Filtration and UV Systems
Protect Your Water, Your Family, and Your Health
Clean tank water starts with a clean tank — but long-term safety depends on filtration and UV protection. At Pure Water Systems NZ, we supply and install filtration and UV systems that remove sediment, bacteria, viruses, and chemicals from your stored or mains water.
Whether your property relies on tank water, bore water, or town supply, our tailored systems ensure your water is safe, great-tasting, and free from harmful contaminants.
Why Filtration and UV Systems Matter
Even after a tank clean, water can become contaminated through:
- Dust, pollen, or chemical drift from nearby farmland.
- Animal or insect activity near collection areas.
- Old pipework or sediment in the system.
Our filtration and UV systems provide complete protection by:
- Filtering out dirt, rust, and organic particles.
- Neutralising bacteria, viruses, and pathogens.
- Improving clarity, taste, and smell.
- Safeguarding your family, pets, and livestock from illness.
Our Filtration Systems
Designed to suit every property, our filtration systems remove sediment, chemicals, and metals improving taste and water quality. We provide:
- Countertop and under-sink filters.
- Whole-of-house filtration systems
- Multi-stage reverse osmosis (RO) options.
- Each system can be customised to your water source and flow rate.
UV Sterilisation Systems
Our PWS Protect-UV System disinfects water using ultraviolet light with the same natural wavelength found in sunlight which destroys microorganisms without chemicals.
- How it works:
- Water passes through a stainless-steel chamber where it’s exposed to a high dose of UV light.
- The UV light inactivates bacteria, viruses, algae, and parasites instantly.
- No chemicals, no taste or odour, no by-products.
- Why choose UV sterilisation:
- Destroys 99.99% of bacteria, viruses, and parasites.
- Immediate treatment, no holding tanks required.
- Environmentally friendly, chlorine-free process.
- Low maintenance (UV lamp replaced annually).
- Approved to New Zealand standards.

What is UV Sterilisation and How Does It Work?
Ultraviolet (UV) sterilisation is a chemical-free, eco-friendly way to disinfect water. It uses high-intensity UV light which is part of the natural spectrum of sunlight to destroy bacteria, viruses, algae, and other microorganisms by disrupting their DNA, preventing them from reproducing.
- Sediment Filtration – Removes dirt, rust, and organic particles.
- UV Chamber – Exposes filtered water to UV light (254 nm), instantly neutralising microorganisms.
- Pure Water Supply – Delivers safe, clean water throughout your home or business — without chemicals or chlorine.
Key Benefits
- Kills 99.99% of microorganisms (E. coli, Giardia, Cryptosporidium)
- Chemical-free, safe, and environmentally friendly
- No taste or odour added to your water
- Low maintenance & cost-effective operation
- Pure Water Systems – Clean. Safe. Reliable. Pure.
Why is Pre-Filtration Important in the UV Sterilisation Process?
Pre-filtration is essential for your UV system to perform effectively. It reduces turbidity the cloudiness caused by particles like sand, dirt, and sediment and allowing UV light to reach and destroy microorganisms efficiently. Without it, larger particles can shield bacteria, cysts, and viruses from UV exposure, reducing disinfection performance.
- Viruses are 10–100 times smaller than bacteria.
- Even fine sediment can protect them unless water is filtered first.
The Pure Water Systems Advantage
- All our UV systems include multi-stage pre-filtration, removing suspended solids before sterilisation and ensuring maximum UV efficiency and delivering truly safe, pure water throughout your property.
