Most industrial organizations simply ensure the eyewash is used long enough so the material washed off is in de minimus concentrations and can go safely down the drain. A few moments of calculation will show that at the standard eyewash flowrate this is very supportable.

Subject: [DCHAS-L] Lab eyewash/safety shower drains
Good Afternoon,
Once again the following concern has arisen: lab eyewash/safety shower units cannot drain with regular water due to possible contamination of the environment, e.g., if someone were washing off a sulfuric acid spill. Can someone provide a reference that this is (or is not) okay?
Thanks!
Ruth Ann
