The brute cans are NSF certified.
From my understanding posting a picture of the trash bin without posting manufacturer details about it won't get you a good answer if it's "safe" or not.
The NSF certification ensures that the product won't leach any chemicals into whatever is stored inside and are considered safe to use for food/liquid storage.
You could even look at other Rubbermaid cans like the Brute but notice they don't have the NSF stamp. That being said I've used and I know many other people have used plastic bins/trash cans to make trickle towers or to store water and never face any problems. You can either take the chance or get a certified product.
