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.

Abstract: This invention relates to a gray water recycling invention that utilizes filtered gray water for maintaining constant moisture levels in building foundations and for other irrigation uses. The invention allows for the mixture of pesticides with a gray water stream injected under a building in order to treat for insects. Additionally, pesticides, fungicides, or fertilizers can be injected into a gray water stream prior to its application in landscape irrigating. The invention has applications in both a single residence and fill development real estate setting.
