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 or account-scheduled; the statement controls the billing period.
- Rate structure
- Metered water and sewer rates with fixed charges, consumption charges, and the Clean Rivers Impervious Area Charge (CRIAC); FY2026 rates apply beginning October 1, 2025.
- Wastewater and sewer calculation
- Sewer service is billed with water consumption and fixed/area-based charges. The official calculator incorporates water usage, sewer usage, and CRIAC; the reviewed pages did not state a single universal winter-average formula for all residential accounts.
- Meter reading
- DC Water provides usage history through My DC Water and uses customer meters, but the reviewed pages did not identify one universal AMI/AMR vendor or interval for every service address.
