Project #1: Sunken vegetable garden

Installation Date: October 10, 2013

Location: Private residence, E Southern Ave and S 48th St, Phoenix

Workshop Leader(s): Ryan Wood

Number of Co-op Volunteers: 16

The homeowner wanted to grow vegetables in a desert-friendly fashion. To maximize water retention and minimize evaporation, 50 square feet of sunken vegetable beds were installed.

Project #2: Laundry to Landscape (L2L) greywater reuse

Installation Date: October 10, 2013

Workshop Leader(s): Ryan Wood

Number of Co-op Volunteers: 16

The homeowner also wanted to capture greywater from her washing machine and reuse it to water two fruit trees and several understory plants.

A pressurized Laundry to Landscape (L2L) system with polytubing and emitters was installed to convey the greywater to earthworks surrounding the fruit trees. The total annual output of this system is 3120 gallons.


The sunken vegetable bed is desert friendly. It naturally harvests water runoff and retains moisture from irrigation in the planting area. Because the bed is sunken, there is less surface area exposed to our harsh sunlight and heat which causes very high evaporation rates. Organic matter naturally collects in this sunken area which mulches the bed and builds soil over time, all with less work on the part of the homeowner.

With the addition of a Laundry to Landscape greywater implementation, 3120 gallons of laundry greywater is being used for the benefit of watering two fruit trees and fifteen understory plants, instead of being directed into the sewer system. By sinking this water into the ground instead of sending it down the sewer system, the homeowner can get multiple uses out of the same water and rehydrate her property.
