High Golden State Water Bill: Check Usage and Leaks First
Check the meter
Golden State Water says customers are charged in Ccf. One Ccf equals 100 cubic feet, or 748 gallons.
How to read your meterToilet leak test
Golden State Water recommends putting 3 or 4 drops of food coloring in the toilet tank and waiting 15 minutes. Color in the bowl without flushing indicates a leak.
Conservation tipsUnderstand your bill
The bill includes service period, previous/current meter readings, next scheduled meter-read date, and usage measured in Ccf.
Understanding your bill| What you notice | Likely cause | Best official action |
|---|---|---|
| Usage jumped suddenly | Leak, irrigation, more people at home, meter-read timing, or outdoor use. | Read your meter |
| Toilet runs silently | Flapper or tank leak. | Use food-color test |
| Payment made after 5 p.m. | Next-business-day posting delay may make balance look unpaid. | Check posting rule |
| Bill amount is still unclear | Meter read, surcharge, rate area, unpaid balance, or account question. | Call customer service |
Meter and Ccf: A Simple Way To Read Usage
Official meter logic: Golden State Water says the meter reads like an odometer and measures cubic feet. Customers are charged for each hundred cubic feet, called Ccf. One Ccf equals 748 gallons. If the next reading is 829 and the previous reading was 817, the difference is 12 Ccf, or 1,200 cubic feet.
Step 1: Find readings
Use your bill’s previous and current meter readings or read the meter directly if safe and accessible.
Step 2: Subtract
Current reading minus previous reading equals the water used for the period.
Step 3: Convert if needed
Each Ccf equals 748 gallons, so multiply Ccf by 748 to estimate gallons.
Service Area, Rates and Local Rules Matter
Golden State Water serves many California communities, so local rates, tariffs, water quality reports, conservation stages and service-area notices may differ. Do not assume one city’s rate example applies to another service area.
Find your service area
Use the official service-area page before checking local rates, conservation rules or water quality reports.
Your service areaRates and tariffs
Golden State Water is regulated by the CPUC, and tariffs/rates vary by area and rate schedule.

California Customer Tips That Actually Help
Do not trust every payment result
Golden State Water explicitly warns that third-party websites may show outdated or inaccurate payment information. Use official links from Golden State Water first.
Service area changes the answer
A Golden State Water customer in Claremont, Los Osos, Simi Valley, San Gabriel, Arden Cordova or Barstow may have different local rate and conservation details. Start with the service-area page for local issues.
Pay before 5 p.m. when timing matters
After-5 p.m. payments post the next business day. For delinquent accounts, that one timing detail can create confusion.
Use CAP before the account is in crisis
CAP does not automatically transfer when you move, and customers must renew every two years or sooner if requested. Apply early instead of waiting until shutoff timing is close.

Golden State Water’s customer service is centralized and available 24/7 by phone. Use this map for the corporate office mailing address only; bill payments by mail should go to the official payment PO Box listed on the payment page.
