Anatomy Of A Greywater Workshop

This is the overview of a greywater workshop which took place in Benicia last Saturday.
9:00am Greywater basics in the garage classroom
The leaders, Natalie and Brian, speak for half an hour on the virtues and uses of greywater. They introduce the Laundry to Landscape (L2L) system that we are about to install today.
Digging the delivery basins close to fruit trees.
 
4 inch perforated plastic drain pipe is cut to length. These will act as mulch shields to create an air gap between delivery pipe end and tree chips. The chips allow greywater to disperse into a larger below surface area.
The blue pipe is Blu-lock one inch tubing. This more robust pipe transitions into regular one inch vinyl as it snakes down the slope (cost saving). The meandering is to calm the flow and so produce a more even distribution at each port.
 
The straight drain with 'tee' end = roof water into swale
Noon, and that important part of the install called Lunch.






Brian demonstrating how to test and calibrate the system with hose
 The half inch delivery pipe tees off the one inch main and is terminated with a valve to adjust the flow into each individual mulch shield regardless of position in the system.
Needs more tree chips and a cap to complete
Unfortunately I don't have any photos of the plumbing around the actual washer inside the house. A three port valve allows the option of diverting the discharge to sewer or garden. A vent is installed at the highest point to prevent water syphoning back.
Please check out Greywater action's website
You might especially like this page regarding the L2L system because this is just what we have inside the house.
The workshop was completed just after 2pm.
At an average of one load per day this family of four will be directing about 300 gallons of water to 8 young fruit trees every week.

New Website

We send all good wishes to this useful new addition to the local media and celebrate its enormous potential to create abundance for all.
