Real-Time Data Integration with Yorkshire Water’s Pi System

The problem

According to Yorkshire Water’s Cook et al, despite significant on-going investment, water companies continue to receive an unacceptable number of discolouration related customer complaints.

In 2010 Yorkshire Water (YW) implemented a telemetry infrastructure to support their business goals by providing high quality operational information to help it improve business performance.

This was because previous systems were complex to maintain, and YW was mindful of system limitations that restricted the collection and analysis of real time data.

The solution

The current system a solution put together by Capula, utilises the PI System infrastructure from OSIsoft and is able to measure and collect data from a range of sources including Instruments, plc’s, remote telemetry units, and data loggers, among other sources.

Since 2008 Caption Data Limited have been working with ATi UK to provide telemetry for a range of instrumentation. The latest application sees Caption Data’s RDL//nano integrated onboard ATi’s disruptive Turbidity monitoring technology.

Working with YW’s Real-Time Data Development Specialist, Caption Data were able to provide instant access to data as soon as it’s available, through a simple but secure connection between YW servers and their own.

Steve McGuin, YW’s Real Time Data Specialist says “Ease of integration is what we’re about. We were able to implement data from the CDLSmartHub against our standard structure by connecting our servers with Caption Data servers.”

“Through this method we are able to collect data from CDL servers every ten minutes, back it up and make it available as soon as it arrives”

The Product

Nephnet portable turbidity sensor with remote monitoring capabilities small

NephNet turbidity monitoring system by ATi UK

NephNet is the first battery powered, portable turbidity monitor that gives the same performance as the more traditional fixed monitor, with no compromise on accuracy at low levels.

Before ATi partnered with Caption Data the data was being collected via a USB data logger, this provided excellent levels of granularity in terms of sampling time and accuracy however the data had to be retrieved manually, this would cause issues as the data could show alarms that were missed due to the slow reaction of analysis.

Within a water network hundreds of turbidity monitors could be deployed. Traditionally that would mean a technician would have to visit each one to collect data.

Now with the embedded technology provided through the RDL//nano, the NephNet is able to provide real-time data via Caption Data’s CDLSmartHub.

Tristen Preger, Sales Manager Utilities, said “It was clear at an early stage the market required telemetry for the NephNet turbidity monitoring system and we needed to act quickly to gain traction as quickly as possible.

“We engaged Caption Data to specifically collaborate on remote monitoring of the NephNet over 12 months ago and have enjoyed a very successful relationship with them on this unique innovation.

“Caption Data assisted us in integrating the telemetry system seamlessly, quickly and easily into our existing system.”

Lets take a look under the bonnet:

  • Turbidity data is collected by the RDL//nano base stations integrated into the NephNet sensor
  • The RDL//nano then transmits the data to Caption Data’s secure servers via GPRS using fully roaming SIM cards
  • When data is received by Caption Data’s servers it populates the CDLSmartHub databases
  • If the data belongs to YW – it is stored in a file and directory for where YW can access it
  • YW’s servers request individual files from our servers and the files are transferred securely
  • The data is then backed up and processed by YW
  • Lastly, once files have been successfully transferred to YW’s servers they are automatically removed from our servers

Dan Mackdemott, Director at Caption Data explains, “We don’t believe in complexity. Time and resources can be saved by keeping it simple, and that’s how we work.”
