You cannot install a new self-regenerating salt water softener in Chino. The Inland Empire Utilities Agency ordinance prohibits it here along with Chino Hills, Fontana, Montclair, Ontario, Rancho Cucamonga and Upland. If someone is quoting you a salt softener for a Chino address, they are quoting something you are not permitted to install.
Existing units are grandfathered, so you do not have to remove one you already have. IEUA pays a rebate if you choose to. And when your current unit fails, you cannot replace it like for like.
Hardness in Chino
Chino is served by City of Chino water utility. We do not publish a hardness figure we have not measured, so we test at your hose bib before we quote.
Can you install a water softener in Chino?
Not a new self-regenerating salt one. The reasoning behind the ordinance is brine discharge: every regeneration cycle sends salt into the wastewater system, and the Chino Basin groundwater underneath the city is where that salt accumulates. Removing it at the treatment end is expensive, so the agency addressed it at the source.
Chino sits directly over the basin the ordinance is designed to protect, which is part of why this city is covered. Existing units installed before the ordinance may keep running.
What we install in Chino instead
A salt-free whole-home water conditioning system, $3,495 installed, equipment and professional installation included. It is not a softener and we will not call it one. It does not remove hardness minerals from the water.
What it does is condition them through template assisted crystallization so they stop forming scale on pipes, water heaters and fixtures, which is the damage you are trying to prevent. It pairs that with whole-home carbon filtration for chlorine taste and odor, uses no salt, needs no drain line and has no regeneration cycle. Maintenance is one inexpensive filter cartridge a year.
How hard is the water in Chino?
The City of Chino runs its own water utility drawing on Chino Basin groundwater alongside imported supply. We do not publish a hardness figure for Chino because we have not measured it consistently across the city, and basin readings vary by well field.
So we test at your hose bib before quoting rather than repeating a number we cannot stand behind.
The Preserve, College Park and the older grid
The Preserve and College Park on the south side are newer master-planned construction built on former dairy land. Main line access in those homes is usually straightforward, and many were roughed in with a treatment loop, though it cannot be used for a salt softener here.
The older grid around downtown Chino is a different building era with a meaningful amount of pre-1970 housing. On those homes we more often find galvanized supply line still in service. Scale protection does not help a pipe already corroding shut, and we will tell you if that is what we find.
The full ordinance, and the rebate
We wrote a longer page on the IEUA ordinance, which cities it covers, how the grandfathering works, and how the removal rebate is claimed.
