Working Together with the Water Industry
Presentation Tuesday 8 November 9.00 hrs

The talk will address a ranges of issues related to collaboration between researchers and practitioners from the academic perspective. A number of related topics will be mentioned and analysed including means of successful collaboration, potential barriers and how to overcome these, modes of financing and supporting research and ultimately benefits to both academia and industry. All this will be illustrated on a number of real-life examples from Prof. Kapelan’s past and current collaboration with the water industry in the UK and abroad.

Prof. Zoran Kapelan is Professor of Water Systems Engineering and Head of the Water and Environment Group at the University of Exeter. He is an IWA Fellow and a chartered member of CIWEM with over 27 years of experience in both academia and industry. His research interests include a wide range of topics in water engineering with focus on urban water management and related water and wastewater infrastructure. His research work resulted so far in a number of new methods and techniques currently used in practice including a novel event recognition technology that is now used companywide in one of the largest UK water utilities. Prof. Zoran Kapelan is currently leading 8 research projects with 5 large UK water companies. He has over 350 technical publications and a patent. Further information available at

Working Together with the Researchers
Presentation 7 November 9.00 hrs

The Dutch water industry has a long experience in working together with fundamental researchers at academia, applied researchers in research institutes and practical researchers at consultancy companies and water utilities. This close collaboration has brought mutual benefits leading to a system that can be characterised as very successful. A very important feature of the interaction is learning to speak each other’s language and understanding each other’s interests and goals. Searching for the overlap and realistically recognising and respecting limitations leads to rewarding results as will be shown in some characteristic developments and achievements.

Loet Rosenthal is Director Water Supply at PWN Water Company North-Holland. He is a member of PWN’s board of directors and responsible for the water supply division at PWN, which supplies drinking water to the major part of the Province of North-Holland (1,7 million inhabitants). He has about 25 years of experience in the water industry, working in research, consultancy and management. One of his former employers is Kiwa Water Research (now KWR Watercycle Research Institute), where he was responsible for research on network asset management. On behalf of PWN he is involved in coordinating research within the Joint Research Programme (BTO) of the Dutch water utilities. Loet Rosenthal is also a director at WRK. WRK is a joint utility of PWN and Waternet supplying pretreated surface water from the River Lek (Rhine) and Lake IJssel to PWN and Waternet for further treatment to drinking water in the dune area of North-Holland, and to industries for production purposes.

Flow dynamics in a pipe with a sudden change in diameter
Presentation 7 November 14.20 hrs

The calibration of a numerical model of an existing Water Distribution System (WDS) that contains old pipes is usually based on the estimation of the roughness of the pipes. Due to the lack of information, nominal pipe diameters are generally used in the model development and the change in pipe diameter due to pipe wall build-up is compensated by adjusting the roughness value… (please click on the PDF to read more)

Leveraging Big Data for Intelligent, Water Management
Presentation 7 November 14.00 hrs

For years, water utilities have relied on automation systems to help manage the water lifecycle and these systems generate vast amounts of data that must be effectively managed in order to enable intelligent decision making. Today, the term Big Data is used to describe many, complex sources of data that generate vast volumes, often in real-time. Within a water utility, Big Data includes… (please click on the PDF to read more)
