Provider briefing
How this utility’s billing works
PASCO WATER DEPARTMENT operates as a municipal department serving Pasco. 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 Uniform base-plus-consumption pricing by meter size, not increasing blocks: for a single-family 3/4-inch meter inside city limits effective March 1, 2026, the water base is $31.48 and usage is $1.35 per 100 cubic feet. One hundred cubic feet equals 748 gallons. Outside-city rates are separately listed at $59.81 base and $2.57 per 100 cubic feet. City-supplied irrigation, ambulance, and storm-drain charges are separate line items.. Bills are generated monthly; utility bills are produced every month and are considered late 20 days from the billing date., and a typical residential cost reference is For an inside-city single-family residence with a 3/4-inch meter and 6,000 gallons (about 8.02 billing units of 100 cubic feet), water is approximately $42.31 ($31.48 + 8.02 x $1.35) and residential sewer is $41.33, for approximately $83.64 combined water/sewer before the separate $28.17 ambulance, $6.85 storm-drain, irrigation, or other charges. Actual bills vary by meter size, service location, and usage.. 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
Effective March 1, 2026, the rate sheet lists inside-city residential sewer at $41.33 per month and outside-city residential sewer at $62.00. The published single-family sheet does not expose a separate residential sewer consumption tier or winter-average formula; commercial accounts are explicitly charged an additional sewer fee based on water usage over 1,000 cubic feet per month. The first 1,000 cubic feet is included in the commercial/multifamily sewer base schedule.
Meter and infrastructure notes
The City’s utility-billing conversion documentation states that the billing system processes meter reads and calculates recurring base and consumption charges for approximately 24,000 accounts. The current public pages do not identify the meter manufacturer, AMI/AMR communications method, transmission interval, or exact reading schedule.

Reading this profile
A practical reference for Pasco
PASCO WATER DEPARTMENT is listed here as a municipal department. The profile separates account actions—such as paying a bill or requesting service—from explanatory material about rates, meters, wastewater, leaks, and delinquency.
Because utility rules can vary by account class, meter size, service address, billing date, and local ordinance, treat the published bill and current provider website as the final authority. Use this profile to locate the correct channel and prepare better questions for customer service.
If your issue is urgent, start with the provider’s emergency number or official payment route rather than waiting for an email response. Keep a written record of calls, confirmation numbers, notice dates, and documents you submit.
