AQUIS Key Collaboration Partner

Over the years many users have contributed to the development of AQUIS. However, a British colleague, John Machell, is a winner hands down in terms of leaving a distinctive mark on the product. The development of AQUIS is ongoing and John predicts that in the future AQUIS will play a more prominent role in an operational environment.

In the late 1980s the British water industry was privatized and that promoted industry modernization process noticeably, John explains. At that time he worked with IT and distribution at Yorkshire Water Services.

Senior management at Yorkshire Water wanted to improve the efficiency of many business processes so John started to think in terms of more advanced modeling issues that could provide continuous information about flow and pressure data from distribution networks. Management realized the potential of the modeling project, and John started looking for competent collaboration partners.

Danish willingness to cooperate

"On a worldwide basis at that time there were only three modeling solutions with potential to do the job. However, it was only the people behind LICwater, the current AQUIS, who really wanted to listen to our demands and requirements," says John. Today, John works with network modeling and other water supply system challenges at the University of Sheffield.

The close development cooperation between John and 7-Technologies (7T) began in 1991, and continues today. "The cooperation has always been comfortable thanks to the Danes having a relaxed and competent work attitude. This generates a great atmosphere and I always feel that I can speak freely. The cooperation has had quiet periods but also very intense periods. This was the situation for example in the period from 1994 to 2000 during which time I also did my PhD on ”Water Modelling in Distribution Networks”, which was based on AQUIS."

A proactive future

The result of the AQUIS development was an advanced real-time software solution that would enable water utilities to make the step from reactive to proactive management of water supply systems. The development moves fast, however, and John is very optimistic about the future of AQUIS. He currently works in collaboration with 7T on an EPSRC funded project called Neptune. 

"AQUIS has gone from being an application for domain experts to a very user-friendly and stable application that can be embraced by operational users in the field and thereby pave the way for more efficient operational practice.

The industry is poised to make use of these advanced hydraulic modeling capabilities. The improved user-friendliness and parallel advances in wireless communications technologies have now made it possible for non-experts to render a very proactive management of the water supply network.

The bottom line is that  in the future tools like AQUIS will not only be used for design and planning, but also for proactive real time management of the water supply network."

John MachellJohn Machell’s career within the water sector has been long and varied and since leaving the industry in 2005 he has been a member of the research team within the Pennine Water Group in Sheffield where he continues his involvement in water supply projects.
