During last week’s dash to the mountains, I noticed the waterless urinals in Pisgah National Forest and I actually started to feel a little guilty about expressing skepticism over their use in so-called ‘green schools.’

But guess what:

Once a hallmark of UNC’s sustainability initiative, the water-free urinals on campus will eventually be substituted with ultra-low-flush devices, said Carolyn Elfland, associate vice chancellor of campus services.

Elfland said the urinals are being replaced because the University has experienced “some significant problems” with them.

The Falcon Waterfree urinals installed across campus tend to block the plumbing system at times, creating a foul smell, Elfland said.

“When we discovered the issue of deposits in the urinals, it was pretty alarming, because it could lead to big plumbing issues wherever they’re installed,” Elfland said.

I don’t feel so guilty now.
