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
- Dominion bills its wholesale customer under the service agreement; a residential billing frequency is not published by Dominion. The retail authority separately bills end users.
- Rate structure
- Wholesale seasonal volumetric rates effective January 1, 2026. For Sterling Ranch CAB, detached and attached residential units have a $62.20 monthly fixed water rate and water usage of $6.35 per 1,000 gallons in November-April and $7.65 per 1,000 gallons in May-October. Irrigation is $62.20 per EQR monthly plus $8.00 per 1,000 gallons, and construction water is $13.10 per 1,000 gallons. Dominion rules allow a water-shortage surcharge during defined drought or shortage conditions.
- Residential cost reference
- Dominion's wholesale detached-residential component is $62.20 fixed plus seasonal usage; at 5,000 gallons this is approximately $93.95 in winter or $100.45 in summer before the $25.00 wholesale sewer fixed charge, $7.90 per 1,000-gallon sewer charge, and any retail authority charges. The end-user bill is not equal to this wholesale amount because Sterling Ranch CAB adds retail distribution and collection charges.
- Wastewater and sewer calculation
- The 2026 Dominion wholesale sewer rate for a detached or attached residential unit is $25.00 monthly plus $7.90 per 1,000 gallons. Indoor-only attached or multifamily units have a $16.80 fixed charge. These are wholesale charges to Sterling Ranch CAB; the retail authority determines how end-user wastewater use is measured and billed.
- Meter reading
- Dominion operates wholesale transmission, wastewater conveyance, treatment, and supply infrastructure, while the retail authority develops the distribution and collection system and bills users. Dominion's public pages do not identify end-user meter technology or a residential read schedule.
