know |
|---|---|
| Water base and tiers | The 2-inch base includes 1,000 gallons; three nonresidential bands price the remaining volume. |
| Current wastewater line | The existing rounded winter average, not current-month use, generally controls the May–April charge. |
| Future winter average | Lower qualifying December–February use may affect a later May–April wastewater period after the average resets. |
| Drainage and Stage 1 | Drainage follows impervious area; Stage 1 is an odd/even operating rule checked July 18, not a verified surcharge. |
Official July schedule
The nonresidential water charge combines a meter base and three volume bands
Edmond’s official water-rate page says the schedule is effective July 1, 2026. For a 2-inch meter, the $328.26 monthly base includes the first 1,000 gallons. Nonresidential use from 1,001 through 3,000 gallons is $8.86 per 1,000 gallons; 3,001 through 10,000 is $9.26; and use above 10,000 is $9.86.
The model below declares one established 2-inch nonresidential account. It does not transfer a residential example, combine meters, or assume that every commercial property has the same base.
Wastewater timing
December through February use sets a later May-through-April charge
Edmond’s wastewater page says monthly charges are based on the average metered water use in December, January, and February, rounded up to the next 1,000 gallons. The recalculated wastewater charge then applies from May through April.
That lag matters. Lower use in a current summer month can change the eligible current water line without changing an already-set wastewater average. A later wastewater difference requires qualifying winter use, a verified reset, and the next application period.
Account configuration
Wastewater minimums depend on meter size and commercial-user setup
The July wastewater schedule lists a $110.17 monthly base for a 2-inch meter and a $6 charge per 1,000 gallons of the applicable average. The official page also says multiple commercial users may have the wastewater minimum multiplied by the number of users.
The example is intentionally narrower: one established 2-inch, single-commercial-user account. Edmond’s no-history cap, unit multiplication, penalties, adjustments, and other account lines stay outside the calculation and belong on the bill checklist.
Separate property charge
Drainage follows impervious area rather than metered use
Edmond’s drainage page says developed nonresidential property is charged $9 for each Equivalent Service Unit, or portion of an ESU. One ESU is 4,860 square feet of impervious area, and the reviewed page states no monthly cap.
That line is property based and is not included in the usage model. Lower metered water use should not be presented as a way to reduce the drainage charge unless Edmond publishes a different account-specific rule.
Current operating rule
Stage 1 odd/even watering is not a verified bill surcharge
Edmond’s outdoor-watering page showed Stage 1 on July 18, 2026. Odd-numbered addresses may water on odd calendar dates and even-numbered addresses on even dates.
Stage 1 affects scheduling and operations; the reviewed page does not establish a drought surcharge. Recheck the City’s live status before irrigation or other outdoor use because the operating condition can change faster than an adopted rate schedule.
System context
The City links the increase to treatment capacity and system investment
Edmond says the City Council approved the increase May 11 and announced it May 18. The City points to expansion of the Arcadia Lake water-treatment plant, aging facilities, and reduced dependence on Oklahoma City water as system drivers.
Those facts explain the rate decision but do not determine one commercial account’s bill. Meter size, billed volume, winter-average history, user configuration, and property-based drainage remain the account-level checks.
Smart Valve analysis
The example keeps the current and future billing windows separate
At 100,000 gallons, the declared water account models at $1,298.20: the $328.26 base, $17.72 in the first nonresidential band, $64.82 in the second, and $887.40 above 10,000 gallons. At 80,000 gallons, only the last band changes, producing $1,101.00 and a current water-line difference of $197.20.
Separately, if a qualifying winter average later resets from 100,000 to 80,000 gallons, the $6-per-1,000-gallon wastewater volume line changes from $600 to $480. That conditional $120 difference belongs to a later wastewater period; it is not added to the current water result.
Smart Valve analysis — two billing contexts
One established 2-inch, single-user commercial example
Compare 100,000 with 80,000 gallons under the verified July schedule. Current water and a qualifying later winter-average wastewater reset are shown as separate contexts.
Scroll the table horizontally to compare all columns.
| Included line or context | 100,000 gal | 80,000 gal | Difference |
|---|---|---|---|
| 2-inch water base, first 1,000 gal included | $328.26 | $328.26 | $0.00 |
| Water from 1,001–3,000 gal | $17.72 | $17.72 | $0.00 |
| Water from 3,001–10,000 gal | $64.82 | $64.82 | $0.00 |
| Water above 10,000 gal | $887.40 | $690.20 | $197.20 |
| Current water total | $1,298.20 | $1,101.00 | $197.20 |
| Later wastewater volume, if the winter average resets | $600.00 | $480.00 | $120.00 |
| 2-inch wastewater base | $110.17 | $110.17 | $0.00 |
Do not add $197.20 and $120.00 into one immediate result. The first is a current water-line comparison; the second is a conditional later wastewater-volume comparison after a verified winter-average reset. Drainage and Stage 1 are excluded.
20% usage check
No combined total
A 20% usage check reaches two different billing windows
The declared current water comparison changes by $197.20. A qualifying future winter-average reset from 100,000 to 80,000 gallons would separately change the later wastewater volume line by $120.00.
Boundary: The two figures apply to different billing windows and are not a savings promise. The example excludes drainage, the fixed wastewater base, no-history treatment, multiple-user minimums, penalties, adjustments, other services, and technical feasibility.
Decision checklist
What to check first on the bill
- 1Confirm the account is nonresidential and record the water and wastewater meter size.
- 2Verify whether the water base includes the first 1,000 gallons on the actual statement.
- 3Recalculate each nonresidential water band instead of applying one blended rate.
- 4Collect December, January, and February metered use and the wastewater average shown on the bill.
- 5Confirm whether the account has one commercial user, multiple users, or no qualifying billing history.
- 6Identify the separate drainage ESUs and impervious-area basis without assigning that line to water savings.
- 7Recheck the live Stage 1 status before scheduling outdoor water use.
Scope boundary
Where Smart Valve realistically fits
Smart Valve may help a facility evaluate controllable metered water volume after the actual Edmond class, meter, pressure conditions, operating uses, and billing history are confirmed. The current-water example isolates only lines supported by the official schedule.
Smart Valve does not change meter-size bases, drainage ESUs, the City’s rate, Stage 1 rules, or an already-set wastewater average. A later wastewater effect depends on qualifying winter use and Edmond’s recalculation; no result is guaranteed.

Frequently asked questions
What changed in Edmond’s commercial water and sewer schedule on July 1, 2026?
Edmond’s July schedule lists new meter-size water and wastewater bases, three nonresidential water usage bands, and a $6-per-1,000-gallon wastewater volume charge. The actual effect depends on meter size, billed use, winter-average history, and account setup.
Does lower water use immediately reduce Edmond wastewater charges?
Not necessarily. Edmond bases the May-through-April wastewater charge on the rounded-up average metered use from the prior December, January, and February. Current water use can change the current water line while an existing wastewater average remains in place.
Can lower metered water use reduce Edmond’s drainage charge?
The reviewed drainage schedule bases the nonresidential charge on impervious area at $9 per ESU or portion, with one ESU equal to 4,860 square feet. It is not a metered-water charge and is excluded from the usage model.
Does Edmond Stage 1 add a drought surcharge?
The outdoor-watering page checked July 18 describes an odd/even operating schedule and does not establish a surcharge. Recheck the live City page because the restriction stage can change.
