Watertrek’s mission is to raise awareness and alert general audiences about the need to protect aquatic ecosystems threatened by plastic pollution, global warming and toxic chemicals. Watertrek introduces expeditions combining sports (aquatic hikes by stand-up paddling as well as traditional hikes), citizen science and collaborative art, a three-tier approach combining motion, pedagogy, and creation. Furthermore, it offers water-themed content and reproductions of these adventures.

The stand-up paddle or SUP is a derivative of the Hawaiian canoe, the ancestor of modern surfing, formerly used by Polynesian kings. It is practiced standing associated with a paddle.


Severine Vasselin founded the organization Watertrek in 2013 after having practiced stand-up paddling for the first time on the Côte Bleue near Marseille:

“This experience was a true revelation, a change of perspective both physically, socially and spiritually, a shift in my esthetic point of view of scenery. Physically standing up on the water while being far from dry land that requires balance, to me it seemed necessary to remind everyone of the living beauty of which we are all an integrated part.”


Watertrek organizes long and short distance paddle expeditions. These initiatives have both a scientific and cartographic vocation - mostly in rivers - allowing to collect information about the quantity, the source and classification of waste and pollution present in water.

The projects led by Watertrek are in line with 3 of the Sustainable Development Goals as defined by the UN.

Watertrek feeds citizen science platforms in collaboration with its partners (Surfrider Foundation Europe, Freshwater Watch in Oxford). The association is one of the actors of the Steering Committee on the Protection of Transfer Routes launched by the French Ministry for Energy Transition. It contributes to the identification and mapping of waste accumulation areas observed along banks with CEREMA.


Our expeditions integrate both esthetic, artistic, and collaborative dimensions.

Watertrek is happy to share its experiences with you under various creative forms - films, podcasts, books, exhibitions - and use those as a starting point to talk about water preservation.

    Descent of the River AA between Remilly and Setques for Stéphane's northern crew

    3 stand-up paddle boards, 5 hours of paddling along the Aa river between Remilly Werquin and Setques in the north of France… that means 50 kg of waste collected. The objective of our Nordic crew was simple: to discover the river and collect as much waste as possible along those 9 kilometers. “We chose to go […]
