Drinking water is a necessity to which millions of people throughout the world have limited access. Water is often seen as the most basic and accessible element of life, and seemingly the most plentiful. More than a billion people lack access to drinking Water. Simply providing access to clean Water could save two million lives each year. As the population grows, the freshwater available to each resident dwindles. Water purification is the removal of contaminants from untreated water to produce drinking water that is pure enough for human consumption. Substances that are removed during the process include parasites, bacteria, algae, viruses, fungi, minerals (including toxic metals such as lead, copper and arsenic), and man-made chemical pollutants. In this paper, an apparatus and methods for producing purified drinking water are disclosed. A hand pump is used in a closed system to generate pressure to pass the water through a series of filters and a reverse osmosis membrane to obtain potable water at the outlet. The flow obtained was analysed using ANSYS and the system delivering highest output was chosen. The project facilitates the availability of pure drinking water without using any electrical components or devices. It is a cheap and efficient means to produce drinking water.
