Water storage lid

Abstract

Tank lids include a first coated substrate including a first part having a first thickness, a first elastomer coating the first part, a second coated substrate positioned adjacent to the first coated substrate, the second coated substrate including a second part having a second thickness, and a second elastomer coating the second part. A first seam can be formed between the first and second coated substrates to allow for moisture to pass between the first and second coated substrates so that moisture is allowed to seep away from the top of the tank lid.

What is claimed is: 
     
         1 . A system, comprising:
 a tank comprising a lower wall and four side walls extending vertically from the lower wall and defining an interior space;   a lid disposed within the interior space, the lid comprising:
 a first coated substrate, comprising:
 a first substrate having a first thickness; 
 a first elastomer coating disposed on the first substrate; and 
 a first planar portion; 
 
 a second coated substrate in direct contact with the first coated substrate and positioned adjacent to the first coated substrate, the second coated substrate comprising:
 a second substrate having a second thickness; 
 a second elastomer coating disposed on the second substrate; and 
 a second planar portion; 
 
 wherein the first and second planar portions are coplanar when the second substrate is positioned adjacent to the first coated substrate and perpendicular to each of the respective first and second thicknesses of the first and second substrates; and 
 a seam formed between the first and second coated substrates. 
   
     
     
         2 . The system of  claim 1 , wherein each of the first coated substrate and the second coated substrate independently has a width of about 1 m to about 2 m and a length of about 3 mto about 10 m. 
     
     
         3 . The system of  claim 2 , wherein the first thickness and the second thickness are independently about 0.5 inch to about 12 inches. 
     
     
         4 . The system of  claim 1 , wherein each of the first coated substrate and the second coated substrate comprises a foam material. 
     
     
         5 . The system of  claim 4 , wherein the foam material of each of the first coated substrate and the second coated substrate independently has a density of about 1 lb/ft 3  to about 5 lb/ft 3 . 
     
     
         6 . The system of  claim 5 , wherein the density is about 1.5 lb/ft 3  to about 2.5 lb/ft 3 . 
     
     
         7 . The system of  claim 4 , wherein the foam material of each of the first coated substrate and the second coated substrate is independently selected from the group consisting of polystyrene, polyisocyanurate, polyurethane, polyvinyl chloride, polyimide, silicone, and combination(s) thereof. 
     
     
         8 . The system of  claim 1 , further comprising a strap connected to the first coated substrate at a first end of the strap and connected to the second coated substrate at a second end of the strap. 
     
     
         9 . The system of  claim 8 , wherein the strap is disposed substantially perpendicular relative to the seam. 
     
     
         10 . The system of  claim 8 , wherein the strap is disposed substantially diagonally offset relative to the seam. 
     
     
         11 . The system of  claim 8 , wherein the strap is fixably disposed between:
 the first elastomeric coating and the first substrate, and the second elastomeric coating and the second substrate.   
     
     
         12 . The system of  claim 1 , wherein the lid has a width of about 1 m to about 30 m and a length of about 1 m to about 30 m. 
     
     
         13 . The system of  claim 1 , wherein the lid contacts at least two of the four side walls within the interior space of the tank. 
     
     
         14 . The system of  claim 13 , wherein the lid contacts the four side walls within the interior space of the tank. 
     
     
         15 . The system of  claim 1 , wherein the first coated substrate is encapsulated by the first elastomer and the second coated substrate is encapsulated by the second elastomer. 
     
     
         16 . The system of  claim 1 , wherein each of the first coated substrate and the second coated substrate is shaped to interlock with each other to form the seam. 
     
     
         17 . The system of  claim 1 , wherein the first coated substrate has a first edge and the second coated substrate has a second edge, wherein the second edge interfits within the first edge to form the seam. 
     
     
         18 . The system of  claim 1 , wherein each of the first substrate and the second substrate comprises a polystyrene. 
     
     
         19 . The system of  claim 18 , wherein each of the first elastomer and the second elastomer comprises a polyurea. 
     
     
         20 . The floating lid of  claim 1 , wherein each of the first elastomer coating and the second elastomer coating independently has a thickness of at least about 50 mils.
