Mechanical Heritage Volunteer
In this interview with Jaap Hospers, a volunteer with the Mechanical Heritage Center in Dronten, we discover the mechanical tools that are used to make the polder in Flevoland. What does it mean to live in the polder? What are the things you can find in the ground where there used to be water? Where else than in the Flevoland polder is it possible to find an old metal boat in the ground of your backyard?
Urban planner & Landscape architect
With Ria and Anette, we spoke about the ideals of the current Urban planners and landscape architects that form the city of Almere. How do you make a city where nature can have also a strong voice in the planning? Because what makes Almere a good city is its blue and green base. A good example is the new neighbourhood in Almere: Duin.
Retired Civil Engineer and soil researcher
Imagine you arrive at a huge empty landscape without any buildings and only sand and some vegetation. What kind of city will you build in this space? With Bouwe we talk about the soil that is the base for the city of Almere and the work of a civil engineer. What is the role of water in de engineering of a new city?
Water System Analyst
In the interview, Joost Stoffels, a water quality expert in Amsterdam, discussed the city’s efforts to improve water quality and promote safe swimming locations. He differentiated between official and unofficial swimming spots and emphasized the importance of caution when swimming in Amsterdam’s waters. Joost also shared fond memories of water-related experiences. As a water worker, he has witnessed the growing trend of wild swimming and the increasing public interest in water quality, driving his passion for ensuring cleaner and safer waters in the city.
Advisor Climate Adaption
Throughout the interview, Soesja sheds light on the positive transformation of Amsterdam’s canals, which have gone from being too polluted to swim in during their childhood to now attracting people for refreshing swims on sunny days. As a professional specializing in water and climate adaptation, she provides unique perspectives on the evolution of water management and the challenges faced by the Netherlands, particularly concerning dike maintenance and rising sea levels.
Project leader, Environment Management
Discovering Environmental Stewardship: In a recent interview, we explored the world’s largest sea lock project with Jan Rinstra, an esteemed environmental manager. Jan’s primary role revolves around water management, emphasising eco-conscious policies. Throughout the discussion, we learn about the IJmuiden Sea Lock’s significance in promoting sustainable practices and its vital function in enhancing water resources, countering the effects of climate change, and facilitating maritime traffic with its impressive engineering.
Historian and City Guide
The chairman of De Amsterdam Cultuur-Historische Vereniging. This society aims to share knowledge about the history of Amsterdam. He is a city guide, and during our talk, he tells us about Amsterdam, het IJ, Noordzeekanaal and Amsterdam-Rijnkanaal coming into being. Did you know the harbour in this city moved from east to west? You will hear all about it in our talk with Aaldrik.
Informed Layman
With Ingrid, we spoke about the basics of water management in Amsterdam. She explains some terminology we will hear more often during these water talks. The talk is about love for and fear of water and the pros and cons of living in a delta.
Hydrologist
Being a Hydrologist, Maartje works at Waternet as a senior project manager and consultant. She knows all about the importance of securing the right water levels in the city and how to regulate them. When too much water is in the city, it needs to be pumped out. This happens at IJmuiden, where excessive water gets pumped into the sea. At times of drought on the other hand, large amounts of water are being pumped into Amsterdam from the IJsselmeer. How to regulate this well? Maartje Faasse tells us about her work.
Former Harbour Master
Cor is a retired sailor, salvage expert, and harbour master of the port of Amsterdam and harbour master of the North Sea Canal. In this interview, Cor tells us how Amsterdam as a port is connects to the world, to the world’s oceans on one side, and the °hinterland° (Germany and beyond) on the other.
Cor helps us understand the practicalities and usefulness of the North Sea Canal and the Amsterdam-Rijnkanaal for the city of Amsterdam and its surroundings.
Amateur Historian

Sewage Treatment Operator
Jacqueline Hek is a water treatment operator, she manages the sewage treatment plant on Terschelling. Jacqueline takes us through the process of purifying sewage water into water that is clean enough to enter the sea. She talks about her finds in the sewage treatment plant, what has she learned about humanity? Water sample: sewage samples before treatment.
Process Operator
Hessel Rozenga has a lot of power on Terschelling. He is responsible for all drinking water on the island. From checking the drinking water installation and the pipe from the mainland to Terschelling, to repairs at people’s homes. Hessel explains how water is purified into drinking water. He himself does not drink purified water, but directly from the ground. So why do people still want purified water? And could we also purify sewage water into drinking water?

Salt Agriculture and Chef
Flang Cupido is a pioneer in saline agriculture on Terschelling. As the groundwater becomes saltier, normal agriculture can produce less and less good food. Saline agriculture is a solution. The Zilte Smaak is a practical case of how you can grow fruit and vegetables in soil that is becoming saltier. It’s also still very tasty. To compensate for the salty soil, fruit becomes much sweeter. What are the things we will eat in a saltier future?
Water sample: 2/3 salt and 1/3 sweet sourcewater
