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
- San Diego County residential meters are read and billed approximately every 30 days, although California American Water general rate information permits regular residential billing monthly or quarterly depending on service arrangement. The San Diego sample bill describes an approximately 30-day meter-reading period and the customer bill itself controls the exact due date.
- Rate structure
- Conservation-oriented increasing block tiers for metered residential water, plus a meter-size monthly readiness-to-serve charge and regulatory or municipal surcharges. The current San Diego County tariff applies to Coronado and Imperial Beach: first 59.8 CGL at $0.7749 per 100 gallons, next 52.4 CGL at $0.8707, next 112.2 CGL at $1.2821, and all use above 224.4 CGL at $1.7218. For a 5/8 x 3/4-inch meter the monthly service charge is $7.55; the tariff also lists a 2% City of Imperial Beach franchise or business-license surcharge and other schedule-based surcharges.
- Residential cost reference
- For a typical 5/8 x 3/4-inch residential meter, the 2026 San Diego tariff produces approximately $46.30 in base water charges at 5,000 gallons and approximately $62.78 at 7,000 gallons, before regulatory, CAP, municipal, or other bill surcharges. A Southern San Diego 2026 average-bill notice using 56.7 CGL shows a published illustrative total of $86.53 including fees, taxes, and surcharges; the actual Coronado bill varies by meter size, surcharge layer, and whether the local sewer provider bills separately.
- Wastewater and sewer calculation
- California American Water serves the San Diego County water district, but the reviewed San Diego tariff does not publish a Coronado wastewater charge. Sewer service for a Coronado property may be billed by a separate municipal or regional sewer provider rather than on the California American Water water bill; customers should use the sewer line or local agency named on their statement. California American Water does publish wastewater tariffs for other California service areas, so those rates must not be substituted for Coronado.
- Meter reading
- The San Diego County District is fully metered. The provider sample bill states that meters are read in 100-cubic-foot units approximately once every 30 days, with customer billing converted to 100-gallon increments called CGL; one unit is 748 gallons. MyWater exposes usage history and alerts, but the reviewed Coronado and San Diego pages do not verify an AMI hourly-transmission network, so the reliable published description is regular route meter reading with online historical usage access.
- New-account deposit
- Rule 7 requires a $25 deposit for residential metered service using no more than a 5/8 x 3/4-inch meter when bills are monthly, or $50 when bills are bimonthly. Other service may require twice the estimated average periodic bill, subject to the tariff limits. Credit may instead be established by owning the premises, providing a satisfactory guarantor, or showing 12 consecutive months of prior service paid without nonpayment disconnection. Deposits are applied to unpaid bills at discontinuance, the excess is refunded, and interest is paid at 7% annually after the deposit has been held for 12 consecutive months or when service ends, subject to the rule.
- Activation or transfer fee
- MyWater and the company voice system support residential service turn-on, turn-off, and transfer workflows, but a separate routine resident name-transfer fee was not published on the accessible 2026 San Diego customer pages. The CA-FEES tariff contains infrastructure connection fees for new service connections, including legacy listed amounts of $2,000 for a 5/8 x 3/4-inch meter, $3,000 for a 3/4-inch meter, $5,000 for a 1-inch meter, $10,000 for a 1.5-inch meter, and $16,000 for a 2-inch meter; these are new infrastructure connection charges, not a normal move-in account-transfer fee.
