You answered your own question.
Urine is pretty much sterile so how can it be dirty? unless your infected![]()
Save water ... why? We are an island surrounded by water not a desert; plus we have plenty of rain.
Perhaps install one of those eco-toilets, or whatever they are called, which only fluch a small amount for urine but flush the full cistern of water for poo.
Our toilet takes an age to refill so we quite often have a "Dont flush!" shout if someone going in and you might need a wee in the next 15-20 minutes.
Otherwise we flush away.
Mind you I can hold my pee like a camel. If I have to, I can go from morning to the next day without needing a ****.
No, I flush after each and every usage. However, to offset the water usage I like to think of an African family who live within walking distance of water but likes the ease and comfort of having some aid agency deliver it for free.

Do you know how hard it is to turn sea water into drinkable water lol.. hard.
If the governments code for sustainable homes 2016 does come into force we are going to see much more of water saving features in homes as currently our water usage is miles off what there targeting.
