The supply of safe drinking water is a major worldwide problem. In the developed world the frequency of water related problems are increasing. The purpose of this study was to develop a water treatment unit, that could be used to treat water abstracted from domestic wells.The main focus of this work was on the removal dissolved iron by simple aeration and filtration followed by chemical free disinfection. The principle application for this unit is mainly for single house operation under the following parameters. That the treatment is carried out without the use of chemicals, it is simple to maintain, can be constructed from readily available components, inexpensive to build and operate. While the design of this unit concentrates on single dwelling application, it is possible that it could be expanded to treat the groundwater supply for small groups of dwellings.
