Sandustry Renewable Water: Sources, Steam and Limits

Separate external inputs from recycled Water

Snow and Ice can be useful water sources, but their origin matters. Melting a finite Ice deposit spends stored material. A Snowmaker consumes Water to produce Snow, so feeding its output back into the water line does not by itself create a new source. Identify which input enters from outside the loop.

The official Water page mentions a Cryoblaster-to-Snow route, while the Steam page explains why apparent rain duplication can reclaim previously lost Water. These describe different effects. This guide therefore uses renewable supply as a planning question, not a promise of literally infinite output from an isolated closed loop.

Give Steam an open route and rain a collection basin

Heat Water or Snow to obtain Steam, then provide a path without a sealing ceiling. Steam rises and pools beneath roofs; reaching the sky allows it to condense and fall as rain. Put a collection basin beneath the intended return area instead of assuming every drop lands in your existing reservoir.

Keep the Steam riser separate from the consumer inlet. A roof added during later factory expansion can stop a previously open path. If steam accumulates below a ledge, fix that obstruction before increasing heat. Use the Water transport guide to move collected liquid back to storage.

Check whether the reserve actually grows

Record the starting reservoir, external Snow or Ice used, Water sent to Sand or Seed, and the ending reservoir. Compare equal observation intervals. An initial increase does not establish an unlimited source: the Steam page describes an internal rain buffer that can return Water lost through lateral movement.

First measure with consumption paused; then repeat with the intended consumer active. If storage falls only in the second run, supply does not cover demand. If it falls in both, inspect collection and transport losses. These are suggested measurements for your setup, not results from a test performed by this website.

Troubleshooting

• The loop produces Steam but no stored Water

  Confirm the vapor reaches the sky, then widen and seal the rain basin so condensed drops do not miss or leak from it.

• Water production cannot keep up with the factory

  Separate collection from consumers, measure net rain, and increase Snow or capture capacity rather than assuming the loop is lossless.
