This study presents a literature review of the quality of Grey water generated in different, especially developing, countries, constituents found in Grey water, some treatment systems, and natural materials for treatment, some reuse strategies and public perception regarding grey water reuse. The review shows that generation rates are mostly influenced by lifestyle, types of fixtures used and climatic conditions. Contaminants found in grey water are largely associated with the type of detergent used and influenced by other household practices. Many of the treatment systems reviewed were unable to provide total treatment as each system has its unique strength in removing a group of targeted pollutants. The review revealed that some naturally occurring materials such as Moringa oleifera and sawdust can be used to remove targeted pollutants in grey water. The study further showed that user perceptions towards grey water treatment and reuse were only favourable towards non-potable purposes, mostly due to perceived contamination or lack of trust in the level of treatment offered by the treatment system. It was then allowed to down flow through the vertical column from the top at the flow rate of 0.5 ml/min. The treated outlet collected at the interval of 7 days from the outlet Nozzle provided at the bottom of the column and their characteristics were analysed and compared with the initial.
