Temporary sanitary waste removal system and method useful for application to construction sites

Abstract

A temporary system design and method for evacuating sanitary waste via gravity during vertical building construction can be extended vertically to connect more than one tankless gravity flush toilet in series. This system can provide for gravity sanitary waste removal during building construction.

I claim: 
     
         1 . A temporary sanitary waste removal system, comprising:
 a tankless gravity flush toilet including a toilet drain;   a water supply riser with a water lateral in fluid connection with both the water supply riser and the gravity flush toilet; and   a sanitary riser stack with a waste lateral in fluid connection at an inlet end with the toilet drain and at an outlet end with the sanitary riser stack.   
     
     
         2 . The system of  claim 1 , wherein the water supply riser comprises a plurality of riser segments in fluid connection. 
     
     
         3 . The system of  claim 1 , wherein the sanitary riser stack comprises a plurality of riser segments in fluid connection. 
     
     
         4 . The system of  claim 1 , comprising first and second tankless gravity flush toilets connected, in series, to a same water supply riser by respective first and second water laterals, and to a same sanitary riser stack by respective first and second waste laterals. 
     
     
         5 . The system of  claim 4 , wherein a in elevation distance between a connection of the first waste lateral to the sanitary riser stack and a connection of the second waste lateral to the sanitary riser stack is in a range of about 4 feet to about 100 feet. 
     
     
         6 . The system of  claim 4 , comprising a third tankless gravity flush toilet connected, in series, to the same sanitary riser stack. 
     
     
         7 . The system of  claim 1 , wherein the tankless gravity flush toilet is without an internal P-trap. 
     
     
         8 . A method of providing for sanitary waste removal, the method comprising:
 obtaining a tankless gravity flush toilet including a toilet drain;   providing a water supply riser and connecting the gravity flush toilet to the water supply riser via a water lateral in fluid connection with both the water supply riser and the gravity flush toilet;   providing a sanitary riser stack and connecting the gravity flush toilet to the sanitary riser stack via a waste lateral in fluid connection at an inlet end with the toilet drain and at an outlet end with the sanitary riser stack; and   connecting a lower end of the sanitary riser stack to a sewer system or a waste collection container.   
     
     
         9 . A method of providing for sanitary waste removal, the method comprising:
 providing a temporary sanitary waste removal system according to  claim 1  at a building construction site;   extending the water supply riser to a higher elevation by attaching a water riser extension segment to a top end of the water supply riser;   extending the sanitary waste riser stack to a higher elevation by attaching a waste riser stack extension segment to a top end of the waste riser stack;   connecting a second tankless gravity flush toilet to the sanitary waste riser via a second waste lateral in fluid connection at an inlet end with a toilet drain of the second tankless gravity flush toilet and at an outlet end with the waste riser stack extension segment; and   connecting the second tankless gravity flush toilet to the water supply riser via a second water lateral in fluid connection with both the second tankless gravity flush toilet and the water riser extension segment.   
     
     
         10 . The method of  claim 9 , further comprising:
 connecting a third tankless gravity flush toilet to the sanitary waste riser via a third waste lateral in fluid connection at an inlet end with a toilet drain of the third tankless gravity flush toilet and at an outlet end with the waste riser stack extension segment; and   connecting the third tankless gravity flush toilet to the water supply riser via a third water lateral in fluid connection with both the third tankless gravity flush toilet and the water riser extension segment.   
     
     
         11 . The method of  claim 9 , further comprising disassembling the temporary sanitary waste removal system and removing it from the building construction site.
