Using historical data and Seeq analytical software, Nukon calculates when sewer blockages will occur up to 13 hours before occurrence, preventing spills.
Often the first notification of a spill comes from a member of the public, hours and sometimes days after the actual incident. Such late notice can intensify public health and environmental impacts, and increase the cost of cleanup efforts.
Following a sewer spill at an environmentally significant site at Midway Point in Tasmania in August 2017, the statewide water utility sought a way to reduce the likelihood and impact of future spill events. To do this, they needed a way to predict future sewage spills, with plenty of notice so preventive measures could be taken.
