I've heard people say that "Homeland Security" recommends separating your utility data for water and wastewater treatment plants from the rest of your system's model. (I put DHS in quotes because I cannot find a source for this claim.) A cursory Google search isn't turning up anything useful, so I thought I'd ask how others handle the storage and sharing of their utility data. Do you share any/all of your system data with the public? Are treatment plants separated from the rest of the system? Appreciate any information - including opinions - that the community would like to share.
