Helder: a podcast about water with researcher Marjolein Vanoppen

Client: Marjolein Vanoppen, Aquaflanders & B-IWA

The goal

On World Water Day, we officially launched a new podcast called ‘HELDER – over drinkwater‘, hosted by world improver and water scientist at Ghent University, Marjolein Vanoppen. Marjolein researches water purification and industrial and circular water technology and often gives lectures about water at universities, schools, and associations across the country.

When I talk to people, I notice that very few Belgians know where our drinking water comes from and what is in it. So my main goal is to inform people about the quality of our drinking water. Drinking tap water is perfectly safe here in Belgium and yet we remain one of the countries with the largest consumption of bottled water. So I want to raise awareness, show what science is doing and offer transparency.”

Our social story

The idea for this podcast has its roots in the Podlab XL project of our colleague Pieter Blomme and podcast friend Eva Moeraert. After a pilot episode was created, the Chase Creative team, including Pieter Blomme as lead audio storyteller, Wederik De Backer as an audio editor, our COO Jan D’hont for consulting and audience development, and senior account manager Anastassia Oudovitchenko, took the next steps.

We coached, edited, mixed the 7 episodes and created an audience development plan around this show, including:

    • hosting & publication
    • press campaign
    • social advertising campaign
    • dedicated podcast landing page & copywriting
    • podcast art & graphics
    • creation of audio & video teaser



Is tap water healthy? Can it be contaminated with hormones? Is there enough drinking water on the planet? In every episode, Marjolein Vanoppen talks to a panel of experts about the most precious raw material of the next decade. This together with her dad who can be skeptical sometimes, which gave the format a bit more body in an authentic way.


The result

Nearly 75% of the listeners listened to the end of the podcast. In the first week of release, we were the Belgian number one podcast on Apple podcasts in the earth sciences category and different media such as VRT NWS covered it.
