San Francisco residents and businesses can report water leaks, broken mains, and hydrant problems to SFPUC 24/7. Customer-side leaks must be repaired promptly, and SFPUC offers leak-adjustment credits for documented bills.
SFPUC operates a 24-hour Water Quality and Distribution Emergency line at (415) 551-3000 for leaks, low pressure, and main breaks on the Hetch Hetchy regional system or local distribution mains. Customers must repair private-side leaks (downstream of the meter) within a reasonable period, typically 30 days after notice, or face shut-off. The agency offers a one-time leak adjustment credit when a customer documents repair of a hidden leak with plumber receipts. Hydrant tampering is a separate violation enforced by SFFD and SFPUC police.
Unrepaired private leaks risk service shut-off and full billing for wasted water. Hydrant tampering or unauthorized hookups can result in $1,000+ fines and criminal referral.
