Sandustry Infinite Water & Rain Guide: Steam Cloud Cycle, Condensation & Leak-Proof Basins.

Water in Sandustry is not just a mined fluid—it is part of a dynamic atmospheric hydrological cycle. Learn how to convert infinite Snow via Cryoblaster into Steam, vent it to the open sky to trigger regional rainfall, and engineer catch basins that prevent diagonal seam leaks.

Quick answer

How to trigger rain and generate infinite water

Shoot infinite Snow with a Cryoblaster, ignite or melt the Snow into Steam, and channel the rising Steam through a vertical chute into the open sky. Once the sky saturates with Steam, it triggers regional rainfall. Collect the downpour in a wide U-shaped basin sealed against diagonal pixel clipping.

01

Start with the slow renewable source

The official route begins with a Cryoblaster producing Snow indefinitely. This is a slow source, so treat it as a long-term supply rather than an instant replacement for an existing Water pool.

02

Give Steam an open route to the sky

Turn Snow into Steam where it can rise to the open sky. The rain step depends on that vertical route; a sealed roof or blocked chamber turns a renewable plan into a missing-output problem.

03

Build a low, contained rain pool

Catch the returning rain in a walled depression with a clear Pump connection. In my test, a boiler and catch area made the intended route visible before it was connected to later demand; the image is a personal layout reference, not a universal footprint.

04

Prevent loss before increasing production

The official Water notes say unsettled droplets evaporate after 45 seconds. Seal diagonal corner leaks, give droplets a low settling surface, and only then consider adding more source capacity.

05

Connect the renewable pool like any other Water source

Once the pool settles, use a Pump, continuous Pipe trunk, and Liquid Vent for delivery. Keep the renewable source separate from other fluids so an output problem is easy to localize.

Questions answered

blockage.

How does rain work in Sandustry?

When Steam rises and exits into the unobstructed open sky, the physics engine registers cloud condensation. Once density thresholds are met, rain falls over the surface area.

Can you create infinite water in Sandustry?

Yes. Generate infinite Snow using a Cryoblaster, melt it into Steam, vent it to the sky, and collect the resulting rain in a sealed surface basin.

Why does my water disappear in Sandustry?

Water that fails to settle into a 2+ block deep pool within 45 seconds evaporates into thin air. Furthermore, single-block diagonal corners have micro-gaps that drain fluids.

How do I fix leaking water pools?

Reinforce all diagonal corner joints with a secondary solid block behind the seam to eliminate sub-pixel fluid clipping.

How to condense water (как конденсировать воду)?

Channel Steam into a Condenser building or release it into the atmosphere to condense naturally into falling rain.

Source Wiki

  • The Cryoblaster tool generates Snow indefinitely, providing the foundation for infinite renewable water.
  • Steam that escapes into the open sky condenses into atmospheric rain clouds and precipitates back down.
  • Water droplets spread until level; uncontained droplets on dry terrain evaporate permanently after 45 seconds.
  • Pipes connect submerged Pumps directly to Liquid Vents across unlimited distances.

Community-tested

  • My v0.4.12 test uses a boiler and contained catch area as a visual troubleshooting reference. It does not establish a universal collection footprint or water rate.
