Abstract: An apparatus for the solar distillation of contaminated water which includes a substantially airtight enclosure having an evaporation chamber and condensation chamber. The evaporation chamber has a lower reservoir and an upper inclined surface which is transparent to solar radiation. The condensation chamber includes a thermally conductive condensation wall and a collecting reservoir for collecting the condensed water. A thermal insulative partition is located intermediate the evaporation chamber and the condensation chamber, and includes an upper port and a lower port. At least one thermally conductive conduit may be located within the condensation chamber and externally vented at the upper and lower portions thereof.
