MAPPING OF POTABLE WATER DISTRIBUTION NETWORK AND IDENTIFICATION OF PRIORITY AREAS FOR EXTENSION IN YAOUNDE - CAMEROON

Abstract

Rational and equitable distribution of potable water is one of the major challenges of our time.
Numerous programmes and projects aimed at ensuring access to Potable water have been
initiated in Cameroon in general and Yaounde in particular but the much-desired outcome of
“access to all” is more of a theoretical than a practical reality. It is based on this premise that this
paper provides a useful lens/windowon the current state of the water distribution network in the
city of Yaounde through the use of the Geographical Information Systems (GIS) with a view to
provide a wealth of information that will enable decision-makers to have a strategic vision on the
priority areas for extension of the Potable water network in the city of Yaounde. The
methodology consisted of combining a set of tools and approaches such as GIS, multi-criteria
analysis, grey data from population density, housing density, alternative water sources and the
current water distribution network. The findings have revealed a mismatch/uneven distribution of
the water network within the various neighbourhoods under study with a consequent imbalance
between supply and demand. Such neighbourhoods with limited pipe borne water, the findings of
this paper suggest are, priority areas for extension of the water distribution network in Yaounde.
In these neighbourhoods, the populations have implemented coping strategies through the setting
up of alternative water sources for their water supplies, which regrettably has a negative impact
on health.
