Perth Water Quality · Sourced from Water Corporation

What's actually in your water?

Type your suburb or postcode to see your local water quality — hardness, what it means, and the full breakdown. Every figure comes straight from Water Corporation's official 2024–25 report.

Try Mount Hawthorn, Yanchep, Mandurah or Fremantle — or browse all localities in the table below. Wondering whether Perth water is safe to drink? →
Searching by postcode? Supply areas follow water infrastructure, not postal boundaries, so one postcode can span two areas. If a result looks wrong, search your suburb name instead.

Source: Water Corporation Drinking Water Quality Annual Report 2024–25, Perth Region (aesthetic & health tables). Figures are locality means with min–max range. Verified July 2026. Water is reported by supply locality, not individual suburb — your suburb is matched to the locality that supplies it. Supply boundaries aren’t published street-by-street, so this matching involves some interpretation — suburbs near a boundary may be served by a neighbouring locality. All Perth localities met health-related safety requirements in 2024–25.
