1. UV is now expected to be validated and full-flow
§4.2.2.1: UV "should be validated and designed for full flow (not side stream)", at least 3-log Cryptosporidium reduction on interactive features and 2-log elsewhere, positioned before the chlorine dosing point. A side-stream unit, or one with only the manufacturer's test report behind it, does not meet that sentence.
2. A validated system buys you out of the Crypto shutdown
§9.2: after a Cryptosporidium notification, hyperchlorination at 20 mg/L for 13 hours or 10 mg/L for 26 hours — unless a validated system such as UV is installed. For a swim school or program pool that is the clause that pays for the equipment.
3. Records are a monthly habit, not an annual scramble
§3.1.2.4 asks for controller logs to be downloaded monthly; §6.1.2 for probes to be calibrated per the manufacturer; Regulation 2022 Schedule 1 cl 11 for six months of records. Together they mean the controller needs an output and someone needs a calendar.
4. The operator is expected to be trained
Chapter 10 recommends the Aquatic Technical Operator skill set (SISSS00131). Royal Life Saving NSW runs it; it is twelve months, online with practical units.
Three checks to do this month
- Open the controller: does it display free chlorine, or only ORP? If only ORP, it predates the 2022 Regulation's test.
- Find the UV unit's validation certificate. If there is a manufacturer's report but no NSF/ANSI 50 listing or UVDGM bioassay, note it.
- Find last month's log download. If there isn't one, the §3.1.2.4 habit has not started.
