Post flood ICT debrief and improvements to real-time water data support

We experienced some degraded data and systems services during the rain event on the weekend of 20 and 21 March 2021. A post incident debrief brought together the lead water agencies to identify recommendations for improvement for future events.

The cause of the outage was identified as an increase in demand for system access and data that put a significant strain on some WaterNSW IT systems that were located within the NSW Department of Planning and Environment ICT environment, coupled with some network connection issues.

It was found that the IT Systems held up to the event and that staff performed well in a challenging situation but areas of improvement were identified. The Post Flood ICT report makes specific recommendations that are now being implemented by the department.
