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
- Monthly. The San Diego County tariff states that general metered service is billed every month; charges are a readiness-to-serve meter charge plus water quantity charges.
- Rate structure
- Increasing-block residential quantity tariff by 100-gallon CGL plus a monthly meter service charge. In the current San Diego County Schedule SD-1, residential first 59.8 CGL is $0.6386 per 100 gallons, next 52.4 CGL $0.7299, next 112.2 CGL $1.0747 and usage over 224.4 CGL $1.4217; a 5/8x3/4-inch meter service charge is listed at $7.40 in the tariff document. Separate wastewater, taxes and regulatory surcharges may apply by service area.
- Residential cost reference
- Approximately $111 per month for a 5/8-inch residential account using 6,000 gallons, using the cited tariff's $7.40 service charge and a rough 60-CGL calculation through the residential blocks. Actual Coronado bills may include current CPUC-approved surcharges, wastewater from another provider and taxes, so the MyWater bill calculator should control.
- Wastewater and sewer calculation
- California American Water's Coronado water tariff is for water service; wastewater may be supplied and billed by a separate local agency. The company calculator asks whether wastewater service applies and which wastewater area, so sewer is not a universal flat percentage of water intake and must be determined from the account/service area.
- Meter reading
- MyWater provides current usage and usage comparisons, while California American Water also publishes AMI meter information. The Coronado tariff bills general metered service monthly; the reviewed public pages do not state a universal meter-read day or radio-transmission interval.
