Seasonal maintenance

I heard some banging when I was near the Rensselaer water tower yesterday and then noticed a man at the top.

I was lucky enough to encounter a city official who told me that the man at heights was doing seasonal maintenance. The water tank has anodes to prevent corrosion, but they have to be taken out during the winter to prevent them from freezing. I do not claim to understand the process, but maybe this piece will make sense to you.

Providing water, which we mostly take for granted unless we live in Goodland, is a lot more complex than most of us realize.
