Many developing countries may not reach targets of providing access to safe water sources and sanitation services for all by 2030. Access to these services is a fundamental requirement for the well-being of individuals and the development of nations. A little over half of Mozambique´s population has access to safe water sources. In contrast, access to sanitation services has not kept pace with the progress made in water access. In this article, based on data from the General State Account of Mozambique, which includes the description of annual investment made by the Government and using the results of the Household Budget Surveys, it is shown that if the average percentage values of public investment of 2009 to 2021 be the same in the following years in the water and sanitation sector it will not reach the goals of sustainable objective number 6 in 2030.
