Wastewater and sewer calculation
Wastewater is calculated as a $21.95 monthly base facility charge plus $7.07 per 1,000 gallons of billed consumption, with the usage component capped at 8,000 gallons per month according to the current County calculator. The public 2026 calculator and rate page reviewed do not describe a winter-average sewer formula.
Meter and infrastructure notes
The public 2026 material supports monthly billing and monthly consumption calculations but does not identify a universal AMR/AMI vendor, radio network, or hourly transmission schedule. The County's calculator and leak-adjustment rules rely on monthly meter reads, and customers should contact Water Resources for account-specific read or estimated-bill questions.
