Daily drinking water quality report

Assurance your drinking water is safe

Every day, we produce a report to confirm that our water filtration plants and water delivery systems throughout Greater Sydney are performing as they should. It's your confirmation that you're receiving the highest quality drinking water. We also do water analysis so you can check pH balance and hardness.

PFAS: what's the story?
If you're concerned about PFAS levels in dams and catchments, we can reassure you that your drinking water is safe. Find out about PFAS and drinking water.

How we keep your drinking water safe

Learn about the quality of drinking water in your area

Our systems are interconnected. At times, your drinking water may come from different water delivery systems. For example, Blue Mountains residents may receive water from either Cascade or Orchard Hills Water Filtration Plant. This depends on operational needs and storage capacity.
