Residential outside-city A8 accounts instead use a $26 fixed sewer-average charge; inactive A9 accounts use the $9 fixed plus $1.45 water-consumption formula.
Meter and infrastructure notes
Mission installed residential and commercial automatic smart water meters through a project involving the City, Performance Services, and Sensus. The smart-meter portal is intended to show when and how customers use water, support monthly budgets and high-consumption detection, and send customer-service alerts; the reviewed project page identifies zone installation dates but does not publish an hourly read interval.
