In addition to site analysis and inspection, Sydney Water’s Spatial Hub can perform tasks such as tracing upstream of sewers, modelling flood risk and simulating outages. This increased situational awareness helps improve asset maintenance and results in better customer outcomes.
“We use our own records [and] we use data from all sorts of disparate sources — but having the Nearmap product in there gives us a real powerful source to see,” said Dino Scotter.
As part of its wider asset maintenance network, Sydney Water monitors approximately 10,000 level-switches located in sewer-access points. These sensor-driven switches trigger an alarm if certain thresholds are exceeded. Spot-readings from the sensors provide valuable real-time information. “This is IoT [Internet of Things] technology now,” said Dino Scotter.
Dino explained that overflows in the Sydney Water network can result in financial penalties from the NSW Environment Protection Authority (EPA). With thousands of kilometres of sewers to maintain, real-time information from sensors helps Sydney Water prioritise preventative maintenance programs and repairs.
Just as Dino was telling us this, an IoT sensor alert flashed on his screen in Spatial Hub indicating a potential fault or maintenance issue needing attention. Dino showed us in real-time how the Sydney Water team uses Nearmap imagery within Spatial Hub to help manage such occurrences.
As soon as a sensor alarm alert is received, Dino can identify the location on a basemap.
