Or maybe just a poor decision to use copper? PVC's cheaper AND not eaten by acids.

In fairness, the flushless toilets can very well make sense especially in water-parched portions of the US.

However, it's quite likely that this was given the full go-ahead becuase it was "green" and good for the environment so don't question it.

Looks like the installer made the ultimate mistake however and should be responsible for the damage. It's possible the school just got scammed a bit but again, they need to do better research as there have been a number of places that have had problems with flushless systems.

Here is a really good article, funny how the plumbers unions hate them....problems cited towards end of article.

Very poor decision brought on by the giddiness of going "green". They shot from the hip and completely missed the target!

They're quest to save $100 bucks a month and thumb their noses at all their green buddies turned into a half a million dollar project. Good job green weenies. I'm sure their plans to purchase Chevy Volt's will come out soon.

My guess would be that they used copper to connect the urinals to the main waste line.

As far as the urine goes probably poor choice, certainly if the pipes were PVC it wouldn't be an issue. Having said that they may still have a problem with backups, with less water usage the potential exists that not enough water is going through the system to flush it and that includes the public system.

The philly plumbers union held up the construction of a green building there until they agreed to also install a full set of additional unused pipes.

Ah yes, it's nice to see extortion in action.

Uh. MANY places use these waterless ones now. NONE of the ones I have been in smell like pee.

Edumacated guess above seems a more likely cause. Poor engineering.
