Water issues: Future proofing the garden (part II)

greywater settling system

The above diagram shows the settling tank we now have. Grey water from the house must now pass through it before being released into the wetland area next to the pond.

The wetland area itself is at a level slightly higher than the pond allowing water to pass through the wetland area (and the network of plant roots) before reaching the pond.

The settling tank is made with two pieces of large water pipe that are used to create two columns of sand and gravel. This should help take out the worst of the contaminants from the water and is relatively easy to take apart and clean. Below you can see the tank and pipes which were used.

Any questions on the system or advice on how to improve it, please feel welcome to contact me.


About ifd66

From UK and living in Japan. I am very interested in sustainable development and in general ecology and conservation issues and solutions. Finished building a low impact family house in Shiga, Japan in 2013 and am now focused on using permaculture to develop our plot of land into a more sustainable, productive, and attractive space. My hope is that this blog is useful to those interested in similar issues and way of life.
