Direct Answer
Find Water in surface lakes or underground deposits, or obtain it by melting Ice, letting Steam reach the sky and fall as rain, or using Lumlings. One Sand plus one Water makes two Wet Sand, while one Seed plus one Water makes one Wet Seed. The official Wiki also describes a sustainable Water cycle using Steam, rain, and Cryoblaster-created Snow.
Where Water comes from
Water is a liquid Material and a critical factory resource. The verified sources are surface lakes, underground water deposits, melting Ice, rain formed when Steam reaches the sky, and Lumlings. These sources support both early Gold production and later automated systems.
Creator guidance recommends scouting for a large lake before choosing the first factory site. Early progression uses substantial Water together with Sand, so a small pocket can be less convenient than a large reservoir. The exact amount required for a particular base is To be confirmed because layouts and production goals differ.
Wet Sand and Wet Seed recipes
The official material gives a direct reaction: one Sand plus one Water produces two Wet Sand. Wet Sand can later be processed into Gold and Residue, connecting Water to Research progression. This is why losing a water supply can slow the early factory.
A second verified reaction is one Seed plus one Water producing one Wet Seed. A Wet Seed placed on a Planter Box grows into a Flower, which can later provide Amethelis and Gold. Water therefore links the Sand-based and seed-based production branches.
Move underground Water to the surface
Heating Water turns it into Steam, and Steam rises. If the Steam reaches the sky, it condenses and falls back as Water. The official sources describe this cycle as a way to move underground Water toward the surface.
Pumps act as fluid inputs, Liquid Vents act as outputs, and Pipes connect them. Pumping continues when fluid is at or above the Pump and the destination level remains below the Liquid Vent's level. A single line can carry multiple fluids, but the vent prioritizes the closest liquid, so separate lines are safer.
Blocks, leaks, and evaporation
Water pools in depressions and settles into a flat surface. Loose droplets that fail to settle for about 45 seconds evaporate, which can explain apparent loss during a poorly contained transfer. Water may also leak through diagonal corner gaps.
Block, Conveyor Belt, Kinetic Press, and Flux Emanator are listed as Water-blocking structures. Water can pass through most other building blocks, so visual enclosure alone may not make a tank watertight. Test the boundary with the specific structures named by the official Wiki rather than assuming every building blocks liquid.
Sustainable and infinite Water
The official Wiki describes a method that combines Steam and rain with Snow created by a Cryoblaster to produce an infinite Water cycle. That confirms the underlying sustainable-loop concept. The authority for the concept is stronger than any single creator layout or claimed dimension.
A creator example uses directed flow, tanks, belts, heating, freezing, and melting to automate the loop. It mentions walls 40 tiles high, but the collected authority summary does not establish that measurement as a universal minimum for every design. Treat exact dimensions, tank ratios, and throughput as To be confirmed unless reproduced in the current version.
Troubleshoot a Water system
If Water disappears, first check for unsettled droplets, diagonal leaks, and building materials that do not block liquid. If a pipeline behaves unpredictably, check whether more than one fluid is sharing it and whether the Liquid Vent is prioritizing a nearer liquid. If a Pump stops, compare the source and destination fluid levels with the verified pumping conditions.
For a Steam route, confirm that the gas has an open path upward and can reach the sky before expecting rain. For a Wet Seed or Wet Sand line, confirm that Water physically reaches the Seed or Sand. Exact reaction timing and ideal automation ratios are To be confirmed in the supplied material.
How Sandustry materials behave
Every pixel in Sandustry can have its own physical properties, and resources may be solid, liquid, gas, Wisp, terrain, or non-physical currency. Heat can move a solid toward liquid or a liquid toward gas, while cold structures reverse those state changes. Individual resource pages must still follow their specific burnable, meltable, wettable, density, and tool rules.
The Material Scanner upgrade helps reveal how a resource can be refined or used in another process. Creator evidence shows why this matters: fire can affect Slag while not affecting Spores, and different hard materials need different digging tools. Exact interactions not named by the supplied sources remain To be confirmed.
Transport depends on matter type
Conveyor Belts and Launchers are the primary verified tools for moving many solid resources. Filters separate mixed solid piles with Allow and Block rules, while Advanced Filters later extend that behavior to solid, liquid, and gas resources. Amethelis is also launchable and can be moved in large piles with an Aerokinetic Fan.
Pumps, Pipes, and Liquid Vents move fluids other than lava. A shared pipeline can carry multiple fluids, but the vent cannot filter them and prioritizes the closest liquid. Water may also pass through many building blocks, making material-specific containment part of logistics design.
Resources connect progression systems
Water and Sand produce Wet Sand, which can later yield Gold and Residue. Water and Seed produce Wet Seed, which grows into a Flower and supplies Amethelis plus Gold. Amethelis then supports the Dry Amethelis, Florin, Florinol, Battery, and Energy chain.
Fluxite serves Upgrades and later becomes producible from Voidbloom through a Flux Emanator. Artifacts follow a different route because they are exploration and progression finds rather than ordinary Materials. Aura is also distinct because it is a non-physical late-game currency created through Auralite Crystals and nanobots.
How uncertain values are handled
The supplied research confirms selected recipes, outputs, costs, drop heights, densities, and tool restrictions. It does not provide every timing, throughput, map coordinate, spawn chance, or optimal machine ratio. Missing values are marked To be confirmed rather than estimated from visual footage.
Official Wiki information takes priority over older Demo discussions when the two differ. Creator layouts remain useful for showing possible automation patterns, but their dimensions and labels are not automatically universal. This lets each resource page integrate multiple sources without blending verified facts with assumptions.
Use this guide with the current Early Access build
Sandustry entered Early Access on August 13, 2026 and continues to receive official updates. The current official Wiki is the primary gameplay reference when it differs from an older Demo discussion, while Steam and Xbox listings are the primary platform references. A creator video can demonstrate a working layout, but it does not automatically establish a universal value or current-version rule.
Check the page's verified sources when an update changes a recipe, cost, tool restriction, platform feature, or interface path. This guide preserves confirmed numbers only where the supplied research names them and labels unresolved details To be confirmed. That approach keeps the answer usable for search while preventing an unsupported count, character name, redeem code, command, or production ratio from becoming false guidance.

This page filters and consolidates the supplied research. Any detail not established by those sources is marked To be confirmed.
