Monitoring and reporting
Monitoring and reporting on the health of waterways.
Monitoring on the quality and quantity of surface and ground water sources.
WaterNSW is responsible for monitoring a significant part of the quality and quantity of NSW’s raw water supply. We operate an extensive water quality and quantity monitoring program to track the raw water quality of both surface and ground water sources. Monitoring includes physical, chemical, biological, radiological, hydrological and meteorological parameters through on-line instruments, field sampling and laboratory analysis.
Sites we monitor include:
We have three main monitoring programs:
WaterNSW is committed to providing up-to-date and transparent data. This includes our Annual Water Quality Monitoring Report. This report is for the Declared Catchment area of Greater Sydney, where our monitoring program extends further than general river health and testing for blue-green algae. It is a detailed annual report, covering our comprehensive monitoring activities for catchments, lakes, intakes to water filtration plants, picnic areas and downstream river sites.
Alongside our annual water report, WaterNSW also provides Sydney Water with key data to enable them to produce a quarterly drinking water report. This report is to inform customers about the quality of drinking water at various stages of the supply system.
You can view the latest quarterly drinking water quality report on the Sydney Water website.
WaterNSW acknowledges the traditional custodians of the lands and waters on which we work and pay our respects to all elders past, present and emerging. Learn more
