     DETAILED DESCRIPTION OF THE INVENTION 
     Referring to the drawings in detail wherein like elements are indicated by like numerals, there is shown a water on demand bag  1 . The bag  1  has a front  2 , rear  3 , top  4 , bottom  5 , two opposite sides  6 , an exterior surface  7 , and an interior  8  defined by said bag front, rear, top, bottom and sides. The bag sides  6  are formed into gussets for bag expansion. The bag bottom  5  may be formed into a general “V” shape to allowing maximum access to the bag contents. 
     The bag top  4  has a reinforced aperture  9  formed therein, through which a drinking tube  10  is inserted and extending into the bag interior  8  along the front  2  or rear  3  near to the bag bottom  5 . The drinking tube  10  is comprised of an elongated body  13  with two open ends, one end  11  positioned within the bag interior  8  and the other end  12  protruding external from the bag interior. The drink tube body portion  14  within the bag interior  8  may be fused centrally along the bag front  2  or rear  3 . 
     The bag front  2  has two handle straps  20  attached to the bag exterior surface  7  and folded one along the other. Each handle strap has two ends, one end  21  attached to the bag front  2  near to a side  6  and the other end  22  releasably attached to the opposite handle strap. Each strap fee end  22  has an adjacent adhesive area  23  covered by a removable paper tab  24 . 
     The bag top has a tear-down notch  30  formed therein, said notch  30  adapted to being torn open for full access to the contents of the bag interior  8 . This permits the bag contents to be poured onto a wound or other area needing cleaning, or into a container. See  FIG. 9 . 
     The drinking tube external end  12  may terminate in a bite and drink feature  16 . The drinking tube  10  may also have a cap  15  attached to its body  13  and removably inserted into the drinking tube exterior end  12 . See  FIGS. 11 and 13 . 
     As may be seen most clearly in  FIGS. 1 and 12 , the bag  1  is adapted to being attached about the torso  40  of a user, said bag attached by means of the handle straps  20  and joined together by means of the adhesive patches  23 . The drinking tube exterior end  12  extends to the user&#39;s mouth (not shown) providing access to the bag contents. 
     A purification capsule  50  may be attached to one of the interior walls of the water bag, either directly or inserted into a mesh patch  51  attached to one of the water bag interior walls. The capsule  50  is adapted to interact with water. Once the water bag  1  is filled with water, the capsule decontaminates the water. See  FIG. 14 . 
     The water bag bottom  5  may have an aperture  17  sealable by means of an adhesive strip  18 . This is intended to be a one-time sealable aperture. The end user would have the means for opening the water bag bottom, filling the bag with water, and then sealing the bottom. 
     It is understood that the above-described embodiment is merely illustrative of the application. Other embodiments may be readily devised by those skilled in the art which will embody the principles of the invention and fall within the spirit and scope thereof.
