Leak relief and household assistance

A high water bill may have a path to review

Hidden plumbing failures can produce an alarming bill before the problem is visible. This guide separates what California-American Water Company - Duarte Service Area publicly describes from the practical steps every customer can take while requesting help.

Provider-specific review

What the public record says about a leak adjustment

California American Water's formal Adjustment Request process covers excessive-use bills caused by a leak inside the property or in an outside service line, a known cause such as irrigation left running, or a single unexplained high-use period followed by normal use and a field investigation. The customer should first stop the leak or correct the cause, retain repair documentation, and submit the request within six months of the occurrence. The form may be submitted digitally, emailed to csc.correspondencebilling@amwater.com, faxed to 618-433-4569, or mailed to California American Water, P.O. Box 2798, Camden, NJ 08010, Attn: Adjustment Request. Processing can take up to 20 business days; the company advises paying a normal bill while the request is pending, says the open balance is not subject to collection during processing, and sends an approval or denial letter. The reviewed public materials do not state a universal percentage or lifetime credit cap; the adjustment is determined under the company's investigation and tariff policy.

Utility assistance

Customer assistance and eligibility

The CPUC Schedule CA-CAP gives qualifying low-income Duarte residential customers a discounted tariff rather than a single flat credit. Effective January 1, 2026 for Southern Division Los Angeles Service Areas including Duarte, CAP usage rates are $0.5236 per 100 gallons for the first 85 CGL, $0.6109 for the next 50, $0.9153 for the next 163, and $1.0324 above 298 CGL. The CAP 5/8 x 3/4-inch general-metered service charge is $19.46 per month. Eligibility requires the qualifying residential account and primary residence, with income self-certification or requested verification under current California American Water and CPUC guidelines; customers should confirm the current annual income thresholds and enrollment status with the company.

State and federal connections

Where to ask for broader aid

Duarte customers can apply for California American Water's CPUC-regulated Customer Assistance Program/H2O Help to Others and can request deferred, reduced, or installment payments for up to 12 months. California American Water also publishes a Hardship Grant for residential customers who have received a shutoff notice or are at risk of disconnection; for California service areas outside Monterey, the application is through Dollar Energy at https://www.dollarenergy.org/MyApp. The reviewed Duarte materials do not publish a dedicated LIHWAP intake URL or a named local charity, so customers should call 1-888-237-1333, use the CAP and hardship links, and separately check current California, Los Angeles County, and nonprofit assistance programs.

Leak and assistance notes

Build the file before asking California-American Water Company - Duarte Service Area for relief

A high bill can have several causes, including a hidden plumbing failure, irrigation use, a meter issue, a change in occupancy, or a rate adjustment. The provider’s leak policy determines whether any credit is available; an unusually high bill does not automatically qualify.

Keep a dated record of the reading, the suspected source, the repair, the contractor or parts receipt, and the return to normal use. Ask whether the utility requires a specific form, a licensed repair, a meter test, photos, or a request within a fixed number of days.

For income-related difficulty, ask about local assistance, payment arrangements, state programs, and community referrals separately from a leak adjustment. These programs often use different applications, documents, funding limits, and deadlines.
