Achieving hygiene through hand washing is an important intervention in interrupting the cycle of transmission of communicable diseases. A hand washing facility named “Press Tap” has been developed and was successfully tested in different user environments. The hand washing device - which is simple and low cost - works on a foot pressing mechanism and integrates the usage of soaps using the same mechanism. This paper presents the conceptual development of the Press Tap including the governing hydraulic equations of flow that form the theoretical basis for the design of the hand washing facility. The paper also gives the construction features of the different components as well as useful operation aspects that were realized during the pilot trials of the device in different user environments.
