Treating greaywater

Continuing our home-reinvention goal, I should add one of these greywater treatment system to all the other environmentally-oriented changes we’re trying to make at home. Now that we’ve gone with a 100% renewable power supplier the two things I’m feeling bad about are wasting water and burning gas (real gas, not American petrol). We have a gas powered boiler for hot water and heating. Not sure what the options are for replacing that. This system might help with the water thing.
