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
WAWNC is a water authority and the reviewed billing/rate pages describe water charges, not a WAWNC wastewater or sewer billing program. Sewer charges, if applicable to a customer's property, are billed by another local provider and should not be inferred from the WAWNC water bill.
Meter and infrastructure notes
WAWNC typically obtains actual reads on 98% of accounts. Most meters have outside reading devices, and the Authority is converting customers to radio reads collected by handheld receivers from moving vehicles. If an outside device or meter cannot be read, the Authority leaves a notice and may accept a customer-supplied reading or arrange a field revisit; the applicable tariff is billed on a 90-day period.
