Waterless Urinal

Our travels took us past a mall, in which I discovered another generation of waterless urinals. The general notion is that the cartridge contains a light oil that allows urine through to the drain, while blocking sewer gases just like an ordinary pipe trap.

These Falcon urinals smell not at all like the Eau de Outhouse I found in Boston’s Hynes Convention Center some years ago; I suppose there was some pushback from the end-user community…

IIRC, the Hynes restroom retrofit installed waterless drain cartridges in a standard urinal. Unfortunately, with no flush water to rinse the bowl, the urine simply dried in place with exactly the olfactory effect you’d expect.

This urinal is obviously a custom-designed hunk of ceramic technology and, according to their copious literature, whizz just slides right off and runs through the Sloan cartridges on its way to the drain. I’m not sure how all that works, but things have certainly improved… or, perhaps, the mall does maintenance much more frequently than Hynes.

Anyhow, that small dot a few inches above the cartridge seems like an aiming target. Speaking strictly as an amateur apiarist, the notion of “pee on the bee” isn’t all that attractive, but I suppose they needed some way to direct the stream away from the inlets …

  1. It is probably a bee because “pee on the fly” is used by another (litigious) company. Lady bug is next.

    Reminds me of seeing a 3 year old with both hands in the urinal next to the urinal his father was using. The toddler was determined to grab that little fly.


    1. Oh, hey – I say make it electronic. Make an LED target that changes color only if you are peeing right on it. Yeah. I think I’d charge extra for that development.

  2. Actually, bees as aiming targets have been around for quite a long time. There’s an appealing hypothesis that it’s because the Latin term for bees (apis) sounds like what people do in a urinal.

  3. The falcon company actually has a machine that simulates a pee stream of every type.
    The bee is placed at the optimum target area that will result in the least spillage.
    Not sure why a bee but I do know that bee targets were used over 100 years ago.
    The bottom line is that any decently placed target will reduce spillage in any urinal or toilet.
    Many guys need something to focus on.

    1. a machine that simulates a pee stream of every type.

      Designing that must be a real bullet point on somebody’s resume!

      But it’s certainly more repeatable than finding a dozen guys with the appropriate characteristics…

  4. I don’t know about the US, but here in Europe such targets (either color changing with temperature or just plain) have been commonplace for as long as I can remember. I don’t think I’ve ever seen a bee, but other than the all too common fly (read: it’s the brand that’s too common) I’ve also seen things like a butterfly with color-changing wings, a rose that opens its petals, and a variety of other things.

    Waterless, on the other hand… that sounds more like the kind of urinals they use at festivals.

      1. I think I’ve also seen those red drain covers that turn black when you pee on them in the US, though? I presume their primary purpose of being is to prevent larger objects from being thrown in, but because they’re somewhat sizable you could also see it as something of a game to make its color swift completely.
