Water quality monitoring program

Water quality monitoring and testing currently meets or exceeds international standards of safety and acceptability.

Sydney Water and the Sydney Catchment Authority operate according to a water quality monitoring plan endorsed by NSW Health.

The program includes:

• catchment monitoring to identify and manage any risks of contamination
• monitoring water quality characteristics that provide early indications of the presence of Cryptosporidium and Giardia
• increased monitoring during storms or other events that could influence water quality
• testing treated water at Warragamba, Orchard Hills and Prospect water filtration plants six days a week for Cryptosporidium and Giardia.
• weekly monitoring of low risk water storages for Cryptosporidium and Giardia.

These actions support the objectives of the Sydney Water 5 Year Drinking Water Quality Management Plan, as endorsed by NSW Health.

Sydney Water is committed to keeping customers informed about drinking water quality through daily and quarterly reports.
