Ultra Violet (UV) Water Treatment

Safe, chemical-free disinfection for homes, schools, businesses and industry. UV systems neutralise harmful microorganisms at the rated flow, providing immediate protection without affecting taste.

Why UV?

  • Proven protection – reduces bacteria and viruses by up to 99.9% (at the rated flow).
  • Immediate & economical – disinfection happens instantly and uses less energy than a typical household light bulb.
  • Low maintenance – simple system with visual/audible lamp-failure alarms.
  • No chemicals, no taste change – a natural process that retains beneficial minerals.
  • Flexible install – available pre-assembled for easy installation or as components.

UV is widely used across domestic tank water and by councils, schools, and the dairy, food and brewing sectors to keep water safe.

Where UV fits

  • Whole-home (tank/bore)
  • Point-of-use (kitchen drinking line)
  • Commercial & community (amenities, small plants)
  • Food & beverage (process and rinse water)

How we work

  1. Water & site check – flow, plumbing layout, and water clarity.
  2. System selection – UV size & pretreatment (if needed) to match your rated flow.
  3. Install & commission – we set up, test and show you how to monitor alarms.
  4. Care & reminders – simple maintenance plan and annual check-in.

Maintenance at a glance

  • Lamp – replace on schedule (typically annually, usage dependent).
  • Quartz sleeve – wipe/clean when flow or clarity drops.
  • Prefiltration – recommended where water carries sediment/colour to keep UV working at its rated performance.

(We’ll recommend a maintenance schedule for your water and usage.)

FAQ

Does UV change water taste?

No—disinfection is physical, not chemical, so taste and beneficial minerals are unaffected.

Will it kill viruses and bacteria?

Yes—up to 99.9% reduction at the rated flow for properly sized systems.

Do I need pretreatment?

If your water has visible sediment/colour, a simple pre-filter helps ensure full UV dose at your flow rate.

Can you supply pre-assembled systems?

Yes—pre-built or component-only options are available.

Can you design iron removal for my bore?

Yes—we build custom systems to suit your water.
