[POSTPONED] – EWB The future of water summit 2019

Join us for the very first knowledge sharing summit on the subject of “Future of Drinking Water”

Half-day – 5 speakers – 4 project solutions

At EWB-NL we realize that for some communities in developing countries access to fresh drinking water is a stumbling block in their daily life. How would you grant access to drinking water in communities with limited resources, in remote locations? And how would you ensure it will be sustainable? How would you bring into contact the right parties and what does it take to turn an NGO’s effort into success?

These are just a few of the questions our volunteers face on a regular basis when starting a project. As Engineers Without Borders, we are aware that we are just one of many organisations which are contributing to a change in Drinking Water access and Sanitation for remote communities. Therefore, we are organising this event to bring together experts from different backgrounds and projects. Together, we want to share our project experiences, ideas and key contributors to success on such water projects.


With this Summit EWB-NL aims to bring together representatives from various organisations and share ideas and best practices in water project executions. This summit will encourage synergy of ideas and initiatives and lean on lessons from expert groups. This summit contributes to the knowledge sharing of UN SDG #6 on Clean Water and Sanitation – hence we call for action to join!


This is a half-day event, starting from lunchtime on Friday in Delft. The program will be opened by a keynote speaker, followed by case study presentations from water project managers, technology specialists and EWB volunteers.

There will be a couple of coffee breaks which will serve the perfect opportunity to network with other water professionals and speakers. Drinks and cake will be provided, money raised will be allocated to EWB-NL current and future water projects.
