摘要：Sustainable management of drinking water requires knowledge of the factors which affect the
household expenditure on the resource.
To attain this objective, a questionnaire was administered to some households in Yaounde and
linear regression techniques were used to determine the factors that can explain water expenditure.
The main determinants were found to be; the type of housing, the size of the household and the
income of the head of household.
Therefore, to avoid over-exploitation of water resources, high water bills, illnesses related to water
of poor quality, unavailability of water, it is imperative to sensitise the population on the need for the
sustainable management of natural resources in general, and water resources in particular, through
the mastery of the factors affecting the cost of water per household.
