    A storage-age scenario, not a treatment failure.

    The treatment outlet stays fresh. A five-day hold lowers the example tank residual from 1.02 to about 0.43 mg/L. Amber indicates lower residual, not confirmed contamination. Tank mixing, travel time and junction blending shape the downstream readings.

    Illustrative controls alarm below 0.65 mg/L and clear above 0.78 mg/L after confirmation. Assigned upstream alarms can open downstream flushing valves before affected water arrives. Flushing changes flow, but does not isolate customers or guarantee that no aged water reaches them.

    Fictional LA-inspired network; simplified linear-resistance hydraulics and complete-mix storage, not LADWP data or operational settings. Water age is modeled; ORP is an illustrative proxy. Field use requires site-specific hydraulics, pressure checks, discharge controls and engineered safeguards. Water-quality modeling context.
