Abstract
A method for covering a lagoon, manure storage basin, waste water retention pond, water reservoir, open top material storage tank, stacks or piles of commodities, having a perimeter and a containment portion, wherein the method acquires the placement of a perforated tubular member about the perimeter, laying a resilient cover on the containment portion such that an edge of the cover is covering the tubular member and is sealed at the edge. A pumping device attached to the tabular member for extracting air through the tubular member with the pumping device which forces the cover downwardly by the use of negative air pressure.
Claims6
A method for covering a lagoon manure storage basin, waste water retention pond, water reservoir, open top material storage tank, or stacks or piles having a perimeter and a containment portion, the method comprises;
- placing a perforated tubular member about the perimeter of a lagoon, manure storage basin, waste water retention pond, water reservoir, open top material storage tank, or stacks or piles of commodities;
- laying a resilient cover on the containment portion lagoon, manure storage basin, waste water retention pond, water reservoir, open top material storage tank, or stacks or piles of commodities, such that the perimeter of the cover is covering the tubular member;
- sealing the perimeter of the cover with a small amount of ballasted weight;
- providing a pumping device;
- attaching the pumping device to the tubular member;
- and extracting air through the tubular member with the pumping device which forces the cover downward by the use of negative air pressure.
A lagoon, manure storage basin, waste water retention pond, water reservoir, open top material storage tank, or stacks or piles of commodities cover comprising:
- a resilient lagoon, manure storage basin, waste water retention pond, water reservoir, open top material storage tank, or stacks or piles of commodities covering sheet;
- a perforated tubular member for location beneath the covering sheet;
- sealing of the perimeter of the covering sheet by use of a small amount of ballasted weight;
- and a pumping device arranged such that, in use, air from beneath the covering sheet is oxtracted through the perforated hose to create negative air pressure which holds the covering sheet in position over a lagoon, manure storage basin, waste water retention pond, water reservoir, open top material storage tank, or stacks or piles of commodities.
