Residential waste water disposal system

DETAILED DESCRIPTION The invention lies in the field of systems for the disposal of waste waters generated within a building and more particularly to a waste water disposal system which saves and recycles for further use a portion of the building's waste water, thus conserving a sizable portion of the water usually used in the operation and maintenance of the building.
Most buildings, whether residential or commercial, contain a number of appliances which require fresh water and generate waste water which has to be drained off and disposed of in an approved and sanitary manner.
Some appliances such as toilets and garbage disposals generate waste waters which must be drained off and disposed of in a public sewer or a septic system.
However, other appliances such as bathtubs, shower stalls, bathroom and kitchen sinks, and clothes washers generate waste waters commonly called grey water containing only small amounts of soap or detergent residues which can be safely reused to irrigate lawns and plants surrounding the building.
Recycling of the grey water generated in the building would save the use of considerable fresh water normally used in the irrigation of the building's lawns and plants.
I have invented a waste water disposal system which permits the recapture and storage for irrigation or other reuse of the grey waste water generated in a building.
My water conserving waste water disposal system in operation drains the waste waters from all the appliances in the building into one common disposal line, but that line contains two parallel but separate passageways, one for the reusable grey water destined to be stored for reuse and the other passageway for the contaminated sewer water to be emptied into a public sewer line or a septic system.
In order to drain the waste water classified as reusable grey water into the grey water passageway of the common disposal line and also to drain the contaminated sewer water into the other passageway, I have developed two unique T-fittings which permit the discharge of waste water from an appliance into the proper passageway without interference with the flow of previously discharged waste water through the two passageways in the common line
