Water in Sandustry

How to get Water

Four sources. Move through them as the factory grows instead of hunting a new puddle every time.

How to use Lumlings for Water

Capture Lumlings, keep them in a contained pen above their own Water, and let the output fall into a reservoir. Lumlings sitting in Water produce poorly or stop.

How many Lumlings can you find?

Lumling count is world-dependent rather than a fixed number you should design around. Players have reported substantially different totals between worlds, so build your factory around observed supply rather than assuming a universal creature count.

There is no useful universal “you need exactly X Lumlings” rule. First check whether your Lumlings are actually above the Water level and producing freely before deciding you simply need more.

Is infinite Water possible?

Treat Lumlings and steam-to-rain recovery as renewable Water systems. Do not rely on a guaranteed “1 Water becomes 2 Water” duplication ratio, because observed rain returns can be affected by how Water is removed and returned by the world.

How to move Water around your factory

Gravity is enough nearby and downhill. Once Pipes unlock, Pump → Pipe → Liquid Vent is the factory route.

How to move Water upward

Use a Pump → Pipe → Liquid Vent network. Pipes are independent of gravity and can run through terrain, so you do not need to convert Water into Steam just to move it upward once fluid logistics are unlocked.

How Pumps, Pipes and Liquid Vents work

A Pump pulls liquid into a Pipe. A Liquid Vent releases it. Pipes can pass through terrain and blocks. Lava cannot go through Pipes.

This is a capacity reference, not a calculator. Immersion, mixed liquids, submerged Vents and actual demand all change the real result.

Clear the unwanted liquid from the outlet, keep Water on its own Pipe network, and do not let a Steam Vent sit in a Water basin.

How to distribute Water between factory systems

One reservoir can feed Gold, Flowers and Steam. There is no single best priority — send Water to the line that is starving.

Why did my Water disappear?

Water that never settles into a depression evaporates after about 45 seconds and enters the rain buffer. It is not automatically a bug, and it may return later as rain.

Check diagonal corners before blaming evaporation.

1. 01

   Did it leak through a corner?

2. 02

   Was it flowing across a flat or open surface?

3. 03

   Did it react with another material?

4. 04

   Was it consumed by production?

5. 05

   Did it enter a Pipe / Vent network?

Water system not working?

Name the break — source, transport, output, or consumption — then run the matching check.

Water, Steam and Rain

This is the mechanic reference. It is not the first thing a factory needs to solve.

Useful Water layouts

Three readable starting patterns. None of these is a “best infinite setup.”
