Stop press! Water-saving toilets (that flush)
There's one unavoidable problem with low-flush lavatories that doesn't delight even the greenest among us: they, er, don't flush very well. I discovered this to my cost on a recent visit to a green restaurant which I won't name, because I really like the place, and wouldn't want to use anything as trivial as a toilet against them. But let's just say it put me off my lunch...
Anyway, the good news is that there's a new loo on the block called a 'High Efficiency Toilet' (HEC) that's not only green but flushes like a dream and it's been certified by the U.S. Environmental Protection Agency (EPA) under a new program called Watersense. There's some detailed info on how they tested it here, and it sounds pretty effective to me!
Furthermore, they do save a lot of water (and did you know our toilets are by far the biggest source of domestic water usage?) Under US law, toilets must not exceed 1.6 gallons per flush (gpf). High-efficiency toilets (HETs) go beyond the standard and use less than 1.3 gpf. If that sounds impressive to you, there's a list of manufacturers selling HETs here!
