greywater system 3d model

a dual plumbing system under a kitchen sink that harvests grey water from dirty non recycled water, its connected to the bottom of a kitchen sink with a flap covering 2 plumbing systems, 1 plumbing system takes the grey water to the tank outside connected to the irrigation for plants and 1 plumbing system takes the non recyclable water to the sewage, the flap is controlled by a person that's either washing fruit or veggies with no soap/chemicals or doing the dishes using chemicals that's not recycled, the person controls the flow of water by sliding the flap to 1 of the 2 plumbing systems: this mimics the epiglottis closing windpipe or the food pipe in the human body
