Be Ready for Western Australia's
New Chlorine Testing Rules

From 1 January 2025, Water Corporation of Western Australia mandates digital chlorine meters for all potable water disinfection verification under DS63 Update Bulletin 24-02.

Visual methods such as test strips or colour charts are no longer acceptable. Contractors must now use reliable, calibrated instruments to meet the mandated 4.0–6.0 mg/L free chlorine range.
