Instructions for Adjustment Requests

California American Water may provide an adjustment for high bills as a result of excessive water use for the following scenarios:

  1. Leak at Property: Covers leaks within (interior plumbing or appliances) and outside (service line) of the structure.
  2. High Use – Cause Known: Covers excessive water use for which the cause is known. As example, a family member or gardener accidently left outside hose running for an extended period of time.  Other examples are a timing/cycling issue on irrigation equipment.
  3. High Use – Cause Unknown: Covers excessive water use for which the cause is unknown.  As example, high use is experienced for a single billing period and then usage patterns return to normal.  Field investigation is unable to determine the cause of higher than expected water use.
