Dutch designer Sam van Veluw has developed a new way to answer the call of nature at outdoor events and venues. After a long search for a public restroom at a music concert one evening, he came up with the concept of strapping a waterless urinal onto a tree. These would be simple to install and can relieve the pressure on porta-potties (we had to use the pun) at public events. Its practical application may be questionable, but it is a refreshing approach to what can be a pressing problem.

Although at first glance this concept does not seem to be fair for women’s needs, the good news is that the P-Tree can reduce the queue at the porta-pottie. The inventor suggests that it can be hooked up to a central sewer system, but an onsite infiltration system would be a great way to safely dispose of the liquid and nourish the trees with nitrogen at the same time! This would reduce the chemical and waste processing involved at public events. As for using the P-Tree at your next happening – we suggest looking into your local indecent exposure laws first.

    When guys see the P-Tree at an event, it’s obvious what its purpose is. The message I get is that “It’s okay to pee here.” Without the P-Tree, I would not be as likely to just pee on a tree and would look for a port-a-potty. Hence the P-Tree will reduce the lines at the port-a-potties by redirecting males elsewhere.

    When suddenly the need to pee arises outdoors and I’m not near a bathroom, I’m more concerned with potentially getting hassled by the cops than I am with modesty. It’s not a big deal to see a man pee in public, and I don’t see why so many people are hung up on privacy. Skip the temporary walls. I don’t think most guys would care about using the P-Tree as is as long as they won’t get arrested for doing so.

    Answer: not available that I know of…
    Question: where do I buy these

    Where do you buy one? Would be very useful in a watch tower and route the tubing all the way to the ground.

    Too much fertilizing will kill the plants though. I am more a pessimist on this one… people will just fill it with garbage. Now the challenge is… make a female version!

    This is a great idea for anywhere! All you have to do is to put up a temporary wall. Two posts and some cloth or tarp would do it. Much easier to take down and move than a whole port-o-pottie, right?

    Turns out urine is mostly sterile and an excellent fertilizer as well, filling up those undiluted jugs of urine and/or a truck would be great too. This reduces a lot of the energy requirements of waste-water treatment plants.

    Good idea. But I think they should redesign the urinal so that people don’t see your pen!$.

    This is really good for a country like India.(at least that is what I think)

    This is stupid. If people are going to see you peeing anyway, just skip the strap on urinal and pee on the side of the tree…
