The Problem: Clean water is often unavailable in developing countries, the wilderness, or in areas that have been impacted by natural disasters. In order to remove contaminants in drinking water, water pumps are created. However, not all human powered water filtration pumps are durable or safe to use.
The Solution: Is to design and build a durable, safe to use, human-powered water filtration pump that gives the user the ability to pump and filter water from many sources, including those that are hard to reach or hazardous.
Criteria/Constraints:
-
The pump must be completely human-powered, the power of pumping must be done without any external help or machine.
-
Should be capable of being operated by one person. For the final demonstration, only one person may operate the pump.
-
The pump may be made of any materials.
-
The design may use 3D printed parts where possible.
-
The pump must provide water at a flow rate of at least 4 liters per minute with the user exerting a moderate effort of approximately 30 to 45 pump strokes per minute.
-
Pump can filter 5 gallons (approximately 19 liters) of water in less than 5 minutes.
-
The pump must filter the water and send the output through a hose that will fit on or into the mouth of a clear plastic 2-liter bottle.
-
The pump must be able to draw water from a source at least 10 feet away and 5 feet below the pump--the design and prototype must include any hoses or other devices to meet this requirement, and it must include a screen or filter that blocks sediment and debris from entering the pump.
-
The pump must be easily portable, so it must be able to be folded or disassembled and carried in a pouch that is no more than 2 feet long and 6 inches in diameter and weigh no more than 20 pounds (including all parts and the pouch).
-
The pump must be able to use an off the shelf microfilter that will be provided to the team by Skills21. Teams may use one or two microfilters in their design.
