Mt. Eliza supply zone
Moderately hard
69mg/L total hardness (range 56–83)
Water in Mt. Eliza is moderately hard. You may notice some scale over time on kettles and shower screens, but it’s manageable. Carbon filtration improves taste; softening is optional.
Other figures worth knowing
Chlorine by-products (THMs)0.069mg/L
pH7.82
Dissolved solids444mg/L
Sodium118mg/L
Perth's water is disinfected with free chlorine at roughly 0.4–1.0 mg/L network-wide. The figure above is trihalomethanes (THMs) — by-products of chlorination that a catalytic carbon filter reduces. In Mt. Eliza they run at about 28% of the safety guideline.
