Provider briefing
How this utility’s billing works
Portland Water District operates as a public water authority serving Greater Portland regional service area. 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 FY27 rates effective July 1, 2026 use a daily base charge plus metered volumetric water and sewer charges. Water is $8.833 per ccf (748 gallons); residential sewer is $14.24 per ccf; the quarterly base is $0.8906 per day, and the 90-day minimum bill is $40.08. A residential flood-safety fee is $0.04 per dwelling unit per day.. Bills are generated most single-family residential customers are billed quarterly and their meters are read every three months; some accounts are bimonthly or monthly. the district’s terms also allow monthly, bimonthly, quarterly, or seasonal billing., and a typical residential cost reference is Approximately $267.95 for a typical 90-day bill at 15 ccf (about 11,220 gallons, or 5 ccf/month) before stormwater/other property charges: $132.50 water volume, $213.60 residential sewer volume, about $80.15 quarterly base, and $3.60 flood-safety fee. Because PWD bills most single-family accounts quarterly, a 5,000-gallon monthly comparison is best represented as a quarterly bill rather than a monthly invoice.. 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
Most customers do not have a separate wastewater meter, so sewer volume is related to metered water use; depending on account type, PWD may use winter water use to calculate sewer charges. FY27 residential sewer volume is $14.24 per ccf. The District also bills municipal sewer charges in some communities as collection agent, so local municipality rules can affect the final wastewater amount.
Meter and infrastructure notes
PWD is replacing nearly all 55,000 meters with Sensus non-mechanical AMI meters using a secure FlexNet network; installations began in October 2025 and continue over three years. The planned portal supports daily or hourly usage, alerts, and leak detection; legacy single-family reads occur every three months.
