One simple way to save water is with a dual flush toilet. This one, the “Persuade” by Kohler, has a standard flush of 1.6 gallons plus an optional flush of 0.8 gallons — cutting water use in half.
To word this delicately, for most of our flushes, the 0.8 gallon option will be adequate. This will save a large amount of water annually. List price for the white one is about $360. Not too bad.
If you are serious about saving water, want a toilet that works, looks sleek and is affordable, please look into Caroma Dual Flush toilets. Caroma, an Australian company, invented the 2 button Dual Flush technology in the 80’s and is the worlds leading manufacturer with more models listed on EPA’s list of WaterSense labeled toilets than any other manufacturer. Caroma toilets offer a patented dual flush technology consisting of a 0.8 Gal flush for liquid waste and a 1.6 Gal flush for solids. On an average of 5 uses a day (4 liquid/ 1 solid) a Caroma Dual Flush toilet uses an average of 0.96 gallons per flush. The new Sydney Smart uses only 1.28 and 0.8 gpf, that is an average of 0.89 gallons per flush. This is the lowest water consumption of any toilet available in the US. Also, with a full 3.5″ trapway, these toilets virtually never clog. All of Caroma™’s toilets are on the list of WaterSense labeled HET’s http://www.epa.gov/watersense/pp/find_het.htm and also qualify for several toilet rebate programs available in the US.

Thanks, Andrea. More information is ALWAYS better. I checked and the Caroma toilets are readily available from many local plumbing suppliers (even here in Eugene, Oregon).
