Is Perth tap water safe to drink?
Yes. Perth's drinking water meets the Australian Drinking Water Guidelines, but quality varies by suburb. Water Corporation's 2024–25 data shows supply-zone hardness averaging 29 to 228 mg/L, hardest in the northern groundwater-fed zones, while desalinated water can taste flat. Chlorine is the disinfectant, so taste and smell are common complaints.
