If you have a plumbing emergency in Norco, close the main shutoff, and if you smell gas, leave and call 911 and SoCalGas at 1-800-427-2200. The City of Norco runs both the water and sewer systems. For leaks, backups and broken equipment on your property, call the number on this page to be connected with a local plumber in Norco.

When you make the call
You will be connected with an independent plumber who serves Norco. Give the address and explain what failed, whether water is still running and whether the main is closed. On a larger lot, say where the problem is: in the house, in a barn or tack room, or along a line running out to troughs or corrals. Ask how after-hours pricing works first. Arrival time depends on the hour and workload and is not promised.
What affects the price
- Time. After-hours, weekend and holiday visits usually cost more.
- Length of the run. Long buried lines to outbuildings take more time to locate and expose.
- Repair type. A cracked fitting is quick; a new water heater or a sewer repair is bigger.
- Permits. City of Norco Building & Safety, reached through City Hall at (951) 735-3900, handles plumbing and water heater permits.
Norco's setup
Norco calls itself Horsetown USA. It is a semi-rural equestrian city where corrals, ranches and riding trails take the place of most sidewalks, and many properties carry water lines well beyond the house. Those outdoor lines, frost-free hydrants and hose connections are frequent trouble spots, especially when hooves or equipment damage a shallow pipe.
The City of Norco runs its own water utility, serving about 26,000 people through roughly 7,500 connections. Utility billing and customer service is (951) 270-5654, and the Public Works Superintendent is (951) 270-5605. Most of the water is purchased desalted groundwater, largely from the Arlington Desalter, blended with water from the City's own wells and disinfected with chlorine. Hardness ranges from 54 to 290 mg/L and averages about 132 mg/L, moderately hard to hard depending on the source.
Sewer is also a City service, run by the Public Works Department's Sewer Division. If your neighbors are backing up too, call the City; a backup in your house alone usually means your own lateral or a drain inside.
Before help arrives
- Shut the main, or the valve to the outbuilding line if it has one
- Keep animals away from flooded areas and wet electrical equipment
- Turn off a leaking heater at the gas valve or breaker
- Open the gate and note where the line runs
