Wastewater and sewer calculation
Residential sewer maintenance is billed on the same monthly City utility bill and the published schedule lists $0.35 per 100 cubic feet. The reviewed City materials do not describe winter averaging, a separate sewer cap, or a flat percentage of water consumption; therefore the defensible public calculation is a usage-linked charge based on the metered billing units, with the exact account line item controlling. Street sweeping is a separate monthly charge and trash is not part of the City water bill.
Meter and infrastructure notes
The City operates the municipal system for more than 14,300 connections, with eight active wells, a 4.2-million-gallon underground reservoir, five surface tanks totaling 9.5 million gallons, and approximately 135 miles of distribution pipeline.
