Central Coast water supplied to Tuggerah comes from the Wyong River and Ourimbah Creek catchments,
treated at the Mardi Water Treatment Plant. The mineral content in this water
accelerates rubber washer degradation in older compression-style taps —
the kind found in most pre-2000 Tuggerah homes. Ceramic cartridges in modern mixer taps fare
better but still wear over time.

A single dripping tap in Tuggerah wastes up to 20,000 litres of water per year.
At Central Coast Water rates, that's a meaningful bump in your water bill annually — and
councils are increasingly focused on water conservation in the Tuggerah Lakes catchment. Fix it
early.
