Method and apparatus for waste evacuation

Abstract

A method and apparatus for waste evacuation using an extendible and retractable hose for transferring the waste have been described.

1 . An apparatus comprising: 
 an indicator for a black water tank, said indicator capable of indicating a level in said black water tank;    an indicator for a gray water tank, said indicator capable of indicating a level in said gray water tank;    an indicator for a first valve, said indicator capable of indicating a open and a closed state for said first valve, said first valve in communication with said black water tank;    an indicator for a second valve, said indicator capable of indicating a open and a closed state for said second valve, said second valve in communication with said gray water tank;    an indicator for a hose, said indicator capable of indicating a extended and a retraced state for said hose said hose in communication with said first valve and said second valve;    a control for opening and closing said first valve, said control in communication with said first valve;    a control for opening and closing said second valve, said control in communication with said second valve; and    a control for extending and retracting said hose, said control in communication with an extend/retract module, said extend/retract module in gas communication with said hose.    
     
     
         2 . The apparatus of  claim 1  further comprising a panel having mounted thereon said black water tank indicator, said gray water tank indicator, said first valve indicator, said second valve indicator, and said hose indicator.  
     
     
         3 . The apparatus of  claim 2  further comprising said panel having mounted thereon said first valve control, said second valve control, and said hose controls.  
     
     
         4 . A method comprising: 
 controlling a black water tank valve;    controlling a gray water tank valve;    controlling an extendible/retractable hose wherein said extendible/retractable hose is in fluid communication with said black water tank valve and said gray water tank valve.    
     
     
         5 . The method of  claim 4  wherein said controlling said black water tank valve further comprises opening and closing said black water tank valve.  
     
     
         6 . The method of  claim 5  wherein said controlling said gray water tank valve further comprises opening and closing said gray water tank valve.  
     
     
         7 . The method of  claim 6  wherein said controlling said extendible/retractable hose further comprises extending and retracting said extendible/retractable hose.  
     
     
         8 . The method of  claim 7  further comprising: 
 first extending said extendible/retractable hose;    second opening said black water tank valve;    third closing said black water tank valve;    fourth opening said gray water tank valve;    fifth closing said gray water tank valve;    sixth retracting said extendible/retractable hose;    
     
     
         9 . An apparatus comprising: 
 means for opening and closing a valve in communication with a black water tank;    means for opening and closing a valve in communication with a gray water tank;    means for extending and retracting a hose in communication with said black water tank valve and said gray water tank valve.    
     
     
         10 . The apparatus of  claim 10  wherein an extending and retracting end of said hose when fully retracted is located inside a box.
