The hand washing station was aimed to be placed on road sides and outside homeless shelters.

Concept Sketches

Selected Concept

This Concept was selected as it looked like a soap dispenser which would make it easier for people to understand and recognize its intended use.

It houses two 55 gallon tanks which provide 400+ wash cycles. The electronics for the hand washing cycle was programmed in such a way that there would be an initial flow of water for 10 seconds and then pause for 20 seconds to allow the user to thoroughly scrub their hands with soap without wasting water after which the flow would resume again for another 30 seconds to allow proper rinse off.

1:1 working Prototype

A 1:1 working prototype was fabricated using wood, metal and plastic to test out the electronics and ease of use as well as to estimate fabrication cost.
