Events: Laundry-to-Landscape Greywater Workshop

October 21, 2023
9:00AM - 4:00PM


Presented by Greywater Corps x Sustainable Claremont

This full-day workshop will take you through the design, plumbing, and installation of a laundry-to-landscape greywater system. Participation is strongly encouraged for this hands-on, start-to-finish workshop, so come prepared to roll up your sleeves and break a sweat!

Building a greywater system in one day requires a team effort, and there’s no better way to learn the intricacies of L2L systems, from plumbing the washing machine to building the irrigation system, than getting your hands dirty and doing it yourself.

Greywater re-use is one of the best tools we have against drought, climate change and urban heat. Given the ongoing water and climate crisis, we believe this work is more important than ever. Join us to see what it's all about!

The workshop will cover everything you need to know to install your own laundry-to-landscape greywater system with a minimum of tools and experience.

Topics covered will include:

  • Greywater Basics

  • System Calculations & Design

  • Irrigation & Plumbing Design

  • Irrigation & Plumbing Installation

  • Testing & Tuning

  • System Documentation

Saturday, October 21, 2023, 9am to 4pm

The workshop will take place at a private residence in Claremont, CA*
