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 Contra Costa Water District (CCWD) 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

CCWD’s Leak Adjustment program requires the customer to submit an online request or mail a letter describing how and when the leak occurred, when it was repaired, the account number, and a daytime phone number. Attach proof of repair such as a plumber’s invoice or parts receipt; if the customer or another person made the repair with parts already on hand and has no receipt, the customer must state that in the form or letter. Mail requests go to CCWD, Attn: Leak Adjustment, 1331 Concord Avenue, Concord, CA 94520. CCWD aims to send a written response within 15 business days from the date of the next bill and commonly applies a credit after the next bill; the District tells customers to pay the current bill in full to avoid late penalties. After investigation, CCWD may credit up to 50% of the quantity charge attributable to excess use above normal use; Lifeline participants may receive a 100% credit on excess quantity billed. CCWD must find that the meter was accurate, there was no intentional/negligent misuse or tampering, the customer promptly investigated and repaired the leak beyond the delivery point, and there was no adjustment during the prior 24 months. Normal use is generally the representative average from the same billing period or periods in the preceding two years. The credit cannot cover non-quantity charges, may cover no more than four months/two billing periods, cannot cover bills older than one year, and is limited to one adjustment in any 24-month period; CCWD states the determination is discretionary with no right of appeal.

Utility assistance

Customer assistance and eligibility

CCWD’s Lifeline Water Rate Program reduces the daily service charge by 50% for low-income treated-water customers who are at least 58 years old or receive permanent disability insurance benefits from the Social Security Administration. The current May 2026 annual adjusted-gross-income limits are $59,400 for one household member, $67,900 for two, $76,400 for three, $84,850 for four, $91,650 for five, $98,450 for six, $105,250 for seven, and $112,050 for eight or more. The application is mailed to Contra Costa Water District, Lifeline Program, P.O. Box H20, Concord, CA 94524; customers can call 925-688-8000 with questions. The benefit is a service-charge discount, not a universal usage-rate waiver, and the program’s eligibility period and renewal requirements should be confirmed on the current application.

State and federal connections

Where to ask for broader aid

CCWD’s current published affordability workflow is the local Lifeline Water Rate Program and direct customer-service assistance at 925-688-8000; the District also directs customers needing payment help to 925-688-8040 from its leak-adjustment page. The reviewed 2026 CCWD pages do not publish a direct LIHWAP application URL, a state water-assistance benefit-posting process, or a federal arrears grant intake. Customers should ask CCWD whether a state or county program is currently available for their address and should separately contact the local wastewater provider, because CCWD does not bill a universal sewer charge. Lifeline participants receive the more favorable leak-adjustment treatment described above.

Leak and assistance notes

Build the file before asking Contra Costa Water District (CCWD) 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.
