Billing and account research from public material
Provider-specific research notes are displayed separately from fields that contain only an unavailable-information marker. Read qualifiers in each note and verify current account terms with the provider.
- Billing frequency
- Monthly water rates and examples are published. Sewer billing frequency and the responsible municipality can vary because wastewater service is often a collaboration between PWD and the member city or town.
- Rate structure
- Meter-size minimum charge with an included cubic-foot allowance, then volumetric charges; seasonal rates differ for surface and deep mains and member versus non-member communities. Effective January 1, 2026, a member 5/8-inch meter has a $12.86 minimum with 100 cubic feet included, while non-member 5/8-inch service has a $14.80 minimum with 100 cubic feet included.
- Residential cost reference
- For a typical non-member 5/8-inch residential account, the published 2026 table estimates $37.12 at 5,400 gallons/month and $48.28 at 7,200 gallons/month for water only. Portland member examples show $22.97 at 500 cubic feet/month; local wastewater charges are additional.
- Wastewater and sewer calculation
- PWD does not provide one universal sewer tariff because wastewater is often billed by the local municipality. The rate page lists Portland municipal wastewater at $13 minimum for the first HCF and $13 per additional HCF under the listed effective date, while other member communities have different minimums and per-HCF charges. Customers must use the municipality named on their bill for the exact sewer calculation.
- Meter reading
- PWD launched a major AMI replacement project for nearly all 55,000 meters, with installation beginning October 2025 and continuing for three years. The project is intended to improve leak detection and emergency response; the public page does not state a universal completion date or hourly transmission interval.
