Patagonia Employees’ My Footprint Series: Grow with the Flow
[Ed note: This installment comes from a local Ventura canoe paddler; someone whose time on the water has influenced their concern for water resources. Faced with a different set of problems than our previous contributor, the solution outlined below is a do-it-yourself inspiration.

It seemed simple enough to create an alternate drain line that, instead of going to the sewer system, went to a greywater system in the backyard, taking

advantage of gravity to water our hillside, and perhaps the lower section of the yard. Given wash water is accounts for a large percentage of total household water use, we’d make a large contribution to a greener backyard without any added water. What a deal!
It took us about 5 months to complete, but only because we were occasionally slow at taking whatever “the next step” of the project might be from time to time. Our greywater project was finally completed in late July of 2008. We now have an alternate drain line for our laundry that runs under the house, out the back and to a hillside. Every time we do our laundry now, we are watering a different level of the hillside’s many fruit trees and shrubs. And nearly everything we have planted there will provide us with food, too. It’s awesome!
Devin devised a great valve system (photo above) that allows us to turn on one level at a time. We simply flip a couple of switches with each laundry load and this allows us to get water to any of the four different levels on the hillside. He spent a day carefully grading the four different levels in the terraces so that the water would flow properly. This is a low pressure system that relies on gravity to disperse all of the water. If the water is allowed to sit in one place, it becomes blackwater, not graywater. Yuck!
We used 
We spent a fair amount on this project, but knowing that our hillside is now well landscaped, a source of food, and really easy to maintain, made it all worthwhile. We’re very happy with the results.
