In this study, a basin type solar still is investigated whose enclosure walls are soaked with a periodic injection. The equipment was tested under the climatic conditions in Semnan, Iran. Two enclosures were manufactured for this purpose. One of them enjoyed a pump to soak the enclosure walls, while the other one was a conventional system with no such pump. In active chamber, effects of pump's working and off durations were investigated before being compared with those of a passive one. The results showed that the efficiency could be enhanced 7% and the rate of output fresh water could be increased ∼75% with the wet walls. © 2016 American Institute of Chemical Engineers Environ Prog, 36: 532–538, 2017
