Arlington WA Commercial Utility Rates: 2026 Water, Sewer, Industrial, and Stormwater Checks
Arlington, Washington lists 2026 commercial water, sewer, industrial sewer, and stormwater rates. Commercial properties should model base charges, 100-cubic-foot usage, industrial waste strength, and the 5% utility tax.

What changed in Arlington
Source-reported facts: Arlington posts 2025/2026 commercial utility rates, with 2026 inside-city and outside-city water base charges by meter size and water consumption charges per 100 cubic feet.
The same official utility-rate page states that billed amounts include a 5% tax calculated on gross revenue from water, sewer, and stormwater utilities.
Who may be affected
This matters for Arlington commercial properties, restaurants, schools, industrial facilities, multifamily buildings with commercial-style accounts, temporary construction users, and businesses with private fire or stormwater exposure.
For 2026 inside-city service, the commercial water base charge is $37.10 for 5/8-inch to 3/4-inch meters, $51.88 for 1-inch, $66.69 for 1.5-inch, $107.41 for 2-inch, $408.01 for 3-inch, and $519.46 for 4-inch.
Why sewer and industrial charges matter
Arlington lists commercial sewer at a $78.42 base rate that includes 300 cubic feet of water, plus $8.11 per 100 cubic feet. That sewer rate can be larger than the water consumption rate, so usage changes may have a bigger effect on sewer exposure than on water alone.
Industrial accounts need separate handling. The schedule lists light industrial sewer at $479.57 for waste strength below 250 mg/l, heavy industrial sewer at $1,917.15 above 250 mg/l, and industrial analysis rates for flow, BOD, and TSS.
What a 20 percent usage reduction could mean
Directional estimate: assume an inside-city commercial account has 3,000 cubic feet of billable monthly volume and usage above the included/base amount is exposed to $3.58 per 100 cubic feet for water and $8.11 per 100 cubic feet for sewer.
A 20 percent reduction equals 600 cubic feet, or six 100-cubic-foot units. At $11.69 per 100 cubic feet combined, that is about $70.14 per month before fixed base charges, the 5% utility tax, industrial strength charges, stormwater, and site feasibility.
What to check first on your bill
Confirm inside-city or outside-city service, meter size, monthly 100-cubic-foot usage, sewer class, stormwater ESUs, and whether the account has light industrial, heavy industrial, or industrial-analysis charges.
Then separate the water base, water usage, sewer base, sewer usage, stormwater, tax, and industrial surcharges. Do not model BOD, TSS, stormwater, or fixed base charges as if they decline automatically with domestic water usage.
Where Smart Valve fits
Smart Valve may be relevant for Arlington commercial accounts with meaningful controllable metered volume. It should be modeled against usage-linked water and sewer volume only where sewer billing follows metered water.
It cannot reduce stormwater ESUs, utility tax on fixed lines, industrial strength surcharges, or fixed meter and sewer base charges.
What to Do Next
Confirm inside-city or outside-city class before applying the 2026 rate table.
Separate commercial sewer volume from water volume before estimating savings.
Flag industrial accounts for BOD, TSS, and flow-based analysis before using a standard commercial model.
