Case Studies

Dee Valley Water Upgrade

Netcontrol utility communication products provide communication solutions to the water industry.

Dee Valley History

Dee Valley Water supply water to North East Wales and the North West of England which covers some 831 square kilometres. It operates eight impounding reservoirs, two river abstractions and two ground water sources to supply approximately 62 million litres per day of water to 257,000 customers. For the last seven years they have been using Netcontrol as their first choice for their data telemetry needs.

Recently Dee Valley Water was in the position to make some improvements to their communication systems, when they heard about Netcontrol’ new PDR 121 data radio. They were one of the first companies to order data radios as part of their data telemetry upgrade programme.

 

Versatility of Data Radios

The different topographical locations which Dee Valley Water operates in provides a perfect example of the versatility of the data radio’s. One such site is their main pumping and water reserve centre found near to the Chester City centre. This site is also used as Dee Valleys SCADA control centre, from which all substations and water treatment centres are monitored.

Software interface

On installation at the site Tony Vitelli, one of Dee Valley Waters Communication Engineers, comments on the Radius PDR 121; “the set-up was simple, and configuring the radio has been made even easier through the enhanced software interface. These improvements have made the job that much simpler. Now the whole process takes less than ten minutes from the time you arrive to the system test and pack up”.


Monitor and Reporting

Another area where the Radius PDR 121 data radio has been installed in the Dee Valley Water network, can be found in a sub-station in a remote rural location that serves as a water pumping station and a treatment centre for the local community. The data radios have to be able to monitor and report any malfunction from both the pumping station and water treatment section. Tony Vitelli says “one of the main reasons for using Netcontrol and its data radios is that they provide a level of security for us.  The radios are as reliable as they can be. In the many years we’ve been using them, we’ve never had one radio with a problem, which is imperative in locations like this”. 

Challenging Transmission

An ideal location for the Radius PDR 121 can be found in one of Dee Valleys water towers found across the city from the main base station. This particular location provides a regular challenge for the Radius PDR 121 as the data signals have to travel across a busy city which is full of interference waves which could affect how much data is received at the base station for this site. However this environment proved to have no change to the data radios operational efficiency when communicating to the base station.

Forward Error Correction

The possible interference levels of such an environment are significantly reduced due to the Forward Error Correction facility found in all new Radius PDR 121 radios. The benefits of such functionality are in its utilisation of an interleaving function that enables the data radio to perform well in high interference environments.

Radius PDR performance

Tony Vitelli commented on the Radius PDR121 performance on the day “before the upgrade to the PDR network you could visually see the transfer of data taking place, on the new PDR data radio with its 9600bps rate if you blink you’d miss the operation, making the whole process much more seamless”
