It would seem pointless to have an education faire for an industry rather than a profession. "Come and see what you can do working in the Water industry!" -> you could be a hydrologist, a lawyer, a receptionist, a pipelayer, a sysadmin, a farmer, a payroll officer... it's nonsensical, given the context. It'd almost be easier to list the jobs that can't be shoehorned into such a broad industry.
