In San Bernardino, close the main shutoff for any major leak, and for a gas smell, leave and call 911 and SoCalGas at 1-800-427-2200. The Municipal Water Department takes water and sewer emergencies at 909-384-5141, but the service line past the meter and the sewer lateral belong to the owner. For those, call the number on this page to be connected with a local plumber in San Bernardino.

Warning signs
- A leak spraying or pouring from a supply line, valve or water heater
- Sewage coming up through a tub, shower or cleanout
- Water bubbling up in the yard between the meter and the house
- A sudden loss of pressure everywhere in the house
- Gas odor near an appliance (leave the house, then call 911 and SoCalGas)
Minor drips and slow drains can wait for a regular appointment. Active water and sewage cannot.
Who owns what in San Bernardino
The San Bernardino Municipal Water Department (SBMWD) supplies water to most of the city and also collects and treats its wastewater. SBMWD shares the Bunker Hill Basin with more than 20 other suppliers, so some city addresses may be served by another agency; its service area map shows which. SBMWD maintains the pipe from the main up to the meter, and the customer is responsible for the underground line from the meter to the house and everything past it. On the sewer side, the city maintains the main in the street and the property owner maintains the lateral. For a break in the street or a main backup, SBMWD's water and sewer emergency number is 909-384-5141, answered by a service after hours.
The water here is all local groundwater, disinfected with chlorine, and hard: the 2025 report lists an average of 242.2 mg/L. Scale shortens water heater life and can seize valves that have not been turned in years. In ZIP 92404, about 72 percent of homes were built before 1980, so older laterals and supply lines are common in parts of the city.
What affects the bill
- Hour of the call. Late night, weekend and holiday work normally costs more.
- Which side of the meter. Work on the owner's line or lateral is billed by the plumber; SBMWD handles its own pipe.
- Digging. A failed lateral or yard line can require excavation.
- Permits. The City of San Bernardino Building & Safety Division requires permits for plumbing work; water heater replacements are usually issued over the counter.
