Our water tower just got a paint job

How do water towers work up there? Are there heaters in them? Just wondering how it stays liquid

Thermal mass and circulation.

Volume and constant flow, just a guess.

I asked on facebook (where this pic was posted) to see if anyone knew and this seems to be the general consensus. Still seems odd though, there would not really be that much flow at night when most people are sleeping. Though I guess the treatment process may warm it up too, not sure how long it sits inside the treatment building but it's probably fully heated. So when it goes in the tower it may be much warmer than when it was in the river. The tower may be very well insulated to. I don't imagine it's just tin metal, it's probably multi layer like a hot water tank.

Something I never really thought of till it was mentioned. -50's can freeze water pretty fast.
