One water source, two needs: clean water and drinking water.

The requirement
“Our well water is cloudy and smells. We need clean water and also water that can be used safely for daily drinking.”
ARS solution
ARS HPFS 150 LPH Auto treats the household clean-water supply, followed by ARS DWB 150 LPH under-sink treatment at the drinking-water point of use.
Verification result
Internal report 27/ARS-01/IV/2026 concludes that the well-water sample did not meet the report’s benchmark, the HPFS output met its clean-water benchmark, and the DWB output met its drinking-water benchmark for the parameters tested.
Measured evidence
The change, shown parameter by parameter.
The summary below reproduces selected values from the ARS internal test report. Values must be read with the sampling date, method, and water context.

Scope note: this internal test applies only to the submitted samples and the parameters measured on the stated date. Water quality may change. Visual clarity alone does not establish drinking-water safety; microbiological and other relevant parameters require verification according to the intended use and applicable requirements.
Sustaining performance
Installation is the start—not the finish.
ARS uses the initial test as a performance baseline. Follow-up service can then be planned around source-water changes, usage load, pressure and flow, equipment condition, operating records, and repeat testing when required.
- 01Record operating conditions and the initial result.
- 02Perform routine inspection, cleaning, backwash, or component service as applicable.
- 03Re-test relevant parameters when conditions, risks, or intended use require it.
ARS case-study standard
Problem → measurement → design → verification → care.
Future projects will follow the same structure so readers can distinguish photographs, measured evidence, technical interpretation, and the plan for sustaining performance.
