Using the existing septic tanks, the wastewater from Dormitory 1, which houses 120 schoolgirls, is fed into a siphon shaft and from there evenly distributed to five container-based compact constructed wetland systems at intervals.
These are artificially aerated vertical flow filter systems with marsh plants, which are supplied with oxygen from below by solar-powered aerators. The capacity of the plant is designed for a wastewater volume of 7 m³ per day. The treated wastewater is fed to a vegetated leachfield (bananas, papayas, etc.). The entire plant works without a pump by gravity flow mode.
