Specifications: This family villa is situated in the North of Athens at the foot of Mount Penteli. A rootzone installation was chosen for the following reasons:

- No public sewage system
- Domestic water supply directly sourced from ground water
- No hydraulic conductivity in the soil to allow filtration (a requirement of conventional methods)
- No access to empty a conventional sewage tank

From the first operation year the efficiency of the system has shown excellent results.

N.B. A rootzone installation requires very little surface area (1/3 size of the tennis court as shown in the photo)
