Part 1 of 4: Conserving indoor water in general

 Save water from your taps.
 Turn the faucet/tap off while you are brushing your teeth, shaving, washing your hands, doing dishes, and so on. Turn the tap off when you shower, too. Get wet, then turn off the water while you soap up. Turn it back on for long enough to rinse. Look for a twist valve that installs behind your shower head to keepthe water temperature where you set it while the water is off.

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

Part 2 of 4: Conserving water in the bathroom

 Install low-flow shower heads and faucets or faucet aerators.
 Low-flow devices are inexpensive ($10-$20 for a shower head and less than $5 for a faucet aerator). Most simply screw into place (you may need an adjustable wrench), and good, current units maintain the pressure and feel of the flow while using as little as half as much water as conventional units.

 Take shorter showers.
 Take a timer, clock, or stopwatch into the bathroom with you and challenge yourself to cut down your showering time. You could even play music while in the shower and challenge yourself to cut down the number of songs it takes you.  the shower, or turn off the shower while you shave.

• Take showers rather than baths. Bytaking a bath, you are using up to 100 liters of water! Showering will generally use less than a third of this amount. See the water use table below.
• Install a valve that fits just behind the shower head. These valves are inexpensive and simply screw into place. Turn the water on for long enough to get wet. Then, use the valve to turn the water off while preserving the temperature of the water while you soap up. Turn the water on again to rinse.

 Use waste water or gray water from the bath, 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. To re-use bathwater use a hand-operated Syphon Pump. When hand-washing dishes, rinse the dishes into a container, and empty the container into your garden.

 Convert your toilet to low flush.
 Place a plastic bottle of water in the tank to displace some of the water used for each flush. Weigh the bottle down with pebbles or sand, if necessary. Or, try ordering a 'save-a-flush' or 'hippo' from your local water board

 Get or create a dual-flush toilet.
 This is basically a toilet that flushes a smaller amount of water for when you pee and more water for pooping, thereby saving water. Use the half flush button with a 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 work well and save money.

 Make sure to use your toilet appropriately.
 Don't flush every time. Remember; "If it's yellow let it mellow, if it's brown flush it down." Also, don't use your toilet as a trash can. Each time you flush you use up to 9 liters of clean water, which is a lot of unnecessary waste!

Part 3 of 4: Conserving water in the laundry and kitchen

 Replace your clothes washing machine with a high-efficiency washer.
 Old-style top-loading washers use 40 to 45 gallons per load, and the average family of four runs 300 loads per year. High-efficiency washers, typically front-loading, use only 15 to 30 gallons per load. This works out to a savings of 11,400 to 34,000 liters (3000 to 9000 gallons) per year.

 Wash full laundry or dish loads.
 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! When washing your clothes be sure to use the economy mode and this will save you both water and electricity! This goes for dishwashers, too. Load the dishwasher full but not overly full.

 Do less laundry.
 For this, you and your family will have to produce less laundry, but you will save time and wear and tear on your fabrics, as well. Unless your clothes are obviously dirty or smell bad there is really no point in washing them

 Install a water meter.
 You might be very surprised to find out how much water you are actually using. By installing a water meter you can raise your awareness and consequently reduce your water intake.

 Cover your swimming pool.
 This helps to prevent evaporation. In some places, emptying and refilling a pool is under severe restrictions, or even banned, so preserving this precious resource is crucial.

 Time your water usage.
 Put a timer on your sprinkler and outdoor faucets/taps. Look for inexpensive, automatic timers that screw between the hose and the hose bib, or install a programmable timer on your sprinkler or drip system. An automatic timer can also help you water at times of day when the water can best be absorbed.

Part 4 of 4: Conserving water when gardening

 Care for your lawn in a more water-efficient manner.
 Only water the areas that need it, and only when there has not been enough rain. Use a trigger nozzle on your house or use a watering can to save water. You can also, catch the rain  and use it for watering your plants, lawn or garden.

 Grow grass appropriately.
 Don't mow your lawn too short. Raise the height of your mower blade, or simply let it grow a bit longer between mowing. This way you won't have to use as much water
