Greywater

We also have our Greywater Packet available here!

We love living in a healthy environment and want to keep that way for generations to come. We are experts in water conservation and using our precious water resources the best ways possible. Greywater is a great source of reusable water. This is waste water that is captured from sinks, showers, and washing machines and has been legalized for irrigation use in California since 2009. Most of these systems are gravity flow and very simple to install into a new or existing home. They are great ways to water a fruit orchard without paying for extra water costs.

Mulch Basin

Mulch Basins

One inch flexible tubing is used to move graywater into the garden. An outlet is placed near the root zones of each plant to be watered.

Each outlet basin is backfilled with mulch as a filter media for the graywater to infiltrate around the root zone.
