Rural households often have to rely on decentralised systems for their wastewater treatment and sanitation needs. The following image gives an overview of a recommended integrated decentralised wastewater treatment system for a rural household. The system is based on the concept of ecological sanitation, involving separation of brown, grey and yellow water through source control schemes. It focuses on the extraction of nutrients from brown and yellow water. The reuse of greywater for non-potable purposes is also integrated in order to help to close nutrient and water cycles.
