Free Portland Greywater Workshop Series

15th July 2017 @ 6:30 pm

Greywater Events in Portland, Oregon this Summer!

Save water this summer while keeping your garden green! Greywater, gently used water from sinks, showers, and washing machines, is an excellent source of irrigation water. Learn how you can tap into this resource at one of our upcoming workshops.

Depave, Recode, and Greywater Action, with the generous support from East and West Multnomah Soil & Water Conservation Districts, will offer a fun and educational series of workshops to help you reuse water to irrigate your landscape.

Sign up for a workshop today!

(Priority seating will be given to residents of Multnomah County. People outside of the county are welcome to sign up on the waiting list and we’ll open up extra seats to you soon.)
