 Ideally,
every home in the world would have an adequate, safe
supply of drinking water piped directly to their home.
However, 1.1 billion people currently lack access to
an improved water supply, and many more gather water
from improved sources and then store it unsafely in
their homes. The Safe Water System was designed to provide
safe drinking water for populations who, currently,
can only obtain their water from the following sources:
|
| |
|
Surface water sources such as rivers or lakes |
| |
|
Groundwater wells that are potentially contaminated,
particularly open shallow wells |
| |
|
Piped systems in which the water is inadequately treated
or flow is intermittent, allowing contamination through
leaks where pipes are connected |
| |
|
Piped water systems in which intermittent flow requires
households to store water |
| |
|
Water tankers |
| |
|
Water vendors whose source of water is
not safe or whose tanker or storage tank is not likely
to be clean |
| |
| Other potential target populations
are in areas where water collection containers are not
cleaned before filling them with water or wide-mouth
containers are used to collect and store water. Disinfection
of the source water may not always be necessary in these
cases (e.g., if the source water is safe) but the practice
of disinfection prevents recontamination of water in
the home and supports hygiene improvements in the home.
