Water needed to be pumped -2.5km away from the quarry up a hill to act as the water supply reservoir to the PPC main building and gardens. For this to be possible a wireless link was needed between the pump station down at the quarry and the reservoir up the hill. The client also wanted to report data to the SCADA room some 1.5km away from the reservoir.
The overall objective of the wireless pump project, was to maintain a certain reservoir level at all times by pumping from the newly build dam at the bottom of the hill (quarry). Level control is possible via the wireless radio link established between the pump station and the reservoir level sensor. It indicates the exact level of the reservoir and hence start/stop the 55kW motor and pump. In auto mode pumping is restricted to afterhours which are leading to cheaper electricity usage.
