A constructed wetland system was built for a 7-person household. The system was designed to treat greywater from bathroom, laundry and kitchen. The greywater is collected in a 500-litre, two-chambered settling tank. A subsequent dosing tank of 200 litres with a mechanical siphon discharges greywater onto a vertical- ow planted lter 3–4 times a day through a perforated pipe (Ø 50 mm) xed above the surface level of the bed. The lter material of the bed (6 m2) is composed of a 20-cm layer of gravel (20–40 mm) at the bottom, 10 cm of ne gravel (10 mm) in the middle and 60 cm of coarse sand on the top.
