There are totes, and there are totes. Some people use that thin brittle plastic tote that if you look at it funny, breaks. Yours looks like the type (greasy tough durable LDP) that would take a great deal of force to break. I wouldn't worry about it, frankly. I used totes like those for reservoirs and put bulkheads in them with never a problem. The one you have looks like the same material they use for trash cans. I say you're good to go.
