Symposium 2016 – H2Opposites; water innovations in contrasting situations


Date: 25th, April, 2016

Venue: Sports and Culture Center, Postbus 5, 2600 AA Delft, The Netherlands


Price (For Students): 10 Euros (including Lunch!)

 Price (For Companies):  100 Euros (including Lunch!)


Every year, the Watermanagement Dispuut of the TU Delft organizes a symposium of a topic related to watermanagement. We are proud to present this year’s upcoming symposium: H2Opposites: Water Innovations in Contrasting Situations.

As the title already suggests, the symposium will be about water innovations and how the needs and what makes the innovations work changes in different situations. The technical side of innovations is not enough to be able to realize an innovation. What makes the difference between a good innovative idea on paper and an innovative development that adds value to society? This of course depends for a great deal on the context; different places, stakeholders and times asks for different approaches to implementation.

Three topics will be covered; Sanitary Engineering, Flood protection and Tran boundary Water management. On these three topics, two speakers are invited who approach the same topic in a contrasting situation; high technical innovation in waste water treatment versus low technical sanitary innovations by doctors without borders, rural versus urban developments for flood protection in cities and how to approach new developments in trans-boundary situations where the cooperation is well established in contrast where the cooperation is the main obstacle.

What should we (not) do as engineers concerning innovation in water management? During this symposium we will be exploring these differences and options together with the experts below who agreed to speak on this day!


Day Speaker


Guus Stelling - Deltares and T U Delft


 Guus Stelling is emeritus professor of TUDelft where he was teaching fluid mechanics and computational hydraulics for almost 25 years. During his career he was involved in the development of hydraulic software systems such as Delft 3D and Sobek. He is the co-founder and scientific director of Stelling Hydraulics where he continues to develop innovative software. From 2010 he started the development of a novel system for flooding and drainage analysis based on GIS and DEMs, known as 3Di.





Kees Christiaanse – Kees Christiaanse Architects and Planner (KCAP),  Zurich

 Kees Christiaanse is an architect and urban planner from the Netherlands. He worked with Rem Koolhaas’ architecture firm, where he became a partner in 1983, until 1989. After this period, he founded the company Kees Christiaanse Architects and Planners (KCAP) and ASTOC Architects and Planners. He worked on several big projects, like the Olympic legacy masterplan for the 2012 summer Olympics. For this symposium, he will talk about ways of city planning and building that not only keep cities safe from flooding but that are also integrated in the other needs of a city, so to make a integrated solution fitting in modern cities. Among other things, he will be talking about the innovative Hamburg Hafencity project for which his company made the design. This solution protects the HafenCity, a new district in Hamburg that is not protected by the dikes from flooding by adjusting the buildings themselves.


Simon Hofstra - Waterschap Brabantse Delta

Simon Hofstra works for Waterschap Brabantse Delta, and is project manager for the Overdiepse Polder, which is part of the 'Room for the River' project and has won the Water innovation price and has gotten a lot of international attention. On the symposium, he will talk about this project, which is a rural development to protect big cities for flooding, by lowering the dykes but keeping the land farmable. It is so innovative because it shows the possibilities of the participation of civilians and how innovations can be integrated in society. Based on this project, he will talk about how to ensure that an innovation adds value to society.



Maarten Hofstra – Unesco IHE

 Maarten Hofstra is a senior advisor in policy analysis and water governance for UNESCO IHE, the institute for water education and has been working for Rijkswaterstaat for the last 40 years. This makes him the perfect candidate to talk about trans-boundary watermanagement in the Rhine Basin since he has been present at the negotiations concerning its development for many years now. In his presentation, he will talk about the difficulties in progress within an international basin, where the different countries have different interests, but the relations are well established. He will explain about process innovation, building blocks for good water governance and the importance of including the stakeholders. Furthermore he will compare the development processes of the Rhine basin to that of the Waal en de Schelde.



Rens de Man- The Hague Institute for Global Justice

 Rens de Man is working for The Hague Institute for Global Justice as a researcher on the conflict prevention program. He is specialized in social problems around land and water use, food security, natural resource management institutions and sustainable development. At this symposium, he will be talking about his work concerning water innovations in Israel and Palestine, who are mutually dependent on shared water resources because the ground- and surface water flow from the West Bank into Israel. He will talk about the lessons learned when trying to implement innovations in for example desalination and waste water treatment in the Israeli-Palestinian negotiations, which are hampered due to lack of peace and stability.


Kees Roest - KWR

 Kees Roest is currently working for KWR, the watercycle research institute, as a researcher in the wastewater & reuse research group. His specific field of expertise is the recovery of resources from wastewater and alternative sanitation. He will talk about very innovative ideas to recover prosperous from wastewater, which was for example implemented at Schiphol, where they now produce sustainable manure form the wastewater of travellers. He will explain the new ideas and approaches and the necessity for retention of very important resources. Furthermore he will talk about the trade-off between expensive high technical solutions and other approaches.




Biserka Pop-Stefanija- Medecins Sans Frontieres

Biserka Pop-Stefanija works as WATSAN advisor working for 'Doctors Without Borders', working for the Canadian Red Cross and the International Medical Corps. With many years of field experience she has a strong view about how innovations in these situations can be approached. She will talk about the work of Sanitary engineers for doctors without borders and the challenges one comes across when trying make developments in field situations, where logistics, safety and ever changing rules and stakeholders change the approach often and why it is very important that it innovations in these situations are implemented.





This year there will not only be speakers at the symposium, we will also organize some workshops!

The topics of the workshops will be connected to the different topics of the speakers. During these workshops you will get the opportunity to dig a little deeper in one of the topics of this day that you find interesting! They will be interactive sessions with 15-20 people which will take approximately one hour and that will take place after lunch. In the registration form below you can give your preference for a workshops or indicate that cannot attend a workshop.

Here follows a short description of the different workshops:

Workshop 1 : Different points of views in urban flood design, by Kees Christiaanse

This workshop given by architect Kees Christiaanse is on different themes. Kees Christiaanse will select different points of views with respect to urban planning for flood protection and he will lead the following discussion.


Workshop 2 : How to solve the phosphorus recovery problem?, by Kees Roest

In the Netherlands we currently have a problem with phosphorus recovery. A lot of phosphorus gets lost due to unsustainable recovery, while it can be a very valuable resource. In this workshop you will think about the different ways to approach this problem in the context of a specific case. Will you use high-tech (but expensive) solutions? Or rather go for a cheaper low-tech solution, which might not totally solve the problem?


Workshop 3 : Corporation & the warming of the Rhine, by Maarten Hofstra

During this workshop Maarten Hofstra will introduce you to a topic that is becoming a very  important one in the Rhine basin management: the heating of the river. During this workshop you will think about the different stakes that are at play and play a role play in which different groups will represent different countries.

Workshop 4: Sanitary engineering for doctors without borders, by Biserka Pop-Stefanija

The workshop is on Hospital Waste Water Management, Cholera outbreak, Port au Prince, Haiti. The discussion will be a specific field case where students are asked to come up with a plan to implement an innovation within the difficulties of that context and present this.
