ABSTRACT

The Central Queensland University (CQU) and industry partner GBG Project Management Pty Ltd have been developing Supervisory Control and Data Acquisition (SCADA) technology to remotely operate and monitor large scale on-site wastewater treatment and reuse systems. The current trend towards decentralised systems is increasingly of interest in this area. Issues identified with these types of systems in the past have included the use of inappropriate technologies, hydraulic surges, difficulties in monitoring operation and identification of maintenance issues. The SCADA technology is used in association with KEWT systems, an innovative series of recirculating filter and evapotranspiration beds. It has allowed for the minimisation of hydraulic short-circuits and the calculation of evapotranspiration volumes. The SCADA system has also been designed to identify maintenance issues, especially in regards to pump performance and pump line blockages or ruptures.
