Fontana, California

Fontana Municipal Code § 23.162 (Ordinance No. 1656, adopted March 27, 2012) makes it unlawful to install, replace, or enlarge a residential self-regenerating water softening appliance that discharges regenerated wastes to the city’s community sewer. That is a city sewer rule implementing IEUA Ordinance § 2.6 — not a statewide ban. A 2024/2025 Fontana Water Company CCR PDF did not open; this file does not invent hardness.

This city’s report did not print a number we can put on the chart. Open the current water-quality report. We do not invent a value.

Brine / salt to the sewer
Self-regenerating salt softeners prohibited (district rule). Fontana Ordinance No. 1656 (introduced March 13, 2012; adopted March 27, 2012) amended Chapter 23, Article II, Division 5, § 23.162. It is unlawful to install or cause to be installed, replace, or enlarge any residential self-regenerating water softening appliance used for softening all or any part of the water supply to any premises when the appliance is regenerated by on-site application of a salt-containing brine solution with the regenerated wastes discharged to the city’s community sewer system. The section does not apply to a portable-exchange water softener regenerated off-site at a lawfully regulated location. IEUA Ordinance § 2.6 states the same regional restriction. That is a Fontana / IEUA sewer rule — not a statewide ban. Ask Public Works or the agency on the sewer bill about the address.

Extra context besides the utility report and the chart above — geology, an unregulated table, or a published study. Not a second set of printed tap numbers.

Fontana’s sewer rule is a city ordinance implementing an IEUA regional restriction, not a statewide salt-softener ban. Ordinance No. 1656, adopted March 27, 2012, amended Chapter 23, Article II, Division 5, § 23.162: it is unlawful to install or cause to be installed, replace, or enlarge any residential self-regenerating water softening appliance used for softening all or any part of the water supply to any premises when the appliance is regenerated by the on-site application of a salt-containing brine solution with the regenerated wastes discharged to the city’s community sewer system. The section does not apply to a portable-exchange water softener regenerated off-site at a lawfully regulated location. Findings cite Water Code § 13148, Regional Board Resolution No. R8-2004-0001, and Order No. R8-2010-0008. IEUA Ordinance § 2.6 states the same regional restriction. Ask Public Works or the agency on the sewer bill about the address.

Drinking water in most of Fontana is Fontana Water Company (San Gabriel Valley Water Company — Fontana system), not a city-owned utility. A 2024 or 2025 Consumer Confidence Report PDF did not open from the URLs we tried. This file does not invent hardness, disinfectant residual, or a contaminant bar from a ranking site. Open the current Fontana Water Company report. Kitchen shopping stays the Cloud RO / Waterdrop path already used on other cities if a listing is why you are looking.

What actually fits

Some links are affiliate links. If you buy through one, we may earn a commission. That does not change the match, and it is not a medical claim.

If a dealer is selling hardness equipment

A single tall tank with no brine tank, installed in a laundry alcove next to a washing machine.
Salt-free conditioner: one tank, no salt bin.

Open the current CCR for grains. This file does not invent a number from a ranking site. A salt softener needs a drain if it is legal at the address.

If the water tastes like the plant’s disinfectant

A single black whole-house carbon tank with a control head, installed in a garage and connected to copper pipe.
Whole-house carbon tank. No brine tank.

Open the CCR for chlorine vs chloramine, then match that claim. A 42 chlorine listing is not chloramine.

If you are shopping a PFAS listing for the kitchen

Under-sink reverse osmosis system with a white storage tank, filter canisters, and colored tubing in a kitchen cabinet.
Under-sink reverse osmosis: filters, tank, and a second faucet.

The under-sink RO we actually run is Cloud RO — NSF/ANSI 58, kitchen tap, not a whole-house tank. Check the exact listing if PFAS is why you are shopping. Waterdrop is a tankless option if you want that path. A certifier-listed pitcher is the cheap first step. Nobody is paying for a medical claim.

If you have not tested the tap

A homeowner kit is a start. It is not a state-certified lab. Use a certified lab when the decision is expensive.
