Wastewater and sewer calculation

Residential wastewater is billed bimonthly using consumption tiers and a winter-average concept. For 2026 single-family accounts, the published bimonthly charges are $157.06 for 0-4 CCF, $204.18 for 5-18 CCF, and $247.82 for 19 or more CCF. Winter billing uses actual water use; non-winter billing generally uses the account's average winter consumption, with the published average winter use noted as 11 CCF. Residential accounts do not receive a sewer credit under the current leak-adjustment policy.

Meter and infrastructure notes

AWWD divides the District into eight meter-reading routes and bills every other month. Meters are read using a computerized handheld device; if a meter cannot be accessed, the District may estimate the reading. Customers can use the District's My Water Meter and leak-finding resources, but the reviewed pages do not identify a universal AMI vendor or hourly transmission interval.
