The objective of this project was to design a water purification system that can be constructed from easily available materials, common to the particular country, and is capable of the complete water purification process. The designed system consisted of a treadle pump (built from wood or bamboo) to pull the water from its source, a filter (made of readily available materials such as sand) to remove contaminants and improve palatability of water, an electrolysis system to allow chlorination from salt water (using locally sourced salt), and a car battery (which could be sourced from a scrapped car) that could be charged by pedaling a mountain bike connected to a DC motor (which could be obtained from a scrapped scooter). In addition, a set of instructions was developed that can be interpreted with minimal text. In Phase I, a working model and the schematics of the system were developed and tested. In Phase II, the schematics will be taken to a developing nation, India, and a water purification system will be built and evaluated on site. The schematics will be modified according to the ability of locals to understand and construct the system and schematics will be developed for other developing nations with different material resources. Depending on the success of the project, additional funding will be requested to distribute these instructions to as many developing nations as possible.
