Portland, Tennessee 2026 Commercial Water, Sewer, and Stormwater Bill Checks
Portland, Tennessee’s July 2026 commercial water and sewer schedule: inside/outside classes, first blocks, $18 meter base, stormwater, and a bounded bill model.
Direct answer
Portland, Tennessee’s July 1 commercial schedule separates location, customer class, an $18 commercial meter base, usage-linked water and sewer blocks, and impervious-area stormwater. In one declared inside-city commercial example, 100,000 to 80,000 gallons changes included lines from $2,683.26 to $2,152.86—a $530.40 modeled difference. D2 guidance is voluntary; stormwater and other lines are excluded.

Choose the service path before applying a Portland rate
The City separates commercial from industrial service and inside-city from outside-city service. The declared model uses only the inside-city commercial path.
| Account or bill fact | Official schedule treatment |
|---|---|
| Inside commercial water | $21.53 for the first 2,000 gallons, then $8.61 per 1,000 gallons. The separate commercial water meter base is $18.00. |
| Outside commercial water | $37.20 for the first 2,000 gallons, then $14.88 per 1,000 gallons. Do not transfer the inside-city model. |
| Inside industrial water | $26.12 for the first 2,000 gallons, then $10.45 per 1,000 gallons. Industrial is not the commercial class. |
| Outside industrial water | $39.90 for the first 2,000 gallons, then $15.96 per 1,000 gallons. Confirm both class and location. |
| Inside commercial sewer | $44.77 for the first 2,000 gallons, then $17.91 per 1,000 gallons. The City says sewer is calculated from water usage. |
| Outside commercial sewer | $63.55 for the first 2,000 gallons, then $25.42 per 1,000 gallons. It is outside the declared model. |
| Industrial sewer | Inside industrial is $48.51 then $19.40 per 1,000 gallons; outside industrial is $68.83 then $27.54 per 1,000 gallons. |
| Commercial stormwater | Inside-city commercial and industrial fees are based on impervious square footage, from $24 to $2,912 in the listed tiers. They do not change with this gallon model. |
| D2 alert | The active City alert asks for voluntary reductions. It does not establish a mandatory restriction or drought surcharge. Recheck before changing operations. |
Current official schedule
The July 1 rates separate class and city-boundary status
Portland’s current rate page marks the water and sewer tables effective July 1, 2026. Commercial and industrial columns differ, and each column has separate inside-city and outside-city first-block and overage values.
The City’s adopted Ordinance 22-77 describes the July 2026 step as a 2.5% increase across the rate structures. It cites operating and material costs, a TDEC consent order, and capital improvements among the drivers. The current rate page controls the dollar values used here.
Water mechanics
The commercial base and first block are different bill components
The City lists an $18 commercial water meter base. For an inside-city commercial account, it then lists $21.53 for the first 2,000 gallons and $8.61 for each additional 1,000 gallons.
The first-block charge is usage-linked, not a fixed meter fee. It stays equal in the two declared model columns only because both scenarios remain above 2,000 gallons. A low-volume account needs a different calculation.
Sewer amplification
Inside commercial sewer is the larger usage-linked line
The inside-city commercial sewer schedule lists $44.77 for the first 2,000 gallons and $17.91 for each additional 1,000 gallons. The rate page says sewer is calculated from water usage.
That makes the listed sewer overage higher than the water overage in the declared account. Confirm the actual bill’s class, service location, billed gallons, adjustments, and any account-specific treatment before forecasting.
Separate property charge
Impervious-area stormwater stays outside a water-volume model
Portland’s commercial and industrial stormwater schedule is based on square footage of impervious surface. The listed tiers run from $24 for the smallest band to $2,912 for properties above 1.5 million square feet.
Changing metered gallons does not change impervious area. Keep stormwater visible in a complete bill review, but do not count it as usage-reducible exposure unless the City establishes a separate qualifying rule or credit.
Current operating notice
D2 guidance is voluntary as checked August 2
The City’s active alert places Portland in a D2 voluntary-reduction phase and asks customers to reduce nonessential use. It does not state a current mandatory commercial restriction or drought surcharge.
Drought status can change faster than a rate schedule. Recheck the live alert before changing irrigation, cleaning, process, or other operating plans, and keep compliance decisions separate from this bill arithmetic.
Smart Valve analysis — declared partial-bill example
One inside-city commercial account at 100,000 versus 80,000 gallons
The model applies the current commercial meter base, inside-city water blocks, and inside-city sewer blocks. Sewer is assumed to equal metered water as stated on the rate page.
Scroll the table horizontally to compare all columns.
| Included line | 100,000 gal | 80,000 gal | Difference |
|---|---|---|---|
| Commercial water meter base | $18.00 | $18.00 | $0.00 |
| Water — first 2,000 gallons | $21.53 | $21.53 | $0.00 |
| Water — gallons above 2,000 | $843.78 | $671.58 | $172.20 |
| Sewer — first 2,000 gallons | $44.77 | $44.77 | $0.00 |
| Sewer — gallons above 2,000 | $1,755.18 | $1,396.98 | $358.20 |
| Declared included subtotal | $2,683.26 | $2,152.86 | $530.40 |
The $530.40 is the modeled difference between two included partial-bill subtotals. It is not a City bill quote or promised saving. Stormwater, sanitation, industrial or outside-city rates, drought escalation, taxes, penalties, adjustments, special service, and site feasibility are excluded.
20% usage check
$530.40
Included-line modeled difference at 20% lower volume
Twenty fewer kgal changes the included water overage by $172.20 and the included sewer overage by $358.20. The $18 meter base and both first-block amounts remain equal in these two columns.
Boundary: This is reproducible partial-bill arithmetic under declared assumptions, not guaranteed savings. Stormwater is impervious-area based, and every excluded or account-specific line requires separate review.
Decision checklist
What to check first on the bill
- 1Confirm the bill is issued by the City of Portland Department of Utilities and identify inside-city or outside-city service.
- 2Confirm commercial or industrial class before selecting either schedule.
- 3Keep the $18 commercial water meter base separate from the first 2,000-gallon charge.
- 4Recalculate the first block and overage from the actual billed gallons.
- 5Verify that billed commercial sewer follows water usage on the actual account.
- 6Identify the property’s impervious-area stormwater tier and keep it outside the gallon model.
- 7Check the live drought alert before changing operating practices.
- 8Separate sanitation, taxes, penalties, adjustments, special service, and every other printed line.
Scope boundary
Where Smart Valve realistically fits
After class, location, bill period, and usage-linked lines are verified, a property team can examine leaks, operating uses, pressure conditions, and other feasible ways to change metered volume. Because the declared sewer line follows water usage, it can amplify the usage-linked exposure.
Smart Valve does not change Portland’s $18 meter base, first-block rules, customer class, city boundary, impervious-area stormwater, drought requirements, sanitation, taxes, penalties, or any other fixed or unverified line. No device fit, usage change, or bill result is guaranteed.

Frequently asked questions
What are Portland, Tennessee’s inside-city commercial water rates for July 2026?
The City lists an $18 commercial water meter base, $21.53 for the first 2,000 gallons, and $8.61 per 1,000 gallons above 2,000 for inside-city commercial service.
How is Portland commercial sewer calculated?
The City says sewer is calculated from water usage. Inside-city commercial sewer is $44.77 for the first 2,000 gallons and $17.91 per 1,000 gallons above 2,000.
Can lower metered water use reduce Portland commercial stormwater fees?
Not under the inspected schedule. Commercial and industrial stormwater is based on impervious square footage, so it stays outside this gallon-reduction model.
Is Portland’s current D2 alert mandatory for businesses?
The active alert requested voluntary reductions when checked August 2, 2026. Businesses should recheck the live notice because drought status and operating guidance can change.
