I have a pee pail which sits on the toilet ,..all daytime pee is collected....only one flush at night before bed if needed, however if equal amount of water ( recycled ) is added it is great fertilizer for those dry plants that need a drink Same at night...pee pail beside the bed...any night pee goes in and is also used as fertilizer.
And all those leaves people clean up in their yards...put them back on the ground around plants as mulch to hold humidity
or compost them.
Do whatever you can to reuse water as well
