The secret to saving water is a synthesis of good practices and good design. Keep an eye on the the TreeHugger archives for the latest methods and technologies.
Toilets
- Dual-flush options are available from Caroma, and numerous others. This Argentine toilet design lets the sink water do the flushing.

Showerheads
Some showerheads that TreeHugger has investigated include: the Neco, the Tiara shower for two (or one, if you’d like), Bricor offers 1 gallon-per-minute heads, the Aqua Helix squeezes out an impressive .5 gallons per minute, and Real Goods has an affordable unit with a "pause" button. And if you have a tendency to lose yourself in the moment, a shower timer might also be a good idea.
Water heating
Point of use water heaters save water by delivering hot water almost immediately rather than making you wait for it while the tap runs. Some even use microwaves, and this Thermostatic fixture cuts the waiting time and looks sharp in the process. More solid tips on greener water heating can be found here.
Purifying water
See some of the neat developments in water purification for third world communities, including the LifeStraw, the UV Tube, the coffeground water filter. It has even been suggested to make water filters from old tires. Before he segwayed into transportation, Dean Kamen developed a water purifier: "If you could take all the diseases you could name, 80 percent would be wiped out if you just gave people clean water." Hydro-Dis is a new three-stage disinfection system from Australia; Julie Frost, an Australian student, developed a clever pasteurization tool.

Bottled water
If you have your doubts about the harm of everyday bottled water, wait until you see our coverage of strange waters: water that makes you skinny, water for dogs, water that is sung to and infused with good intentions, and water with gold in it. Some bottled waters like Biota and Jivita are now using containers made from cornstarch, also known as polylactic acid (PLA). While these are non-petroleum products and are, in theory biodegradable, they are not recyclable and most likely will never break down in your backyard compost pile. Some companies like Ethos and HtoO are doing constructive things with their profits, but they still are responsible for the many ecological impacts of bottled water.
