The bad languages will say that it is aptly named. In any case, the Vilaine is not a model of cleanliness - alas for her. We could even say that it is a real dump. This is what the cleaning agents found there when it was emptied. Edifying!
60 bicycles, 1 motorcycle, 1 scooter, 20 shopping carts, 22 construction barriers, 10 track separators, 60 signs, 20 traffic cones, 20 tires, 15 x 80 1 trash cans filled with glass bottles, 10 trash cans, 20 bins of plastic bags and bottles, 10 tarpaulins, 1 signpost, 1.5 m³ scrap, various clothing, 30 household appliances (vacuum cleaner, toaster, kettle, hair dryer), 1 laptop, 1 cash register, 1 tent cloth, 1 duvet, 2 sleeping bags ...
Here is the list of garbage and objects that the maintenance agents of the Vilaine collected in the river during its emptying, in November, between the lock of the Count (Roazhon Park) and the lock Dupont-des-Loges . An emptying which also allowed the city of Rennes to carry out repairs on the banks of the Marc-Elder alley.
Waste that required, to evacuate, 22 trailers and 12 dump trucks. So no, the Vilaine should not be considered a trash.
