What if you could prevent water pollution, so you can have a nice swim during a hot summer day? What if you could predict your house being flooded, so you can take measures to prevent this? Does this seem far-fetched? It is not. Most of the data to be able to do this is readily available, however most people are not aware and the data is sometimes difficult to understand.

This is the point where you come in. Take on the #WaterChallenge and make this important water data accessible for everyone. This is formulated into the main question:

Come up with ways to visualise the data of the SCOREwater project, plus enrich it with external data sources, to make it interesting and useful for citizens.

*The list of open data-sources will be provided on March 1, the start of the Water\challenge, but you are allowed to use other data sources as well.
** This challenge is accessible for anyone, as long as you are able to visualise your idea. New ideas and existing ideas are eligible for participation. Terms and conditions can be found at the bottom of the page.



The #WaterChallenge will be open for your contributions from MARCH 7 until APRIL 10


*This link will be active during the runtime of the challenge



Before you start you have to register your team (4 persons max), or participate on your own.


Work on your innovative idea to make sense of the water data.


Present your work digitally in front of an expert jury.


Win an all-inclusive trip to one of the SCOREwater cities (Amersfoort, Barcelona, Göteborg) to present your idea and talk about possible follow ups.

This challenge is connected to the EU-funded (Horizon 2020) research and innovation project SCOREwater. It focusses on enhancing the resilience of cities against climate change and urbanization by enabling a water smart society. The project develops smart (sensor based) solutions in three different cities, Amersfoort (Netherlands), Barcelona (Spain) and Göteborg (Sweden). The overarching vision is to link the physical and digital world for city water management solutions.

A lot of data has been gathered within this project and to make the most of all this data we set up this challenge. The project data contains for example: data on water quality at construction sites; soil moisture levels in the city; chemical composition of what is being flushed down the toilet. These data are useful for organizations and municipalities involved in the project, however it is still unreadable for the average citizen.


Participation in the #WaterChallenge  is open to all: startups, university students, researchers, professionals, citizens and associations. One can join this challenge as an individual or as a team of maximum 4, register to join. Please read the terms and conditions, which can be found at the bottom of the page, before applying.

We are expecting that you answer the main question through a so-called ‘paper prototype’. This means that we don’t expect you to create a full app, website, or fully worked out solution (although the more effort you put into it, the higher that chance you win). Paper prototyping comes from the design world, and it is the process where a team creates a ‘paper’ representation of a digital product. Please read the terms and conditions, to get the full list of conditions it must meet. 

  • March 7: open for contributions
  • March 15, 16:00-17:00 (UTC+1): Q&A session 1
  • March 30, 11:00-12:00 (UTC+1): Q&A session 2
  • April 10: deadline contributions
  • April 19, 14:00-17:00 (UTC+1): best scoring contributions will present for the jury

Below a link to the PDF in which all the data sources are compiled. You are free to also use other, free data sources in your paper prototype.
