Organic slurry basin storage cover and method of fabricating and deploying cover

A cover system for installation to cover an organic slurry basin bordered by an elongate berm along a first side thereof, comprising:

• a cover fabricated of a plurality of cover sections of geotextile fabric laid out along a first side of an organic slurry basin in fanfold relationship parallel to the berm and next to the lagoon with adjacent edges of the panels interconnected on site at the basin, the cover having a leading edge on the last of said sections for moving across the basin in deployment of the cover over the lagoon;
• a floatation device connected to the leading edge of the cover in order to pull the cover over the surface of organic slurry material located in the basin upon deployment of the cover;
• a plurality of deployment lines connected at one end to the leading edge and extendable across the lagoon basin to the side opposite the berm;
• a mandrel assembly for temporary installation along a second side of the basin opposite the first side so that the deployment lines can be wound around the mandrel to pull the cover across the basin;
• and
• tether lines secured to edges of the cover for connecting the cover to anchors installed along the perimeter of the lagoon basin.

A method of covering an organic waste storage lagoon basin containing a quantity of organic waste and having an elongate berm along a first side of the basin, comprising:

• providing a plurality of panels of geotextile fabric in sufficient number to span the width of the basin to be covered;
• successively laying out along the first edge of the basin parallel to the berm said panels of geotextile fabric in fanfold fashion;
• overlapping edges of adjacent panels as they are laid out and fastening the adjacent panel edges together;
• attaching a flotation device to the last edge of the top panel and attaching deployment lines to the flotation device;
• extending the deployment lines to the opposite side of the basin;
• providing a mandrel on the opposite side of the basin and winding the deployment lines on the mandrel to pull the cover across the basin as the flotation device floats on the surface of the organic waste located in the basin;
• using tether lines to tether the cover in place at a plurality of tether points such that the cover floats atop the lagoon basin to substantially cover the lagoon basin.

A method of covering an organic waste storage lagoon basin containing a quantity of organic waste and having an elongate berm along a first side of the basin, comprising:

• providing a plurality of panels of interconnected multiple strata material including a top sacrificial layer of material, a foam layer and a geotextile fabric layer, said panels in sufficient number to span the width of the basin to be covered;
• successively laying out along the first edge of the basin parallel to the berm said panels of geotextile fabric in fanfold fashion in a manner such that the sacrificial layer will remain on top when the cover is deployed over the basin;
• overlapping edges of adjacent panels as they are laid out and fastening the adjacent panel edges together;
• attaching a flotation device to the last edge of the top panel and attaching deployment lines to the flotation device;
• extending the deployment lines to the opposite side of the basin;
• providing a mandrel on the opposite side of the basin and winding the deployment lines on the mandrel to pull the cover across the basin as the flotation device floats on the surface of the organic waste located in the basin;
• using tether lines to tether the cover in place at a plurality of tether points such that the cover floats atop the lagoon basin to substantially cover the lagoon basin.
