Drinkable water is a basic necessity for humanity, and the increase in human population growth has led to water pollution to the surface and underground water reservoirs. In order to meet the increasing demand for potable water, researchers have developed various technologies to meet this target. Solar distillation is a technology suitable for producing distilled water from brackish water. This is achieved by the use of a solar still. A solar still is a simple solar device used in converting salt/brackish water into potable water. In this research, the productivity of water by a double slope solar still was determined by varying the water depth and surrounding temperature for nine days in the premises of Lagos State University, Ojo, Nigeria at 6.5oN, 3.35oE. In this research embarked upon, it was observed that at a depth of 2.0cm the maximum output of the solar still was obtained and a maximum efficiency of 25.3%.
