Wash ALL the things!

By Aimee Whitcroft 24/09/2012 34


We all know that fresh water is going to become more and more of an issue over the coming decades.  Climate change and an ever-growing population will be placing ever more stress upon this most essential of resources, and so anything that helps to save water is, at least in my books, a Bloody Good Thinfg.

If combined with some awesome design, well, so much the better.

And so, allow me to introduce to you the Washit.

The idea behind this beautiful white box is that it washes both you and your clothing simultaneously. And it saves a bunch of water because it uses the grey water produced by your washing of yourself, to wash your clothing.

Apparently, we use 150 litres in a 15 minute shower, and 38 litres per wash cycle for a washing machine, so think of the savings over time!

It’s one of those ‘well, why didn’t _I_ think of that?’ moments :)

How does it work?

The Washit makes use of a closed plumbing system with two water pumps, three filters (organic, chemical and carbon), one heater, UV filters and a water storage unit.  While someone is having a shower, the grey water they produce is collected and passed through the filters and into the water storage unit. This water can then be used again, either for showering or for washing clothes.  The filters have indicators which show where they are intheir lifecycle.

In case of water loss, Washit can also replenish its water storage using mains water. Oh, and it’s even able to dry your clothes for you :)

Two different designs

The Washit will also come in two iterations: public and private. While essentially the same, the private Washit has the washing machine bit facing outwards, while the public version has it facing inwards, into the shower.

Now – when can I have one?

The Washit’s designers are four Turkish university students – Ahmet Burak Aktas, Salih Berk Ilhan, Adem Onalan, Burak Soylemez – and the product was begun as a university assignment, although it has since garnered the  iF Concept Design Award 2012: Hansgrohe Special Award. This year’s Hansgrohe topic was ‘my green shower pleasure’: some 150 different concepts reached the final round, and the 6 winners the prize, worth 5,000 Euros.

  • I’m on rain water supply so anything that helps save water is cool by me. unfortunately I distracted wondering why all the maintenance and clothes washing functions are illustrated with a drawning of a dude while many of the shower demos are with a real woman.

  • That is rather brilliant. Although this bit – “integrated shower head offers pleasure” – did give me cause to pause for a moment’s consideration…

  • the maintenance and clothes washing functions are illustrated with a drawing of a dude
    because the Modern Man (TM) helps with the housework!!

  • Alison – yeah, I giggled at that bit, too :) I think that’s int here because the Hansgrohe award title was ‘my green shower pleasure’…

  • Its an example of expensive sillytech- its very wanky.
    .
    what sort of city council stops its residents from using reasonable sized water tanks to utilize rain water.
    Want to improve our water usage then sensible solutions are called for, wanktank concepts are not the answer.

  • @Alison one can’t wait for others to be conscious, you can be what you want yourself to be without waiting for the answers from others.
    A great concept for teaching water conscious behaviour to children in “developed” countries would be an attachment to the water taps of a talking duck (*Mr Agua). Ideas that actually can save water and promote better habits work, not these expensive impractical technologies/concepts.

  • @Alison one can’t wait for others to be conscious, you can be what you want yourself to be without waiting for the answers from others. – not quite sure what your point is here, BDBinc – I was responding to Darcy on how long it would take your clothes to dry!

  • what sort of city council stops its residents from using reasonable sized water tanks to utilize rain water.
    Um, a city council where a large proportion of ratepayers live in high-rise accommodation and lack anywhere to erect such tanks? Perhaps not the case in most parts of NZ, but in Europe & Asia, for example, that would be the norm in highly urbanised areas.

  • BDBinc, Is there legislation preventing people from using rain water? Could you reference that please? I’m sure we’d want to put pressure on to change that sort of ridiculous thinking.

    I have two water tanks but I still have to be careful about water, especially during long dry summers, utilising “grey water” is one way to do that.

  • Strangely enough I was not talking about Asia and Europe Alison, the larger proportion of ratepayers in WGTN do not live in high rise apartments.
    Encouraging the use of water tanks to collect and store rainwater from roofs in residences in Wellington is a reasonable idea .

    Mr Cowan you can try get the WCC council to give you consent/permission for a decent sized water tank mr darcey (they have bylaws and ” stormwater issues” ) we cannot cope with any the excess water -in heavy rain we get flooding and I’m in the CBD)so us storing the water would help the storm water situation.
    Most homes in NZ CAN have a watertank and should be encouraged to do so( we manufacture them here).

  • Strangely enough, BDBinc, it wasn’t obvious that you were talking about Wellington. Aimee’s post is about an invention from an overseas competition; commenters could be from anywhere.

  • What obstacles are you specifically referring to re the installation of a residential water tank, BDB?
    According to this WCC Strategy and Policy Committee report dated 24 March 2011, WCC are supportive of rainwater harvesting at the household level for a range of reasons, including improving post earthquake resilience. However at this stage they are probably unlikely to offer a subsidy.

  • I already have a decent size water tank, thing is it’s still limited, plus I live in Hamilton so asking WCC would probably not help anyway.

    So if a solution isn’t tailored for Wellington it’s worthless?

  • Nope Alison as I said I was not referring to Asia and Europe, it was you that brought up Asia and Europe.
    Darcey a solution is a solution .

    It would work to conserve water for Wellington (NZ), and it would work for most of NZ.It works in Hamilton, its not a tailored approach.
    I think you guys just enjoy the novelty of promoting a silly flawed technology and ignore simple solutions to water conservation and the barriers to water conservation in the country where you live.

  • Possibly, we are a silly bunch.

    Or we could be thinking that the more overall solutions that exist the better and perhaps a package of approaches that take all factors into account would be best.

    But your theory is good too.

  • Hi BDBinc

    Um, could you please restrict your commenting to not insulting other people on this thread, or making conclusions regarding what people are or are not ignoring?

    Further, the post is mine (not theirs, so they’re not promoting anything), and I was pointing out it’s a wonderful piece of design, and something which I thought was quite clever. An opinion to which I am entitled :)

    At NO point has anyone here said that solutions such as water tanks etc aren’t viable alternatives (in some countries), or that the above design is exclusive of other solutions, too. Please remember, too, that this technology was not designed for or in NZ, where water is (generally) plentiful, both rain- and fresh.

  • Perhaps.
    What was it that I said insulted your mis science bloggers Amy?
    (and it was Alison that disagreed with me on watertanks as a water conserving tool)
    Water is not plentiful in all parts of NZ in summer.
    I don’t really understand why my simply disagreeing with the ideas here is insulting.
    I can see that the “washit” is not a solution.
    And I think its silly, appealing only to those desiring pleasure and novelty.Do you really just want bloggers agreeing with everything your post – can only scibloggers such as Mr Cowan be skeptical?

    And I did not insult, unless the truth is insulting or a different opinion to yours is insulting to you.

    But to end on a positive note its great to see a change in the WCC, no permit and nothing needed for a decent size water tank now( thanks for that news Carol).

  • BDBinc

    Um, I’m the only blogger on the misc.ience blog. Because it’s my blog. The other people here are commenters.

    I was merely asking you to watch your tone, and comment/reply with the same respect to other commenters as they have to you.

    You are absolutely welcome to disagree that it’s a solution, just as others are welcome to say otherwise, and that they don’t see water efficiency as something with only one solution.

    To say “I think you guys just enjoy the novelty of promoting a silly flawed technology and ignore simple solutions to water conservation and the barriers to water conservation in the country where you live.” is needlessly argumentative. It casts aspersions about other commeters feel is important, and makes assumptions about how other commenters think and what they do or do not ignore – something you cannot possibly know. As previously mentioned, this post was as much about clever _design_ as anything else, and was never a) ignoring other water efficiency methodologies or b) promoting this as the only solution to water efficiency.

    aimee (not Amy)

  • BDBinc,

    Just a quick thought – the ‘pleasure’ bit will almost certainly be a case of foreigners whose English is not quite conveying their meaning intended. Travellers in particular will be very familiar with this. I imagine it‘s meant in a very modest way, in the same sense we’d think of enjoying a hot shower.

  • Grant – yeah! Especially if it’s got some coverage, and isn’t a damp little trickle down the back of one’s neck 😛

  • Although I’d probably not call them ‘foreigners’, since they were locals in the country in which they designed it, heh 😛

  • I meant foreign to NZ, in a country where English isn’t the principle language – there’d be a better phrasing, but I’m dead tired. (My excuse, anyway…)

    It’s annoying, eh, when the hotel showers essentially have no water pressure and are really not much better than a tap!

    That sort of phrasing issue is so common in parts of Asia, for example, that it’d be a safe bet some are deliberately playing on it! :-)

  • No aimee you said I had insulted another commentator .
    So how do you find that false accusation is respectful to me.
    You didn’t like my opinion which was in disagreement with your own.
    Just make a note on the mis science blog to only let your agreeable colleagues comment on this ( a public funded) blog.
    We can’t have members of the the public disagreeing with your opinion & posts.

    (*Don’t feel bad Aimee, most of the people in the world are taken with novelty and pleasure, thats why we are in the state we are in. And you didn’t need to get upset at me for pointing it out.)

  • BDBinc,

    You wrote “You didn’t like my opinion which was in disagreement with your own.”

    Aimee can speak for herself, but best to read her words rather than make out to have said things I think, e.g.

    “You are absolutely welcome to disagree that it’s a solution, just as others are welcome to say otherwise,”

    (She related that she was concerned about your tone, not that you disagreed or not.)

  • BDBinc, I don’t see Aimee stopping you from commenting here. I consider myself a member of the public and as such free to agree/disagree with Aimee or anyone else here.

    You basically came in and immediately started assuming what everyone else thought about all things water conservation related. I found that the most insulting thing.

    So notes about your tone are quite appropriate.
    Had you phrased your concerns differently we could now have been discussing the relative merits of each approach and how they fit into the local and world wide picture instead of bickering about whose been insulted or not and such.
    But there we are.

  • Strangely enough I was not talking about Asia and Europe Alison, the larger proportion of ratepayers in WGTN do not live in high rise apartments.
    BDBinc – until you said this, there was no way that anyone could tell you were talking about Wellington (or NZ in general). I had suggested that household water tanks were perhaps not a workable solution in highly urbanized areas in Asia & Europe, where many live in high rise apartment blocks. I was not disagreeing that such tanks were not a workable solution in NZ. However, in some parts of the world technologies such as the one Aimee’s talking about here might be part of water conservation efforts.

    The fact that we find a particular piece of technology quite ingenious doesn’t mean we don’t care about other issues.

  • Grant I was clearly told I insulted commentators.

    Darcey (no you are a blogger here & not a member of the public ), if I had said this in my disagreement with you all : Young university man has a shower in his clothes one day and thinks to himself ” that act washed my clothes while I showered so I’ll combine a water filter, a washing machine and a shower” .
    All sober wet and soggy he sells his flawed concept to someone else.
    Its not ingenious.
    Unlike showering with clothes on , which does much the same thing this concept does without sucking energy and extra expense( if it had been solar powered I would not have voiced as much disagreement with the concept.) Its not ingenious.
    As I said before you guys like this concept which is in fact silly, I am disagreeing with the concept and your opinions on the concept and your accusations that In my disagreeing with you I insult you. So If you are disagreed with, you find the “tone” of disagreement insulting.
    I know you guys care about other issues Alison, caring was never discussed.

  • ok, separate the shower and washing machine. Now the grey water is collected and used for other applications, including washing clothes. Still object?

    Please, if you can’t spell my name correctly, use copy paste from one of my comments.

  • You also imply the main nature of your problem with this is the extra energy used. This did not figure in any of your previous comments. Any other issues you have with it? we can discuss those rather than dwelling on your attitude.

  • Yes it did figure into my comments Mr Darcy Cowan as “silly” encompasses this concept perfectly.
    Haha there are so many things wrong with it, but its been made clear by this blog if I enlighten you further you will just insult me by making false accusations (which none of you has backed up). I don’t want to insult you by disagreement.
    You all continue to think its ingenious.
    P.S Sorry I am about the spelling errors.
    And to answer your first comment Darcy the reason why they used a naked colorized woman and the specific wording of the “shower head for pleasure” is to sell it using sex. (Maybe if it didn’t distract you we would be on the same page.)

  • Silly also encompasses the colour, have a problem with the colour do you?

    I get the sex sells thing, but I don’t think it has anything to do with your attitude.
    I’ve tried a couple of times to get you to discuss this reasonably, this having failed I give up. Congrats.
