Hygiene, Public Health and Diseases

Health issues are often closely related to hygiene practices and the management of water and sanitation.

1. Introduction

Hand Washing…

…blocks of the transmission of diseases.

… is not common everywhere.

… is cheap & simple.

… has the potential to significantly

improve your local water and

sanitation system

… doesn’t easily become a part of people’s daily routines.

Hand Washing Can Block the Transmission Route

• Hand washing can considerably contribute to an improved and sustainable sanitation system by interrupting the transmission of disease agents.

Consequently, diarrhoea, respiratory infections as well as skin infections and trachoma are significantly reduced.

• Example: A study suggests that hand washing with soap, particularly after contact with faeces (post-defecation and after handling a child’s stool), can reduce diarrhoeal incidence by 42-47 percent.

The General Design Principle

SIMPLE, EFFECTIVE, SUSTAINABLE

Design Concerns

Technical considerations:•Convenient location of facilities (i.e. close to work place,

community centre, toilet facilities, etc.)•Convenient installation (e.g. height suit both children

and adults)•Clean area / comfort (e.g. drainage, frequent cleaning)•Properly working devices (e.g. frequent maintenance)

BUT: That’s not good enough!

Need for making users understand of the purpose and benefits of hand washing (awareness raising)

in order to make the consequent use of hand-washing facilities an integral part of people’s daily

routines.



Example 1: Simple Hand Washing Container

One of the simplest ways of making a hand sink is to find a container (e.g. a can or plastic bottle) and drill a hole in the bottom. After filled with water, hands can be washed while the water is slowly trickling down. This low-cost option is applied easily and very effectively.

Example 2: The ‘Tippy Tap’ Hand Sink

A tippy tap style hand sink can be made by several ways: The most common way is to find a container (i.e. a large can, bottle or pot) and drill a hole near the top. A string and a pedal is attached at the top of the container allowing the water to flow out (by means of hands of feet)

Example 3: The ‘Tap Up’ Hand Sink

A bucket with a valve at the bottom can also serve as a hand sink. Moving the valve upwards make the water flow out.
