Tamworth Hill supply zone

Soft water

47mg/L total hardness (range 47–47)

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

Other figures worth knowing

Chlorine by-products (THMs)0.013mg/L

pH8.11

Dissolved solids129mg/L

Sodium21mg/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 Tamworth Hill they run at about 5% of the safety guideline.

What this means for your home

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

✓

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

About this supply area: Water Corporation reports quality by supply locality rather than individual suburb, so the suburbs listed at the top of this page all share the Tamworth Hill figures. Your exact property may vary slightly. Water Corporation doesn’t publish supply boundaries street-by-street, so matching suburbs to localities involves some interpretation — homes near a boundary may actually be served by a neighbouring locality, and figures there can differ slightly.
