Billing and account research from public material
Provider-specific research notes are displayed separately from fields that contain only an unavailable-information marker. Read qualifiers in each note and verify current account terms with the provider.
- Billing frequency
- Bimonthly, six times per year. AWWD divides its service area into eight meter-reading and billing cycles; bills are due 21 days after the billing date.
- Rate structure
- Bimonthly meter base charge including a usage allowance, followed by increasing-block CCF pricing. Effective January 1, 2026, a standard 3/4 by 5/8-inch residential meter has a $46.86 bimonthly water base including 4 CCF; usage is $3.69 per CCF for 5-14 CCF, $4.46 for 15-30 CCF, and $5.39 above 30 CCF. One CCF is 748 gallons, and District rates increased 15.5% for water and 9.5% for wastewater in 2026.
- Residential cost reference
- AWWD's 2026 comparison uses a typical household at approximately 7 CCF per month, or 5,236 gallons. The water portion is about $41.88 per month on the District's published comparison; the bimonthly calculation is $46.86 base plus 10 CCF of included-period use at $3.69, or about $83.76 for two months and $41.88 monthly equivalent. The published wastewater comparison is about $102.09 monthly, making a typical combined water-and-wastewater estimate approximately $143.97 per month before utility taxes and other charges.
- 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 reading
- 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.
- New-account deposit
- The reviewed AWWD customer pages do not publish a universal residential startup deposit or credit-check waiver. A $15 one-time service charge applies to a new account or an account name change with a change in occupancy. Customers whose service was locked for nonpayment may also receive a meter-unlock fee and should confirm any account-specific deposit with Customer Service.
- Activation or transfer fee
- The initial account setup or occupancy name-change service charge is $15. If water service is restored after a lock, AWWD states that customers should allow 2-3 business days for a meter unlock; the reviewed pages do not state a separate universal transfer fee beyond the $15 service charge.
