Putting Lipstick on a Poop Plant?

Driving up and down the lower Spokane River will inevitably take you past the Wastewater Treatment Plant at some point.

The Poop Plant (as I like to term it) has been undergoing expansion/construction/etc since I've been in Spokane (over a year and a half now) and I understand that they are making it more efficient/effective in cleaning up wastewater before it is returned to the river system.

That being said, it was interesting to see this new public "art" in front of the complex the other day.

I'm all for public art and sculpture but does this really do much? I understand that the "see-through" pieces blur the view of the plant a bit... but I can certainly still smell it...
