This Old House has a green issue out this month. They've done a good job explaining some basic energy concepts that I understand overall but need a little more clarification of how exactly they works. More importantly how they could be applied to our project if at all. An example of this would be a graywater system. To cut straight to the essence of this system- your house has potable water being generated into the home and non-potable being generated and pushed out of the home through a sewer line. The basis of a graywater system is to further separate the non-potable water into 2 categories: graywater and blackwater. Graywater is bathroom sink, tub and shower, and washing machine water and blackwater would be toilet, dishwasher and kitchen sink water. 2 separate water lines would be established within the home so that blackwater would not cross paths with graywater. Blackwater goes to the main sewer line as usual and graywater is collected into a surge tank. The main reuse for graywater is (subterranean) irrigation which is legal in almost every state. Since we will have native landscaping would we really need this elaborate system for watering a landscape? Check out a full overview of graywater systems at the Link.
