I've been doing a bit of work with ReCode Oregon (recodeoregon.net)
and figured you might be interested in this...
Over the past year, Recode, Cascadia Green Building Council,
Willamette Riverkeeper and many others have been organizing to
legalize the exterior reuse of graywater.
As a result of this organizing, the Oregon House Energy and
Environment Committee recently introduced HB 2080. This bill, which
will be decided in the 2009 legislative session, would remove barriers
to graywater reuse and instruct the Department of Environmental
Quality to make rules regulating the use of graywater. The text of
the bill is here - http://recode.ws/images/e/ea/HB_2080.pdf
