[Tagging] How to tag a cistern?

Speaking of cisterns, Does this notion of "cistern are reservoirs" cover fire cisterns? 

In most urban and suburban areas of Japan, there are underground hydrants, but there are a lot of fire cisterns as well out here in rural Japan. The fire trucks carry a snorkel. I assume this is an old system (some look 50 years old), but there are tons of them - is there a fire hydrant-esque version? We're talking 2-3m concrete boxes with fireman only access through a manhole lid for the snorkel. 

The concrete boxes are often above ground and in bothersome positions (right next to the road), and labeled as a fire cistern on their road sign, as opposed to hydrant. 

I looked up the emergency=fire hydrant, and the page mentioned "pond", but there is still some kind of hydrant that is there as an attachment for the hose, whereas the cistern is merely a box with a lid. 

Maybe adding a value to:


would be appropriate, so they are included in the hydrant system (as opposed to reservoir), where they seem to belong - or is this the case where it would get both tags?

Interested in how you'd tag it to be part of the hydrant system.
