Best new strategy: I started flushing the toilet using a bucket of water from the shower. This is so simple! During my shower, I simply place a bucket in the shower to catch the run-off. Then, the next time I'm flushing the toilet, I pour the bucket of water into the toilet bowl. Done!
I started the month following the instructions of some websites which tell you to flush the toilet, then pour the bucket of water into the back storage basin. Totally unnessary and too many extra steps! Instead, you can pour the bucket (a standard bucket is exactly the right size) directly into the bowl, you don't have to flush the toilet since the gravity of the water initiates the flushing action on its own. Simple!
It's not exactly glamorous, but really easy and quickly became a habit.
Don't forget that being a vegetarian is one the best ways to save water - consumption of meat is an extraordinary waste of water!
