I have seen a startup proposing a filter the reinject used water from the sink to the toilets or to the garden. Great idea, but very expensive, as you need to redo the entire pipe network of your house

Same protocols, different UI.
Of course then we would need to relearn to wash our vegetables before eating. Maybe why the startup didnt succeed ?
