       8 . The adjustable collar of  claim 1 , wherein said water impermeable disk-like plate comprises a multi-piece construction and fastening means for reversibly fastening said multiple pieces together, thereby firmly fastening an inner peripheral surface of said opening to an outer peripheral surface of said casing, pipe, pole or post.  
   
   
       9 . The adjustable collar of  claim 8 , wherein said fastening means is selected from the group consisting of screws, pins, bolts and nuts or wing-nuts, fastening components that hook, snap, or comprise interlocking parts, snug-fitting male/female pieces, adhesives, clips, and bands.  
   
   
       10 . The adjustable collar of  claim 9 , comprising one or more series of marks or perforations defining at least one removable conduit segment for receiving therethrough a wiring conduit of said well, said removable conduit segment or segments being disposed adjacent to or in abutment with one or more of said removable annular segments.  
   
   
       11 . The adjustable collar of  claim 9 , further comprising one or more series of marks or perforations defining one or more removable post segments for receiving therethrough one or more pipes, poles and/or posts, said removable post segment or segments being concentric and/or eccentric with respect to said central opening.  
   
   
       12 . The adjustable collar of  claim 11 , wherein said removable post segment or segments comprise at least one shape selected from the group consisting or circular, semi-circular, rectangular and square.  
   
   
       13 . The adjustable collar of  claim 9 , wherein said removable annular segments are perforated or scored to break along predefined seams.  
   
   
       14 . The adjustable collar of  claim 9 , further comprising sealing means between said adjustable collar and said upper terminus of said casing, pipe, pole or post.  
   
   
       15 . The adjustable collar of  claim 14 , wherein said sealing means comprises a weather-resistant gasket or adhesive sealant.  
   
   
       16 . The adjustable collar of  claim 3 , wherein said removable annular segments and/or said removable post segments, when removed, allow said collar to accommodate standard sized wellhead casings, pipes, poles or posts selected from the group consisting of 4″ by 4″ square, 5″ external diameter, 5.563″ external diameter, 6.625″ external diameter, 8.625″ external diameter, 10.75″ external diameter.  
   
   
       17 . The adjustable collar of  claim 16 , further comprising one or more series of marks or perforations eccentric with respect to said central opening and defining at least one removable conduit segment for receiving therethrough a wiring conduit of said well, said removable conduit segment or segments being disposed adjacent to or in abutment with one or more of said removable annular segments.  
   
   
       18 . The adjustable collar of  claim 9 , wherein said removable annular segments and/or said removable post segments, when removed, allow said collar to accommodate standard sized wellhead casings, pipes, poles or posts selected from the group consisting of 4″ by 4″ square, 5″ external diameter, 5.563″ external diameter, 6.625″ external diameter, 8.625″ external diameter, 10.75″ external diameter.
