Upland, California

Inland Empire Utilities Agency Ordinance § 2.6 prohibits installing, replacing, or enlarging a self-regenerating water softening appliance that discharges to a community sewer tributary to the IEUA regional sewerage system. Upland is an IEUA contracting agency. That is an IEUA regional sewer/POTW rule — not a statewide ban. The 2025 CCR prints hardness 120 ppm (range ND–340).

Cited numbers from the utility report. Length follows the printed value against a labeled scale — not a health ranking. If the report has no number, it is not on the chart.

Hardness120 ppm (range ND–340)
TTHMs44.9 ppb (range ND–77.0)
HAA514.6 ppb (range ND–28.0)

Portable-exchange softening — not a brine tank

A self-regenerating salt softener that drains to the sewer is prohibited here.

Portable-exchange tanks, if that exception applies at your address. The resin still removes hardness. The salt work happens off site. Do not install a self-regenerating unit to the sewer here.

Other options that still fit

Salt-free conditioner
A salt-free conditioner changes how scale sticks. It does not soften. Soap and spots stay closer to untreated. No brine line.

Whole-house carbon — match chlorine vs chloramine
Open the CCR for chlorine vs chloramine, then match that claim. A 42 chlorine listing is not chloramine.
Shop whole-house carbon Shop catalytic carbon for chloramine
Under-sink reverse osmosis
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. Shop Amazon first for under-sink RO, or buy Cloud direct. 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.

Water utility: City of Upland Water Utilities
Hardness: Hardness, total as CaCO3, 120 ppm (range ND–340) on the 2025 unregulated table. One printed row, not a groundwater / surface / imported blend we invented. — City of Upland 2025 Consumer Confidence Report
Disinfectant: A chlorine or chloramine residual number is not on the regulated table we opened. Chlorate 32.3 ppb (range ND–250) is printed as a disinfection by-product. Open the current report for the residual. This file does not invent it. — City of Upland 2025 Consumer Confidence Report
Sanitation district: Inland Empire Utilities Agency (Upland is a contracting agency)
Brine / salt to the sewer: Self-regenerating salt softeners prohibited (district rule). IEUA Ordinance § 2.6 says the installation, replacement, or enlargement of any self-regenerating water softening appliance which discharges into the Community Sewer System that is tributary to the Regional Sewerage System shall not be allowed. Each contracting agency shall adopt a local ordinance to implement the restriction. The section does not apply to a portable-exchange water softener regenerated off-site at a lawfully regulated location. IEUA may offer a voluntary rebate for removal of an operational unit. The City of Upland is an IEUA contracting agency. That is an IEUA regional sewer/POTW rule — not a statewide ban. Ask Upland 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.

MicroplasticsWHO’s 2019 review examined studies that found microplastic particles in treated tap and bottled water in many places. That is a published-occurrence finding, not a number from this city’s water-quality report, and we do not invent a particles-per-liter count for the tap.Microplastics in drinking-water — World Health Organization

Upland’s sewer rule is an Inland Empire Utilities Agency regional ordinance, not a statewide salt-softener ban. IEUA Ordinance § 2.6: the installation, replacement, or enlargement of any self-regenerating water softening appliance which discharges into the Community Sewer System that is tributary to the Regional Sewerage System shall not be allowed. Each contracting agency shall adopt a local ordinance. The section does not apply to a portable-exchange water softener regenerated off-site at a lawfully regulated location. IEUA may offer a voluntary rebate for removal of an operational unit. The City of Upland is an IEUA contracting agency. The City of Upland is not IEUA if the address is on another sewer. Ask Public Works or the agency on the sewer bill about the address.

Drinking water in 2025 was about 80 percent groundwater, 3 percent San Antonio Canyon surface water, and 16 percent imported water treated at the Water Facilities Authority Agua de Lejos plant. The 2025 Consumer Confidence Report prints hardness, total as CaCO3, 120 ppm (range ND–340) as one unregulated row. We do not invent a three-source blend.

TTHMs 44.9 ppb (range ND–77.0). HAA5 14.6 ppb (range ND–28.0). Nitrate 4.7 ppm (range 0.1–6.0), MCL 10. A chlorine or chloramine residual number is not on the regulated table we opened. This file does not invent one. Kitchen shopping stays the Cloud RO / Waterdrop path already used on other cities if a listing is why you are looking.
