The Hallett Validated Potable UV Water Treatment System range provides commercial-grade, drinking-water-compliant UV disinfection for New Zealand properties. Certified to NSF 55 Class A standards, these systems deliver guaranteed 99.99% pathogen destruction with automatic safety shut-off valves—meeting the strict legal requirements of the New Zealand Water Services Act.
MANDATORY LEGAL COMPLIANCE FOR PUBLIC WATER SUPPLIES: Under New Zealand’s Drinking Water Legislation (Taumata Arowai / Water Services Act), validated UV treatment systems featuring automatic safety shut-off valves are a legal requirement for all public and communal water supplies drawn from roof collection or bore sources. This applies directly to schools, marae, sports centres, community halls, commercial kitchens, and public venues.
Hallett Validated systems are engineered in North America specifically to satisfy these strict regulatory mandates. Unlike standard unvalidated UV units, Hallett systems use patented Crossfire Technology with dual high-output lamps and elliptical reflectors to eliminate shadow zones, monitor water transmittance (UVT) in real time, and automatically wipe quartz sleeves to prevent mineral scaling.
Conventional single-lamp UV systems send water down a stainless-steel pipe around a central bulb, leaving shadowed zones whenever water clarity drops or minerals build up on the quartz sleeve.
UV Pure's patented Crossfire Technology™ completely re-engineers this process. By mounting two high-output UV lamps outside the water stream and surrounding them with precision elliptical reflectors, light energy is redirected through the quartz chamber from 360 degrees.
This intense multi-directional light path eliminates shadowing, targets harmful pathogens from every angle, and ensures reliable sterilization even in low UV Transmittance (UVT) conditions. Paired with dual smart UV sensors that continuously monitor lamp output and water quality, Crossfire Technology practically eliminates nuisance alarms while providing uncompromising water safety.
Dual lamps & elliptical reflectors fire UV light through the quartz chamber from every angle.

Hallett Validated systems provide verified compliance documentation needed for council water safety plans and Taumata Arowai audits across New Zealand. Download official brochures and engineering manuals below:
Pre-Filtration Requirements: To ensure optimal UV light penetration and maintain validated performance, water entering any Hallett UV system must be pre-filtered to remove suspended sediment and organic particulate. We recommend pairing your Hallett unit with our 20" Pleated 2-Micron and 20" Polyspun 1-Micron Filtration System.
Yes, if your facility serves the public, staff, or community members. Under the NZ Water Services Act (regulated by Taumata Arowai), non-household drinking water supplies—including schools, marae, sports centres, community halls, cafes, and commercial premises supplying bore or roof water—are legally obligated to use an independently validated UV treatment system (such as NSF 55 Class A) equipped with an automatic shut-off safety valve.
For a standard single-family residential house on roof or bore water, a validated system is generally not legally mandatory under current Taumata Arowai regulations. However, many homeowners choose a Hallett Validated system for ultimate peace of mind because of its automatic safety shut-off valve (which guarantees untreated water can never reach household taps) and its self-cleaning quartz wiper mechanism. Note: If you run a commercial business from home (such as a registered B&B, commercial kitchen, home day-care, or farm homestay open to the public), a validated system may be required by your local council.
An integrated solenoid safety valve automatically closes if power drops out, a UV lamp fails, or if water transmittance falls below safe levels. This guarantees that unsterilised water can never accidentally pass through to public drinking taps, satisfying key council audit requirements.
Hallett UV lamps are rated for approximately 9,000 hours of continuous operation (roughly 12 months). The onboard digital touchscreen tracks remaining operational hours and alerts caretakers or site managers when replacement lamps are required.
