The City of Norco reports total hardness from 54 to 290 mg/L, averaging about 132 mg/L, depending on which source is feeding your area. A softener evens out those swings inside the house. Call the number on this page to be connected with a local plumber in Norco.

How the call goes
You are connected with an independent plumber who serves Norco. Tell them what you have noticed, how many people live in the home, and how the property is laid out. On many Norco lots, the water line also feeds corrals, barns and arena watering, and the plumber will want to know which outlets should stay on unsoftened water. Keeping animal and landscape water off the softener saves a lot of salt.
A tap test is common. Because Norco's hardness range is so wide, measuring at your own faucet matters more here than in most towns.
What affects cost
- Which outlets are routed through the softener and which bypass it
- Unit capacity for your hardness and household use
- Pipe runs on larger lots where the main enters far from the house
- Access to a drain and power
- Optional carbon or drinking water filters
- Salt use over time
Norco's water
The City of Norco runs its own water utility, serving about 26,000 people. Most of its water is purchased treated groundwater, largely from the Arlington Desalter, along with water from the Chino Desalter, the City of Riverside and Jurupa Community Services District. The City adds groundwater from its own Chino subbasin wells in southwest Norco and a small amount of treated surface water from the City of Corona.
That blend explains the spread in the City's water quality report: 54 to 290 mg/L, averaging 132.3 mg/L, or roughly 3 to 17 grains per gallon. Desalted water is soft; well water is much harder. Norco disinfects with chlorine rather than chloramine.
Norco is a semi-rural equestrian city, nicknamed Horsetown USA, with corrals and riding trails throughout. The City's Public Works Sewer Division operates the sewer system that receives regeneration water. For permits, Norco Building & Safety is at City Hall on Clark Avenue; the plumber can confirm whether your installation needs one.
Checklist before the visit
- List the outdoor outlets: barn, troughs, arena, irrigation
- Find the main shutoff and confirm it works
- Pick a shaded or indoor spot for the unit
- Note your water heater's age
- Have a recent City of Norco water bill ready
