Abstract: A gray water reclamation system is disclosed. The system includes a gray water filter and a gray water conduit for receiving exclusively gray water from at least one household source and passively delivering the gray water through a water filter to remove impurities therefrom. Filtered water is temporarily stored in an underground tank. A sensing apparatus such as a pressure tank determines when gray water is required by an outside irrigation system, inside toilets or other appliances. Suitable controls direct a pump to transmit water from the storage tank to either irrigation apparatus or, after further filtering, to appliances in need of water.

Abstract: A waste water disposal system for a building which saves and recycles the grey waste water for lawn and plant irrigation. The system includes interconnected waste water pipes containing two separate passageways, one for reusable grey water and the other for sewer water, and three different types of T-fittings used with the two passageway waste water pipes, each T-fitting designed to interconnect two axially aligned waste water pipes and having an offset opening to one of the waste water passageways in the fitting, one type of T-fitting designed to discharge sewer water into the sewer water passageway in the fitting, the second type designed to discharge grey water into the grey water passageway of the fitting, and the third type designed to vent to the atmosphere both passageways in the fitting.
