This project was proposed by an international NGO which offers assistance to craftspeople in the developing world. The project looks at improving the design of ceramic water filters, and has several lines of investigation:

• Obtaining a very small pore size in ceramic water filters by designing a method to create small, but regular, sized burn out material for the firing process. This would aid the removal of dirt and microbes in the water and could potentially have significant impacts on the health of the community.
• Look at the current method of pressing the filters to determine the loading on the mould which creates uneven stresses in the clay and hence an uneven distribution of pore sizes.
• Improving the flow of the filter by using a hand vacuum pump
