Combining wastewater treatment with water recycling and biomass production has been shown to be a viable alternative to traditional wastewater treatment systems in peri-urban areas. Research in Niamey, Niger, indicates that the introduction of plant species such as duckweed to stabilisation ponds provides improved water quality as well as additional income generation through the harvesting of biomass for animal feed.
