Greywater Recycling Loop (2D Schematic)

Shower, sink and laundry water — greywater — makes up more than half of a typical household's indoor water use, and most of it is clean enough to reuse for toilet flushing or irrigation after simple filtration and disinfection. This 2D schematic runs the same live daily mass balance as the 3D version: set the number of occupants, the filter train's efficiency and the storage tank's capacity, toggle which reuse points are open, and watch treated water animate along the pipes from sources through the filter into the tank and back out to reuse, with a real turbidity model, a scrolling strip chart, and a running freshwater-savings figure.
