DECISION SUPPORT

Deploy this when

You can isolate the module, observe a full cycle and provide a deliberate overflow route before connecting the main supply.

Delay this when

The required material states, filters or safety shutoffs are still missing. A copied layout cannot replace its operating conditions.

The renewable source

Lumlings create water reliably when housed above the surface of the reservoir. If the tank rises around them, production appears to slow because they are submerged. Separate the creature pen from storage with a drip floor or narrow outlets.

Use enough horizontal room that droplets can find the outlet without pooling inside the pen. A transparent inspection gap makes it obvious whether the source or the tank is responsible for low flow.

Reservoir architecture

The storage tank needs four layers: sealed floor, working volume, overflow line and dry service space. Route overflow to secondary tanks or a safe drain; do not let it discover its own path through the factory.

Advanced Filters can create controlled liquid gates. Standard Filters pass water, so they should not be used as a tank wall unless passing water is the goal.

Steam recovery

Heating water creates Steam. Steam that reaches open sky contributes to a rain buffer and can later return as water. This makes a large factory less wasteful, but the delay prevents it from behaving like a precise pump loop.

Keep steam chimneys clear and separate from Wisp material paths. Rain should land in a broad capture roof that slopes into storage rather than onto electrical or burner modules.

Failure modes

  • Lumlings sitting in water are not equivalent to Lumlings dripping into water.
  • A reservoir without overflow eventually becomes a terrain-wide flood.
  • Diagonal corner leaks can empty a tank into the lowest factory layer.
  • Rain capture located above mixed-material belts introduces random wetting reactions.
