Abstract
In Dakar, there has been a considerable deficit in the drinking water supply for more than a decade. The distribution is poorly controlled in this region. And yet, there is no lack of supply sources or solutions. With a drinking water deficit of 300,000 m3/d to fill, the State of Senegal proposed two (02) options: firstly, the construction of a second Plan at Keur Momar Sarr on the Guiers Lake with a capacity of 75,000 m3/d coupled with a third pipeline between Keur Momar Sarr and Thies (KMS3); secondly, the construction of a seawater desalination Plant with a capacity of 75,000 m3/d. In this article, we studied the evolution of the drinking water consumption and the statistical data relating to population growth, which is the key element in the drinking water consumption evolution in Dakar. We were able to extract the equations from the trend curves that made it possible to predict a population growth. The results obtained with the equations and the curves show that the real needs for drinking water in Dakar are proportional to population growth.

Summary
A country of West Africa, is divided into fourteen (14) regions. It is located in the intertropical zone and is bordered on the north by Mauritania, on the south by Guinea Bissau and the Republic of Guinea; to the East by Mali and to the West by the Atlantic Ocean. The capital, Dakar concentrates a bulk of economic, political and administrative activities, and is facing an exponential demographic growth [1]. Dakar is characterized by a high human density. 23.2% of the Senegalese population live on 0.3% of the national territory. The drinking water supply system in Dakar has been facing increasing needs [3]
