One Liter Limited

1ℓimit faucet looks more like an elegant test tube inverted on top of a tap. The glass tube holds exactly one liter of water, sufficient for a quick handwash. The theory being that we waste almost six liters of water and use only one, while washing hands. Once the stored one-liter is used up, you have to turn-off the tap till the next one liter fills up the tube. A cumbersome rationing process that will hopefully drive home the point of conservation!

    Very cool concept. Beautiful aesthetic. Functionally I can see this getting kind of frustrating though. Otherwise, nice!

    How does the water in the tube stay warm/hot for those of us who don’t wash our hands with cold (or room temp.) water?
    Love that it subconsciously promotes water conservation in such a stylish and beautiful way, though.

    yes! Exactly the kind of thinking we need!

    is there and off switch on the one litre limit… love the design and the concept but think it would sometimes not benefit…

    How dou you manage the airflow inside the thing?

      with a hole?

      • tt is a tool says:

        What prevents this water coming from said hole? The water pressure doesn't just magically disappear when you feel like it. I am sure there is a elegant way but to pretend "a hole" is an appropriate answer is just pathetic.

    This is really pretty. However, I'd like to see it in conjunction with a motion sensor instead of a handle, and a soap dispenser figured in there some where to get the most out of that liter. This seems like it thrives on efficiency as well as conservation so making sure all the required parts are right there would make it more effective.

  • I would replace all of my faucets with this one in a heartbeat. My boyfriend and I love the idea!

    Is it for a public restroom?
    I think that the person who finished to use the faucet will not move the lever to "close" position (because water doesn't flow from the faucet after using 1litre).
    So, the next person have to move the lever to "close" position, and wait to fill up, and then move the lever to the "open" position.

    IMO, it's a kind of time-consuming task, and It will prevent people to use intuitively.

    • Try B says:

      I agree. I'd hate to be the guy waiting for my turn to wash my hand. I will need to wait for it to fill up. imagine this in restroom near the cinema…

      but great idea to use elsewhere … home?

    • Toast says:

      It wouldn't take much to put in a control that snaps the lever back to the off position when the water is done flowing.

    The reason people waste a lot of the water is letting it get warm. I see this as dumping a liter of room temp water on your hands at best. Unless this was used in conjunction with some type of point of use water heating system.

    Really? I just washed my hands, no watersaving faucet, with a reasonable flow and didn't use even a liter. Just think about a glass test tube, how fragile i is. Nice concept, beatutiful render, non practical idea.

  • nooooooooo says:

    Shaving? How does it know if you want hot or cold? Sorry, this is a dumb idea.

    • Toast says:

      You're dumb. If you look at the pictures, you can see that the placement of this faucet would be in a public restroom. Who shaves in the restroom? As for temperature, it wouldn't take much to put in a point of use water heater. You shouldn't be washing your hands with cold water anyway.

      My suggestion as an improvement, remove the handle, and make it activated by motion sensor, both to improve the form factor as well as to remove the contact between washer/faucet, so as to minimize spread of germs.
