PRO Insight: Ontario’s water commonly falls within the hard to very hard range at approximately 180 to 300 mg/L as calcium carbonate due to mineral-rich groundwater from the Chino Basin. The high calcium and magnesium content causes faster scale accumulation in water heaters, pipes, and appliances, reducing efficiency and increasing maintenance costs. Serving Ontario Ranch, Creekside, South Ontario, Downtown Ontario, New Model Colony.

Hard water contains elevated levels of calcium and magnesium minerals that accumulate inside pipes, water heaters, dishwashers, and washing machines over time. In Ontario, local water hardness levels are among the highest in California — making water softener installation one of the most impactful plumbing upgrades available to homeowners in San Bernardino. A licensed plumber can assess your current water conditions, recommend the right system for your home size and usage, and complete the installation correctly from day one.
Ontario’s water is supplied by the City of Ontario Utilities Department using a combination of local groundwater from the Chino Groundwater Basin and imported water from the Metropolitan Water District of Southern California. Groundwater in the region contains elevated calcium and magnesium levels, and finished water commonly measures between 180 and 300 mg/L as calcium carbonate, placing it in the hard to very hard range. These mineral levels accelerate scale buildup inside water heaters, plumbing lines, fixtures, and household appliances throughout Ontario and San Bernardino County.
Tip: If your water heater is less than 10 years old but already showing reduced efficiency or sediment buildup, hard water scale is the most likely cause. A water softener installed upstream of the water heater can extend its service life by years.

Once water hardness is assessed, a licensed plumber will recommend the right system based on your household size, water usage, and plumbing configuration. There are three primary water softener types used in residential installations:
The most effective and widely installed system. Salt-based softeners remove calcium and magnesium ions from the water supply by exchanging them with sodium ions through a resin bed. The resin regenerates automatically using a salt brine solution. Best for homes with severe hard water problems and high daily water usage. Learn more about water heater repair and maintenance that benefits from softened water.
Salt-free conditioners do not remove hardness minerals but change their structure so they cannot adhere to pipe walls or fixture surfaces. Lower maintenance than salt-based systems — no salt to add, no brine discharge. A good option for homeowners on low-sodium diets or in municipalities with salt discharge restrictions. A plumber can advise whether a conditioner or a true softener is appropriate for your Ontario water conditions.
For larger households or properties with continuous high-volume water demand, dual-tank systems provide uninterrupted softened water by alternating between two resin tanks during regeneration cycles. One tank remains in service while the other regenerates — eliminating the period of unsoftened water that single-tank systems produce during overnight regeneration.
