The City of Norco runs its own water utility, mostly purchased desalted groundwater blended with water from City wells, and its Public Works Sewer Division maintains the sewer system. Plumbing permits come from Norco Building & Safety at City Hall. Call the number on this page to be connected with a local plumber in Norco.
What happens when you call
You'll be connected with an independent local plumber who handles commercial work in Norco, from shops near the I-15 to properties built around the city's horse-keeping character. Expect questions about the building, the fixtures or lines involved, any outdoor water service for stalls, arenas or wash areas, and when the water can be shut off. If more than one structure on the lot is affected, say so, since it changes how the plumber plans the visit.
What affects the cost
- Long outdoor runs to barns, arenas or wash racks
- Locating time for a buried leak or a blockage
- Equipment such as commercial water heaters or water treatment
- Scheduling around business hours
- Permits and inspection
Norco's water and sewer
The City's water system serves about 26,000 people through roughly 7,500 connections. Most of the supply is purchased, treated groundwater from the Arlington Desalter, the Chino Desalter, the City of Riverside and Jurupa Community Services District, blended with groundwater from the City's own Chino subbasin wells in southwest Norco and a small amount of treated surface water from Corona. Norco disinfects with chlorine rather than chloramine. Its 2024 report lists total hardness from 54 to 290 mg/L, averaging about 132, so the scale a building sees depends on the blend reaching it.
The Public Works Department's Sewer Division maintains the City's Sewer System Management Plan. The City's sewer page doesn't describe treatment or where private laterals end, so confirm with Public Works before work at the connection. For billing and service questions, Norco Utility Billing is at (951) 270-5654, and the Public Works Superintendent is at (951) 270-5605.
Norco calls itself Horsetown USA, with corrals, ranches and riding trails in place of most sidewalks, so many properties have hose bibbs, troughs and long irrigation runs. Those outdoor connections are exactly the kind of cross-connection risk backflow devices exist for; ask Public Works whether a property needs one. Permits are issued by Norco Building & Safety at City Hall, 2870 Clark Avenue, (951) 735-3900.
Before the plumber arrives
