Five things that make water feel different
Every reading rolls up into one of five everyday qualities. Open the map to see which towns lead — and which lag — across the state.
Your water questions, answered plainly
Is my tap water safe to drink?
Almost always, yes — Water Corporation supplies are treated and tested against the NHMRC Australian Drinking Water Guidelines. What varies from suburb to suburb is how the water feels: taste, hardness, clarity. Your local report flags anything above a guideline limit, checked independently rather than taking the supplier's summary at face value.
Why does water differ between suburbs?
Perth blends water from desalination, groundwater and dams, and regional towns each have their own sources. That's why one suburb's water can be softer or fresher-tasting than the next. We rank every locality against its region so you can see exactly where yours stands.
Where does the data come from?
Every number comes from the Water Corporation of WA's Drinking Water Quality Annual Report — the official testing data — re-analysed independently. Read the full methodology.
