ABSTRACT:
A lagoon containing aqueous waste to be volume reduced is provided with a cover having one or more segments, each of which is mounted upon a frame and is movable from a covering position to a position adjacent the lagoon. During fair weather, the cover is positioned adjacent the lagoon and liquid waste is pumped from the lagoon and dispersed over the surface of the cover. When inclement weather approaches, the pumping of the waste is ceased, the surface of the cover cleaned by flushing with clean water, and the cover moved into position over the lagoon to prevent precipitation from diluting the waste liquid. The invention is particularly useful in areas of low net evaporation rate.
