Use the main Water guide for ordinary sources, containment, leaks, and flow. If Water exists but does not move, follow the Pump, Pipe, and Liquid Vent source-to-destination check instead of changing the renewable loop.

Build the officially documented renewable route

  1. Choose an external renewable input

    Use Lumlings or indefinitely generated Cryoblaster Snow; do not begin by recirculating the Water you want to measure.

  2. Keep Cryoblaster Snow visible

    Give Snow a separate chamber so its conversion is not hidden inside an existing reservoir.

  3. Create Steam with controlled heat

    The current official Steam page documents Steam from heated Water or Snow.

  4. Guide Steam to the sky

    Steam that reaches the sky returns as Water rain; the checked current page does not document an enclosed automatic timer.

  5. Capture Rain before connecting consumers

    Use a basin wide enough to make escaped return flow visible.

  6. Add consumer load last

    Start Wet Sand or Wet Seed production only after the unladen source is readable.

The documented Snow-to-Steam-to-rain route is separate from conflicting duplication and delayed-buffer reports.

Duplication claim, delayed rain buffer, and off-screen behavior

A duplication claim begins with an existing Water pool and says the loop returns more than it consumed. Current community explanations conflict: some players describe multiplication, others describe delayed rain returning from a simulation buffer, and one correction says the effect stops after reload or when the area is no longer being simulated. None of those reports establishes one universal multiplier or permanent layout.

Save and reload test

  1. Pause every consumer

    Wet Sand, Wet Seed, and other sinks must not hide whether the source itself changes.

  2. Mark the starting basin

    Use fixed geometry rather than moving droplets or a short visual impression.

  3. Wait for delayed Rain

    Do not count visible return until Steam and rain have completed the cycle.

  4. Move away and return

    Off-screen behavior is part of the current conflict and must not be assumed equivalent to active simulation.

  5. Save and reload

    Repeat the same observation after restart before classifying any net gain.

  6. Apply consumer load

    A stable source must still cover the real factory demand; visible temporary gain is not a supply rate.

Update record

  • 2026-08-23 — Added the direct Yes/No decision, stable-supply table, off-screen and reload checks, and removed the unsupported current enclosed-Steam timer.
  • 2026-08-22 — Restored the independent self-canonical page and separated renewable sources from duplication reports.

Frequently asked questions

Does Sandustry have renewable Water?

Yes. The official Water and Cryoblaster pages document Lumlings and indefinitely generated Snow that can become Steam and return as rain. They do not publish one stable factory output rate.

Is every apparent Water gain a duplication glitch?

No. Documented renewable inputs add supply, while a closed loop that begins with an existing pool may be returning delayed rain, behaving differently off-screen, or failing after reload. Classify the source before calling it duplication.

When is a Water loop stable enough for production?

Only after the source runs without consumers, completes delayed rain, survives save and reload, and still covers measured consumer load. A temporarily higher visible level is not the same as stable net supply.
