Roof catchment looks clean — but bird and possum droppings introduce E. coli into the water that ends up in your tank. Tank sediment builds up over time. Most healthy adults are fine; the real risks are for kids, pregnant women, and anyone immunocompromised.

UV sterilisation kills the microbiology. Multistage filtration handles the sediment, taste, and chlorine if you ever switch to mains. Together they make tank water safe to drink straight from the tap — without bottled water, without boiling, without crossing your fingers.

If you’re not sure what’s in your tank water, we’ll come out and look at your setup. Free assessment, honest recommendation.
