Want to save the planet and money? How about just money? Either way, it’s a smart idea to get your water consumption in check. Wiki How offers these tips (plus ten more for outdoor water usage):

Fit a water meter. By fitting a water meter you can raise your awareness of how much water you’re using and consequently reduce your intake.

Catch the cold water that comes out of the faucet/tap while you are waiting for the hot water. Use it to water plants or pour into your toilet reservoir after flushing. Water from a hot water tank may have more sediment or rust than water from the cold water tank, but is otherwise suitable for drinking.

Check your plumbing for leaks, especially leaking toilets and faucets. Fix anything you find is leaking. A silent toilet leak could waste from 30 to 500 gallons every day!

Take shorter showers. Catch the cold water when the shower is warming up and put it to use elsewhere. By taking a bath you are using up to 100 liters of water! Showering will generally use less than a third of this amount.

Turn the faucet/tap off when brushing teeth or shaving.

Wait until you have a full load of clothes before you wash a load. Don't wash a load of clothes just because you want to wear the same pair of pants the next day. Also, be sure to use the economy mode.

Use waste water or gray water from washing machines or dish washing on the garden. If possible, hook up a hose to the outlet on your machine to send the water outside onto your garden. When hand-washing dishes, if you rinse the dishes over a plastic bin, empty the bin into your garden.

Convert your toilet to a low-flush toilet. Don't flush the toilet all the time and/or use the half flush button with dual-flush toilet. You can also buy a dual flush conversion kit to turn your water guzzling toilet into a water saver you can be proud of. Search the web for devices like Selectaflush and twoflush they both will work great and save you lots of money.
