Partnering opportunity

Dutch rail infrastructure manager is looking for innovative solutions to prevent flooding in tunnels at railway stations after extreme rainfall


The Dutch rail infrastructure manager has to cope with more periods of heavy rainfall due to climate change. To keep their train stations accessible they need to find innovative and sustainable solutions to prevent tunnels from flooding. A technical or research cooperation agreement is aimed for. The company is kept to public procurement but creative solutions can contribute in defining requirements. This request refers to an innovation challenge published on an open platform.

Technical Specification or Expertise Sought

The company strives to be adaptable to climate change and help preventing this by lowering their CO2 emissions and energy requirement, but they need the help of others to find innovative solutions. Together they want to find new ways to avoid tunnels from flooding by collecting, draining or reusing water in a smart and innovative way.

Partner sought

The company is especially looking for companies experienced in construction of buildings or infrastructure in the utility sector. Developers and designers of bridges and tunnels or other civil engineering projects are kindly invited to share their ideas to contribute in finding solutions. The Dutch rail infrastructure manager has to stick to public procurement but specific innovative solutions can contribute in defining requirements. On the long term companies can get a benefit out of their contribution.


Nowadays extreme rainfall occurs more frequently because of climate change. In a short time a lot of water can fall down and has to find its way. But there also periods of drought and very high temperatures due to the climate change when there is a need for water. During and after heavy rainfall a lot of water has to be drained or collected to prevent nuisance and keep the train stations accessible. The combination of the two phenomena, increasing frequency and higher intensity of heavy rainfall, is increasing the need to find solutions how to deal with flooding. At present the fire department and the incident unit are using the pumps of the fire department to clear the tunnels after flooding. But pumps have their disadvantages: Their use of energy, they are expensive and complex to fit in existing situations. And it would be preferable to reuse the water. The rail infrastructure manager is looking for solutions to prevent tunnels from flooding to keep their train station accessible. To help them achieve their sustainability goals they are especially interested in low tech and out of the box solutions that lower their CO2 emissions and energy requirement and are made of circular materials. The company is kept to public procurement but creative solutions that show great potential will be in the running for realization. They are looking for cooperation with partners that can help find sustainable solutions with a clear proof of concept that is cost-effective. Cooperation with partners such as institutes, universities and companies would be in the frame of a research or a technical cooperation agreement.

How it works

  • Tell us about yourself
  • We’ll discuss with you
  • We put the right partners in touch

EEN help you find the right partner, rather than you going it alone.

Our role is to review and collate the most suitable submissions, and then send them to the client who posted the opportunity. We consult with you, and the client, to make the process professional and easy.

These are live opportunities. Your registration of interest on the site is just like a professional approach to a business at a networking event. To stand the best chance of success, make your submission really sing. Sell why the client who posted the opportunity should work with you. Excite them. Ask questions. Try and avoid copy and pasting words from elsewhere.

Once the client has chosen their partner, we'll introduce them over email and keep in touch with both parties to see how it's going. Sometimes things progress quickly. Sometimes because of changing priorities for either party, things progress slowly, but you never know - your next big business break could start right here.
