Community Water Supply

With this human-powered strainer system, flood water is changed to safe drinking water. When users step onto foot pedals continuously, water flows through a pipe into filters until it is purified. Providing one water supply per one community helps reduce water delivery problems due to heavy weight and leaking packages. Buoys attached to the platform allow another boat to move the water supply to a flooding area easily. In a normal condition, a community can use this water supply by placing it near a water source.

Suggestions for further development

  1. Some structure parts may be reduced in size or eliminated, and the missing tasks be included in the main structure such as the handle. This is to reduce the overall weight and facilitate the move to increase the acquired amount of clean water. A larger water filter may be developed, or a larger pump may be used to increase the water pressure.

  2. The distance of the tank may be adjusted and the filter be lowered to reduce the water pressure. A one-sided pedal may be designed, while the other side can be used as a water pump to speed up the water flow. Further studies are required to optimize the efficiency of the entire system.

  3. The main problem of water filtration in the community is the people's participation in water production and the assurance of quality of the drinking water. Therefore, the following factors must be considered:
    3.1 The parts must be easy to clean and appear clean at all times and allow for a closed water flow system which means the water goes in and out from the same side without any foreign particles entering the system. A lid to cover the details of the machinery may be produced.
    3.2 There should be a communication system to notify the level at which the water is being filtered, especially when the process is finished in order to assure the consumers of the completion.

  4. The design of the drinking water dispenser should attract children in the community to come and play instead of work. Unlike adults, these children have more free time in the event of flooding.
