A working simulation

Pumps, filters, boilers, dosing and the controls that run them are modelled as working machines, not scenery. They have state and controls: gauges read real values, switches switch, lamps light. You can inspect them, operate them, work out what is wrong and put it right.

  1. Explore the plant rooms, corridors and control rooms behind the pools.
  2. Diagnose the problem from the instruments, the alarms and what you can see.
  3. Repair it, often in the room where it happened.
A plant room: two blue pump motors, white filter vessels and pipework labelled feed and discharge.
The Lounge pool's plant room: pumps, filters and their valves.
A museum hall: a plate heat exchanger, a pump and a red temperature display reading 27.0, with explanatory signs.
A museum hall explains each machine, and every one of them works.
A dead rat held up under a banner reading: You got a DEAD RAT!
Not everything in a skimmer basket is pleasant.

Updates

An occasional email when there is something new to play: new rooms, new machinery and new things to go wrong.
