Buellton, California

Buellton Municipal Code Title 14, Chapter 14.28 restricts discharge from water conditioning and water softening equipment into the city sewage system (1993). That is a city sewer rule authorized against Central Coast Regional Board mineral-constituent limits — not a statewide ban. The 2025 CCR (2024 data) prints hardness as three labeled columns, not a citywide blend.

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.

Hardness (CCWA PPWTP)88 ppm (range 35–148)
Hardness (State Water)88 ppm (range 32–146)
Hardness (groundwater)433 ppm (range 420–460)
Total chlorine (CCWA)2.85 ppm (range 0.18–3.84)
Total chlorine (groundwater)1.43 ppm (range 0.12–2.20)

On the report

Water utility: City of Buellton Public Works
Hardness: Treated CCWA PPWTP 88 ppm (range 35–148). State Water 88 ppm (range 32–146). Groundwater 433 ppm (range 420–460). Those are three labeled columns, not a blended citywide number. 2025 CCR covering 2024. — City of Buellton 2025 Consumer Confidence Report (2024 period)
Disinfectant: Total chlorine residual. Treated CCWA PPWTP 2.85 ppm (range 0.18–3.84). Groundwater 1.43 ppm (range 0.12–2.20). State Water column NA. 2025 CCR (2024 data). — City of Buellton 2025 Consumer Confidence Report (2024 period)
Sanitation district: City of Buellton (sewer)
Brine / salt to the sewer: Self-regenerating salt softeners prohibited (district rule). Title 14, Chapter 14.28 Discharge from Water Conditioning and/or Water Softening Equipment says no person shall allow water conditioning or softening equipment of any type to discharge its wastes into the city sewage system except as expressly provided in that chapter. The city’s August 2024 insert says the 1993 ordinance was adopted to meet Central Coast Regional Board mineral-constituent limits, and that homes using rock salt, potassium chloride, or reverse-osmosis brine to the sewer must update to a system that does not discharge salts/chlorides. The insert names portable-exchange tank systems as an approved option. That is a City of Buellton 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.

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

Buellton’s rule is a city sewer ordinance, not a statewide salt-softener ban. Title 14, Chapter 14.28 Discharge from Water Conditioning and/or Water Softening Equipment: no person shall allow, permit, or cause any water conditioning or softening equipment of any type to discharge its wastes into the city sewage system except as expressly provided in that chapter. Findings cite Central Coast Regional Board discharge requirements for mineral constituents. The city’s August 2024 insert says the restriction was adopted in 1993, and that if a home uses rock salt, potassium chloride, or reverse-osmosis brine to the sewer, the city requires an update to a system that does not discharge salts/chlorides. The insert names portable-exchange tank systems as an approved option. Ask Public Works or the agency on the sewer bill about the address. We do not invent another exception.

Drinking water in 2024 came from four groundwater wells (Buellton Uplands and Santa Ynez River Underflow) plus State Water Project water. The 2025 Consumer Confidence Report (2024 period, printed June 2025) prints hardness as three labeled columns — treated CCWA PPWTP 88 ppm (range 35–148), State Water 88 ppm (range 32–146), and groundwater 433 ppm (range 420–460). We do not invent a citywide blend.

Total chlorine residual: CCWA 2.85 ppm (range 0.18–3.84); groundwater 1.43 ppm (range 0.12–2.20); State Water NA on that row. 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 you want actual soft water

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.

If you only want less scale and you hate salt bags

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.

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

Shop salt-free conditioners

If the shower just smells like the pool

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.

That is chlorine. A whole-house carbon filter with an NSF/ANSI 42 chlorine claim is the usual match. A softener will not take chlorine out.

Shop whole-house carbon

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.
