Sustainable Water Treatment Process

In nature, wetland and floodplain plants function to clean water, while supporting a variety of species including fish, birds, mammals, amphibians, insects and aquatic invertebrates and microbes. Wetlands can be managed or created with ecological and engineering knowledge to treat harmful flows of contaminated water, producing usable water in the process and supporting ecological services. Wetlands Work! designs ecologically engineered water treatment processes to transform domestic sewage and other waste streams into improved water. We use common wetland plant species to provide an active root surface area, which kick-starts a food-chain that breaks down the waste into food usable by other numerous organisms in the system.

Wetlands Work! designs can be applied in communities in need of sustainable, low cost access to improved water. The water produced from constructed wetlands is usually non-potable but keeps the local environment healthy, and can be treated further to meet WHO drinking water standards. Our flexible models have vast potential especially in off-the-grid rural areas where open space, wind and sunlight are available. A simple system can be set up in several days, cheaply and with locally available materials, using gravity flow – or, if necessary, wind or solar pumping power — and has minimal maintenance needs. Similar principles are used to design systems for other types of wastewater, including certain types of industrial effluents.
