Effective last Friday, October 9,
2009:

"The on-site storage and/or beneficial use of rooftop or guzzler collected rainwater is not subject to the permit process of RCW 90.03."

For a long time, there has been a lack of clarity from the Department of Ecology as to whether collection of rooftop rainwater was subject to permitting as a "taking" of waters of the State. This is a tremendous step in favor of all of the hard work we do to reduce potable water consumption in the built environment.
