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
- 415-945-1500 for water emergencies such as a possible main break; customer billing support is 415-945-1400.
- Leak-adjustment policy
- Marin Water requires the account holder or authorized representative to submit a complete written application with proof of corrective action and proof of repair. The customer must correct the leak within 48 hours of discovery or notification of high consumption and submit the signed request and documentation within 30 days of the bill date for the affected period; incomplete applications are denied and require reapplication. Adjustments are limited to two billing periods and one adjustment every 36 months, with additional insurance documentation required for claims exceeding $5,000. Faucet leaks are excluded; the district reviews the eligible amount under Code Section 6.01.090 rather than applying a simple advertised percentage.
- Utility assistance program
- Marin Water offers an income-based Service Charge Waiver for qualifying single-family customers, waiving the bi-monthly base water charge, Capital Maintenance Fee, and Watershed Management Fee; the program uses a gross-income threshold at or below 80% of Marin County’s HUD low-income median, conservation-device requirements, and a verification visit. Eligible customers are also exempted from Tier Four for four years. A Super Saver discount of up to $8 is automatically applied to approximately the lowest five percent of single-family users, and medical-disability discounts are available.
- State and federal aid connection
- Marin Water’s assistance is administered locally through its income-waiver, medical-disability, and payment-arrangement programs. The reviewed district pages do not identify a dedicated state or federal water-assistance application; customers needing broader aid are directed to contact Customer Service at 415-945-1400 and discuss a deferred or amortized arrangement.
