Lower North Island council SCADA upgrade from Intouch to ArchestrA

  • Completion date: 2016

  • Track record: Excellent – no unplanned system failures, loss of functionality or loss of data. Project met all the client’s requirements.


The SCADA upgrade was started with the Water Treatment Plant Upgrade in 2014 where AFI was selected as the vendor for the plant control systems. Part of this project was to develop an entirely new SCADA platform, with dual historians and new visualisation standards which were later rolled out across all other SCADAs managed by the council.
