Water treatment plant? That sounds like an excellent place for an ethics team—though it would, in practice, be nearly synonymous with an environmental impact team.

A bar? Too small an organization; if they had an ethics team I'd just think they were a money laundering front.

Frankly, most organizations above the size of an average mom & pop operation like a local bar should have at least some formal consideration of ethics, and most larger than (say) 50 employees should have at least one dedicated ethicist on staff. With veto power over operations.

Our society has treated ethics like the exclusive domain of ivory tower eggheads and philosophers for far too long, and look at what it has led to. If nearly everyone knew an ethicist in their daily lives, maybe people would actually have some understanding of ethics, even if they only did it grudgingly.
