Graywater Resources

REGULATIONS

Greywater from washing machines directed into mulched basins does not require a permit in Ventura County, as long as the installer follows some standards developed by State of CA, and revised by the County of Ventura (see the GW-1 guidelines).  Greywater from bathroom sinks, tubs and showers can be redirected into your landscape where is a permit is required, with design considerations recently developed by the County of Ventura  (see GW-2 guidelines).  Reuse of greywater from kitchen sinks is currently prohibited.

Our local contact is Jim MacDonald, director of  Ventura County Building and Safety Division (654-2787 or Jim.MacDonald@Ventura.org).  Jim wrote an article on greywater for the Ventura County Star that is a good overview of GW-1 standards (where no permit is required) and available here:  http://www.vcstar.com/lifestyle/how-to-use-laundry-gray-water-for-landscaping

 The County typically does several greywater workshops throughout the year.  Here are links to websites with more info:
