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.
- Rate structure
- Wholesale and groundwater-benefit-zone charge structure, not a residential tiered retail rate. The FY2026–27 PAWS report and current-charge page distinguish surface-water, treated-water contract/non-contract, groundwater benefit zone, agricultural, and municipal/industrial charges. Total surface-water and treated-water charges are composed of the published basic user charge plus the applicable water-master, contract, or non-contract surcharge; retailers then set their own retail meter, usage, sewer, and pass-through rates.
