NSW Health Guidelines, August 2026
Guidelines for Managing Water Quality in Public Swimming Pools and Spa Pools, 12 August 2026 (SHPN (EH) 260089). Guidelines are "should", not law — but they are what an inspector and a consultant read.
| Section | What it says |
|---|---|
| §4.2.2.1 | UV "should be validated and designed for full flow (not side stream)"; at least 3-log Cryptosporidium reduction on interactive water features, 2-log on all other pools; positioned before any chlorine or bromine dosing point |
| §9.2 | After a Cryptosporidium notification: hyperchlorination at 20 mg/L for 13 hours or 10 mg/L for 26 hours (C.t 15,300 mg·min/L) — unless a validated system, "for example, UV", is installed |
| §4.1 | Filtrate turbidity below 0.2 NTU |
| §6.1.2 | Probes calibrated per the manufacturer |
| §3.1.2.4 | Controller logs downloaded monthly |
| §6.3.1 | Microbiological sampling by a NATA-accredited laboratory |
| Ch 10 | Aquatic Technical Operator skill set SISSS00131 recommended for operators |
What stays true
UV is "should"; dosing, residuals, testing and records are law (Regulation 2022). Free-chlorine minima do not drop when UV is installed. The benefits a validated UV system brings are lower combined chlorine, better air, fewer closures and the §9.2 exemption.
What the Guidelines do not prescribe
No dose, lamp type or validation protocol is named. PWTAG Technical Note 31 (revised June 2025) is the reference most consultants use to fill that gap: full flow, design UVT no greater than 94%, medium pressure for chloramine control, validation to NSF/ANSI 50.
