An apparatus for covering a water container and treating a source water therein, the water container having an open top, the apparatus comprising:

• one or more longitudinally extending dividing walls mountable to an interior space of the water container for partitioning the interior space of the water container into a plurality of water-treatment zones, each dividing wall comprises one or more first openings for fluid communication between adjacent water-treatment zones thereabout;
• and
• a cover mountable to at least a portion of the open top of the water container above the one or more dividing walls, the cover comprising one or more vaulted cover sections for defining one or more gas chambers above the dividing walls;
• wherein each cover section comprises:
• a condensation surface in the corresponding gas chamber for condensing a steam evaporated from the source water in the water container to clean water, and
• at least one water-collection channel coupled to at least one side of the condensation surface for collecting the clean water condensed therefrom.
