🚰 Emergency Drinking Water Point: Filtration, Chlorination, Boiling and Tank Distribution Lab

A 3D emergency water point fed by a tank truck: sand or ceramic filtration with Darcy head loss and clogging, chlorination with Chick-Watson kill and CT in a baffled contact tank, a boiling-energy balance, and tank draw-down with a tap queue. The experiment finds the contact time required at each chlorine dose and checks it against the closed-form solution.
