Graywater recycling system including rainwater recovery

Abstract

A graywater recycling system having separate graywater and blackwater drain lines and a graywater flushing line connected to an upstream end of the blackwater drain line. The system is also provided with a subsurface graywater irrigation network with a graywater flushing line connected to the network. A rainwater collection system is in fluid communication with a graywater collection and distribution network. The system may be provided with a fire protection system in fluid communication with the graywater network and the rainwater system. Additionally, the separate graywater and blackwater piping may be run in a trench separator having a divider and closure lids.

1 . A graywater recycling system comprising:
 separate graywater and blackwater drain lines; and   a graywater flushing line connected to an upstream end of said blackwater drain line.   
   
   
       2 . A graywater recycling system comprising:
 a subsurface graywater irrigation network; and   a graywater flushing line connected to said network.   
   
   
       3 . The graywater recycling system of  claim 1  further comprising:
 a rainwater collection system in fluid communication with a graywater collection and distribution network.   
   
   
       4 . The graywater recycling system of  claim 1  further comprising:
 a graywater collection and distribution network; and   a flushing water source provided by said graywater network.   
   
   
       5 . The recycling system of  claim 4  wherein said flushing water source is further in fluid communication with a rainwater collection and distribution network. 
   
   
       6 . The graywater recycling system of  claim 3  further comprising a fire protection sprinkler system in fluid communication with the graywater collection and distribution network.
