Don't have drought, thankfully. I don't even pay utilities separately, but even so, I am very aware of how much I use. I use Fluorescent bulbs, and if LEDS comes down a bit more I will use them instead wherever I can.
I use tank water from changes to water plants and if that doesn't use it all, I'll use it to flush the toilet too. I try to use as much of it twice as I can. I shower with a hand held and when I'm not rinsing soap off, I let the rest of the water run into a bucket which I use the same way.
And it's just one reason I never wanted an RO filter.. not that I can have one anyway, landlord won't allow it, but they waste so much water in the process.
