Back in August 2011, I posted the first photo you see here, after having discovered this Eco-Flushing For Dummies toilet on the campus where I work.
The placard above the toilet explains:
- the green flush handle should be pulled up for liquid waste;
- it should be pressed down for solid waste;
- it is coated to protect against germs; and
- “For the system to work, we need your help. Please take a look at the diagram…and push the handle in the direction which best suits your needs. With your assistance, we can do our part to conserve this precious resource.”
At the time, I applauded the toilet and declared it superior to another prominent dual-flush design that, I felt, fails to make it clear what the two buttons are for:
I stand by my assertion that the two-button design is less than informative, but I do have to admit that the Eco-Flushing For Dummies toilet, while ok in a public bathroom setting, perhaps particularly appropriate on a high school or college campus where, you know, education is a thing, it may not be the best, most aesthetically-appealing choice for the home or, let’s say, an elegant restaurant.
Enter John Liow’s Half:
“Half” is an observation of how suggestive design can more intentionally encourage the use of the water-saving “half flush” function on a dual-flush toilet. The white half is designed to be smooth and inviting while the black half is sharp and offensive, encouraging conscious water usage.
