Pax Silica is a US-led supply chain initiative with 24 signatories. The Philippines joined it in April 2026, and its first industrial hub — roughly 1,620 hectares at New Clark City, Tarlac — is being negotiated now, with the framework agreement reported as due around November. This is not a study of something that might happen one day. It is a study of a decision with a date on it.
No build-out has been announced. The load, the water source, the waste handling and the horizon in this simulator are set by the reader, not taken from any proponent, and nothing here describes or predicts the intentions of any government, agency or company.
Water, grid, hazard and waste designed together, before commissioning, in the open. A region that has been offered heavy industry for a generation gets a way of saying yes that survives a dry season and a typhoon in the same year. The standard becomes the export, and the next site does not start the argument again.
A withdrawal sized against an average year. A grid contingency that arrives in the same week as the weather. Effluent deferred to a later phase that keeps moving. None of these fail loudly on their own. They fail together, slowly, and the cost is paid by a basin, a grid and a set of towns that were never in the room when the decision was taken.
Which of the two you get is not decided at the ribbon-cutting. It is decided in the order the four systems are designed, in the months before the agreement is signed, and it is reversible for a while and then it is not. The simulator exists so that a planner, a council, a journalist or a student can watch that window close, with the sources in reach, while it is still open. It is free, and it is public.
Free and public. Create an account and move the order the four systems are designed in, with the sources in reach.
Water, grid, hazard and waste assessed as one picture — the floor your judgement is built on, not the ceiling.
