Water quality in Dwellingup

Your local water hardness and the full breakdown of 16 parameters, sourced from Water Corporation's 2023–24 report.

← All Perth suburbs
Dwellingup supply zone
Soft water
29mg/L total hardness (range 26–32)
Water in Dwellingup is naturally soft. You likely don’t need softening — scale build-up should be minimal. A sediment and carbon filter still improves taste and removes chlorine.
Other figures worth knowing
Chlorine by-products (THMs)0.03mg/L
pH7.02
Dissolved solids142mg/L
Sodium35mg/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 Dwellingup they run at about 12% of the safety guideline.

What this means for your home

Water in Dwellingup is naturally soft. You likely don’t need softening — scale build-up should be minimal. A sediment and carbon filter still improves taste and removes chlorine.

✓
Our honest take: You probably don’t need a softener. A 3-stage filter still helps with chlorine taste and sediment.
