WaterAid | Using reeds to treat wastewater

Without sewerage, waste water from communities pollutes open areas and water sources.

At Sunga in Thimmee, WaterAid's partner ENPHO are trialling reed beds to treat wastewater. Following its success other schemes are being planned across Kathmandu.

After four days in sedimentation tanks, wastewater from 110 households flows into the reed beds where it is naturally filtered and cleaned. The resulting water is then stored, and will be diverted to a neighbouring school to be used in their toilet block. The sludge in the sedimentation tanks is left to decompose before being used by farmers as fertiliser.
