I and a small group af aspiring engineers have a project for school that could involve the re-design/re-engineering of an existing concept, coming up with something new, basically anything that could be theoretically brought to realization with minimal engineering skills. lol

So for example, the water you use in your shower should be recycled for the toilet. No point in dumping my waste in water that is cleaning and drinkable.
That is already a done deal, it's called Gray water flushing, where you have a tank in the basement, say 100 gallons or more, and the water from the shower or the bathtub is diverted there instead of going directly to the drain but instead going to the toilets. This has been shown to give at least a 20% decrease in water consumed.
The project is not as simple as I make it sound but very easy in terms of plumbing.
