This morning, as I took my shower, I thought about how I was going to set up my grey water system this year.
For the last two years I have collected the water from showers and used it for watering the gardens. It is a wonderful source of water during the summer dry spells that we are are now having. Originally I used a watering can to transport the water from the rain barrel to the plants. Last fall I set up a hose to take the water from the rain barrel to a reservoir closer to the gardening area and from there to a drip-line system that would water the plants. Because I had set this up at the end of the season I haven’t had a chance to try it out.
Since this plan, I have learned that the grey water should not sit for long periods of time because bad bacteria will form and you really don’t want to add that to the gardens. Also, Rick pointed out that the holes in the drip-lines might get clogged with soap residue. The best option is to add sand to the grey-water barrel for a filtration process
And so—my plan:
1. collect and use rain water, when it is available, in a rain barrel and the reservoir system.
2. store the grey water in an additional rain barrel and let it drain every two or three days, whenever the barrel gets full, allowing the plants to get a good drink.
3. add the rocks and sand filtration system to the grey water barrel to purify the water and to prevent clogging the lines.
Thoughts, ideas, devil’s advocate questions are much appreciated. I have four months to figure this out.
