The webinars will be held live from 4-5pm on Wednesdays (dates below).

Cost: Fee for the series is $30 to $100 sliding-scale*.

*Wondering what sliding-scale means? A sliding-scale fee means that participants choose the amount to pay along the scale (between $30 and $100). People who can afford to pay more help subsidize people who can’t afford it. This helps us keep our workshops affordable to more people. We thank you for paying as high as you are able to on the scale.

Branched Drain Systems and Greywater in Arid Climates

  • December 2nd

A gravity-based, branched drain system delivers shower or sink water to the plants via a set of rigid, branching pipes. This system requires the landscape to be lower than the plumbing, and is best suited to irrigate large plants, like trees and shrubs. Though time consuming to install, once finished a branched drain system is extremely robust; it requires no energy to operate, has no moving parts to break, and needs very little maintenance. This presentation will also cover best practices for greywater irrigation in an arid climate.

Presenter Nicholas Holmes: Nicholas is an ecological designer-builder with degrees in architecture and sustainable development from Cal Poly SLO. Nicholas installs greywater systems in Joshua Tree and surrounding desert areas and is the co-founder and director of The Nourishing Tree, a small mixed-use center for healthy and sustainable living.

This presentation will focus on fruit trees of Southern California, but the principals and greywater systems information is applicable to a wide geographic region.

Presenter Ty Teissere: Ty specializes in backyard orchard care, from building the soil life to pruning the canopy, and the irrigation systems in between. He is a Greywater Action instructor and installer as well as a a certified arborist (#WE-10547-A), rainwater harvester (Watershed Management Group), and has his horticulture certificate from Long Beach City College.
