Well, so glad you asked! This happens to be *exactly* the sort of situation the
Builder's Greywater Guide was written for.
Systematic change in regulation is a time consuming process.The Builder's Guide is designed to help save time on this. It is basically an infomercial targeted at regulators and policy makers, to help them understand greywater and be comfortable regulating it in a common sense way. (A number of people have weighed their time against the cost of the book and just bought one for their local building department...one guy bought about 50 and had us send them to a whole bunch of regulators and policy makers).
The same
model greywater codethat is in the book is also posted in our greywater policy center, along with a bunch more info.
You could also suggest he call Larry Fay, head of environmental health in SB County, who used to work in Washington.
Yours,
