Wastewater and sewer calculation

ACWWA uses residential sewer averaging: after March bills, the prior winter's actual consumption is averaged and billed through summer; after November bills, sewer charges convert to actual consumption during winter. Customers without a separate irrigation meter are charged on indoor metered water, while separate irrigation water is excluded from the sewer average. The public FAQ explains the method, while the current 2026 Appendix A provides the applicable sewer schedule.

Meter and infrastructure notes

ACWWA reads and bills water usage monthly. The public pages reviewed do not identify a specific AMR/AMI manufacturer or remote-transmission schedule, but the leak policy compares the affected period with the three-year same-season consumption average.
