What is tank water sterilisation?

Many different products have been used to treat drinking water over the years. But no treatment has been perfect... until now!


At RAINMAN®, we exclusively use KIWIOXIDE® (solid ClO2) – because its now proven to be the safest, easiest, and most effective way to completely sterilise your rainwater system.


KIWIOXIDE® destroys:

  • 100% bacteria (eg. E. coli), viruses, moulds, fungi, and parasites (eg. Giardia & Cryptosporidium)
  • Eats all algae and biofilm (slimy layers inside your tank, pump, and pipework)

These contaminants affect water health, taste, and even flow thru your supply system.


Unlike other water treatment options, KIWIOXIDE®:

  • Non-toxic: Does not create harmful byproducts & compounds
  • Tasteless & Odourless: Does not leave any chemical taste or smell
  • Shock Treatment: Does its job – and then breaks down quickly, leaving no residue
  • Eco-friendly: Is non-corrosive, biodegradable, and completely safe for humans & (non-aquatic) animal life to drink.


We simply treat your tank water and over the following 12-24 hours your entire rainwater system is sterilised – including your pipework, hot water cylinder, and kitchen appliances – all the way from the tank to the tap!

  • FAQ: What does tank sterilisation actually do?

    It kills bugs, bacteria, viruses, parasites, algae, and biofilm. It also improves the taste and smell of your tank water without leaving any chemical residue.

  • FAQ: Is sterilised tank water safe to drink?

    Yes. Our active ingredient is used globally in food and water treatment.


    Once the treatment is complete (after 12–24 hours), your water is clean, safe, fresh, and great-tasting!

  • FAQ: What treatment do you use to sterilise my tank?

    We use our own product, KIWIOXIDE®, powered by Chlorine Dioxide.


    It works fast, kills more bugs than other treatments, and leaves no bad taste or harmful by-products.


    It’s safe for household use, animals, and gardens — but not for use in aquariums or ponds — it’s obviously harmful to all forms of aquatic life!

  • FAQ: How often should I sterilise my tank?

    Every 3–6 months is ideal.


    If you’ve had heavy rain, drought, bad smells, or sickness in the house, it’s smart to treat your tank straight away. Think of it like a health check-up for your water supply!

  • FAQ: Can you sterilise my tank without cleaning it?

    Yes — especially if the tank looks relatively clean.


    But if there is visible sludge or sediment, a proper water tank clean followed by tank sterilisation gives the best results.

  • FAQ: Does tank sterilisation remove sludge?

    No. It kills protozoa and eats biofilm — but does NOT remove solid build-up. That’s when you need a full tank clean!

  • FAQ: How long does tank sterilisation take?

    It starts working immediately.


    If you don’t have a carbon filtration system, we recommend waiting 12–24 hours before using the water for drinking or cooking.
