Provider briefing
How this utility’s billing works
Tualatin Valley Water District operates as a public water authority serving Washington County and TVWD service areas west of Portland. Customers should use the provider’s current account-specific bill and official customer-service instructions as the final authority for deadlines, balances, and service requests.
The published water-rate framework is described as Two-block water structure with a fixed meter charge and volume rates per CCF. Effective November 1, 2026, a 5/8-inch meter has a $32.32 monthly or $64.64 bimonthly fixed charge; residential Block 1 is 0-28 CCF per bimonthly period at $10.69 and Block 2 is 29 or more CCF at $15.23. One CCF equals 748 gallons. The November 2026 increase is phased and affects fixed and volume charges.. Bills are generated bimonthly billing for water, with fixed charges shown monthly and bimonthly. tvwd's typical single-family residence uses 5,236 gallons or 7 ccf per month; sewer and surface-water charges are set separately by clean water services or the applicable agency., and a typical residential cost reference is For a typical 5/8-inch single-family account using 7 CCF per month, TVWD's November 2026 published example gives a $32.32 fixed charge plus approximately $128.28 volume charge, or $160.60 monthly for the above-average example. A lower-volume 7 CCF household is within the first bimonthly block and should use the current residential rate table; sewer and surface-water charges are separate.. These descriptions are useful planning benchmarks; actual charges can change with meter size, usage, sewer averaging, local taxes, drought stages, or account-specific fees.
Wastewater and sewer calculation
TVWD does not set the sewer and surface-water charges in the reviewed rate process; Clean Water Services is the separate agency responsible for those components. TVWD's water bill therefore may include externally set wastewater or surface-water items, and no universal TVWD winter-average formula is asserted here.
Meter and infrastructure notes
TVWD bills water bimonthly and publishes usage in CCF. The reviewed public pages do not identify one universal AMI vendor, hourly transmission interval, or route calendar; the official billing account provides the current read and consumption information for each service address.
