Scada's Role in Getting Drinking Water Standards There!

Annual Conference

The purpose of the Drinking Water Standards for New Zealand (DWSNZ) is to ensure that all drinking water supplied in New Zealand is safe and wholesome. Although these standards seem to be straightforward, implementing a system which reliably monitors and provide early warning on the water infrastructure apparatus is not.

This paper will examine SCADA’s role in complying with the drinking-water standards, and the methods of processing associated samples and measurements (Plant->Instrumentation->Remote Terminal->Communication->Processing->Data Storage->Reporting).

The paper will also present some of the real-world issues that the responsible organisations face, and offer a number of solutions and practical examples of how these issues could be resolved. For example:

  • Collected data validity
  • Sampling rates
  • Hand-dressing of data
  • Instrumentation accuracy
  • Dealing with and preventing missing data
  • Traceability – being able to pin-point what went wrong, and where.

Abbey Systems has been working closely with a number of the organisations concerned with the provision of safe and wholesome drinking-water to communities in New Zealand on both local and regional levels.
