If It's Yellow . . .

Wee 1 (wait), Wee 2 (still wait), Wee 3 (flush!) saves you about 2/3 of the water used in your toilets - which is considerable.

Money Saved: ★★★☆☆
Not only saving on the water bill, but also in most areas the water treatment fee (drainage) which is higher.

What We’re Doing
I looked up the phrase "If it's yellow, let it mellow. If it's brown, flush it down." trying to find it's origin, but wasn't successful. Certainly not fun - especially with kids who develop the habit of NEVER flushing, resulting in sometimes stinky bathrooms and clogged toilets. And when guests come around you either need to run around and flush all your toilets first, or put up a sign in the bathroom to warn them! No fun lifestyle advantages to this one. In fact, this tip may not work for you if you have an ultra-low flush toilet - as those pretty much need all the water they use anyway just to prevent getting clogged.

A Little Humor
Ummm, I don't really think I want to do an internet search for potty humor - and I don't recall any suitable ones so I think I'll skip this one!

(added later): OK, I just remembered one that might be suitable here. This was some graffiti I once saw written on a (coed) bathroom stall. Some good public service advice:

If you sprinkle when you tinkle,
Be a sweetie, and wipe the seatie.
