Provider-specific findings
Relief research for this provider
The notes below may document a route, rule, or explicit public-information limit. General preparation steps are not represented as utility policy.
- Emergency reporting route
- The Bayshore district main and after-hours number is 1-650-558-7800. Use it for urgent leaks, breaks, outages, or water-system emergencies; the Cal Water leak page also provides an online report form for public leaks and water waste. For a customer-side plumbing leak, shut the house valve when safe and arrange repair promptly.
- Leak-adjustment policy
- Cal Water instructs customers with an unusually high bill to turn off indoor and outdoor water and watch the meter's test hand; movement indicates water is passing through the meter. Customers should check toilets, dripping faucets, irrigation valves and timers, softeners, filters, pools, fire sprinklers, hose fittings, wet spots, and other indoor or outdoor plumbing. Cal Water's leak page states that leaks, breaks, or other water-related malfunctions must be repaired within five business days after Cal Water notification. The reviewed public materials explain investigation and repair expectations but do not publish a guaranteed private-leak credit percentage, minimum historic-use formula, or universal receipt cap for San Carlos. Customers should contact the Bayshore center promptly, retain dated invoices, photographs, meter readings, and plumber reports, and request an account-specific review; meter-error testing and bill adjustment are separate CPUC Rule 18 processes.
- Utility assistance program
- Cal Water's July 2026 Schedule CAP applies across all tariffed service areas. For an eligible individually metered single-family residential customer, the monthly credit equals 50% of the 5/8 x 3/4-inch service charge, prorated for a partial month, with a maximum monthly credit of $48.00. Qualified nonprofit group living, agricultural employee housing, and migrant farmworker housing facilities receive a $20.00 monthly credit per qualifying sub-metered customer. Eligibility is based on household gross income at or below the applicable CARE maximum or qualifying CARE participation; the customer must submit the authorized declaration or proof, may be renewed no more often than annually, and can be re-billed for periods of ineligibility. The CAP surcharge is excluded for CAP customers and is otherwise a separate bill item.
- State and federal aid connection
- San Carlos customers can apply for Cal Water CAP, request an extension of up to two weeks, split a balance through an arrangement of up to six months, or use PromisePay for eligible residential past-due balances. Cal Water's assistance materials also point customers toward local nonprofit organizations and the CPUC complaint/consumer-assistance process. The reviewed current materials do not publish a dedicated LIHWAP application URL or named San Carlos charity for water arrears, so customers should contact Cal Water first and separately check current California, county, city, and nonprofit water-assistance programs; eligibility and payment-plan approval are account-specific.
