Wastewater and sewer calculation
Residential wastewater is billed at a $14.91 monthly base fee plus $3.21 per 1,000 gallons under the schedule effective November 1, 2025. The City uses its Wastewater Averaging Method: depending on the route, the annual residential average is calculated from meter usage covering November, December, January, and February, with the exact read-to-read period determined by the customer’s meter-read dates. The City states that the average wastewater calculation starts with the November read and ends with the February read, and the resulting average is used to limit or establish the residential wastewater usage charge rather than simply charging every month’s outdoor-water consumption as sewer.
Meter and infrastructure notes
The City’s customer portal exposes hourly, daily, and monthly consumption graphs, continuous-use and threshold alerts, comparisons, and downloadable XML consumption data. The portal states that the previous day’s use is available daily with approximately a four-hour latency window, which indicates advanced connected consumption telemetry rather than only a periodic manual read. The public customer pages do not identify the AMI manufacturer or radio network. Billing remains monthly, and the wastewater average is tied to the customer’s November-through-February meter-read periods.
