Please refer to the below figure for requirements for the design of foundations.

In addition, the drain should consist of an elbow set flush in the concrete and piped to an acid sump or sewer.  Each drain should be equipped with a strainer.  Elbow, pipe, and strainer should be of an acid resistant material.

Protection of concrete against acid spillage should be: Two coats of Coal Tar Epoxy or Epoxy Mastic applied on all exposed concrete surfaces after suitable surface preparation, including the outer vertical surface of the foundation extending about 12 in below finished grade.

When specified, areas around connections (e.g., takeoff, sampling) should be faced with acid resistant tile and mortar.
