for a sustainable water future

Greywater Design and Installation Workshop, SUNDAY, July 13, 2014 from 10am – 12:30pm at L.A. Eco-Village

Learn how to install the popular “laundry to landscape” (L2L) greywater system in this design workshop.

Laundry to landscape greywater systems are simple, affordable, and easy to maintain. With your own L2L system you can irrigate your landscape each time you do laundry, saving you water, time, and resources. Experienced instructors will lead you step-by-step through the design process, tailoring a system to fit your home. This system is legal to install without a permit, just follow 12 basic guidelines you’ll learn about in class.


  • How to design a system for your home and landscape
