One easy thing that you can do is take a Ziploc bag and fill it about halfway up with pebbles. Put this in the tank of your toilet to raise the water level, so you use less water with each flush. If you want to save even more money, you can replace your high water volume toilet with a model that uses significantly less water.

While you are waiting for the water to heat up when you take a shower, try catching the water in a bucket to use to water your plants or even your pets.

Checking for leaks in your toilet is also easy and you can lose more water every month than you think if your toilet leaks. Put some food coloring into the tank and if you come back a while later and the coloring shows up in the bowl, you have a leak.

Saving water is also easy in the kitchen. Washing dishes by hand is the best way to get it done, but often people use more water than they have to by leaving the water running for rinsing purposes. If you have two sinks, fill one up with rinse water and the other with soap water. Even better, if you have a spray hose attached to your sink, use that in short bursts instead.

If you have to defrost food from the freezer, you should do this by setting the item in the refrigerator for a while or by using the defrost feature of your microwave.

Outside, if you have a swimming pool, you can buy a cover for your pool which will reduce the amount of pool water that you lose to evaporation each summer.

When you water your lawn, it is best to do it in the early morning before the temperature rises. Watering in the afternoon when it is hot is wasteful, since much of the water that you use will evaporate before it is absorbed into the ground. Additionally, you should avoid watering your lawn on windy days. You can also use a screwdriver and push it down into your lawn to test how much water is in the soil. If it goes down easily, you can skip watering for the day.
