Why Is This Water Tower Rusting on 240 in Fairhaven?

As I was driving into work today, something caught my eye that I just had to make light of. You've probably seen it a hundred times and never really given any notice to it, yet its in plain sight.

Especially if you drive the Fairhaven connector road, the famous strip that is Mass Route 240. Coming from the highway, right in front of the car dealership on the right is a rusting piece of history, an old water tower, or at least thats what it looks like. Looks as if it hasn't been touched in years.

More like an eyesore rather than a piece of Fairhaven's past. If its still there, why not paint it or make it look better? Its rusting and need of some TLC. If not, then why keep it?
