<p>A wastewater disposal system for a building which recycles grey wastewater for irrigation. The system has interconnected wastewater pipes (20-29) containing two separate passageways (20a, 20b), one for reusable grey water and the other for sewer water, and three different types of T-fittings (30, 40, 50, 60) are used with the two passageway wastewater pipes (20-29), each T-fitting (30, 40, 50, 60) designed to interconnect two axially aligned wastewater pipes and having an offset opening to one of the wastewater passageways in the fitting, one type of T-fitting (30) designed to discharge sewer water into the sewer water passageway in the fitting, the second type (40) designed to discharge grey water into the grey water passageway (20a) of the fitting, and the third type (50, 60) designed to vent to atmosphere both passageways (20a, 20b) in the fitting. A fourth T-fitting (70) is designed to divert reusable grey water into a storage tank and channel sewer water into a sewer system.</p> |
