As is obvious from the title, this is a somewhat technical book that is of interest mainly to people who are want to set up residential greywater systems. I have a short series on my house blog about residential greywater (http://setsuzokuya.blogspot.com/search/label/greywater), so here I'll just say that this book is full of solid information. A must read for anyone who wants to take advantage of the large amount of fairly easy to process greywater produced in their home. ( )
