Water drives the Wet Sand loop and several later reactions. Its level, spill path, and destination matter as much as its quantity, so treat every pool as part of the factory.
Working route
Surface lakes, underground layers, Ice, Steam rain, and Lumling are documented sources. In early game without nearby lakes, melt Cryogun Snow or Snowmaker pellets inside a heated 3x3 collection box.
Water levels out across a plane and can leak through corner-to-corner block joins. Close the gap with an additional block.
Water turns Sand into Wet Sand and Wet Seed into its wet state. It also turns to Steam when it meets Fire.
Direct industrial mining Laser fire at environmental Ice blocks to rapidly liquefy them into flowing Water on-site, bypassing long piping trenches.
The official Wiki documents a Cryoblaster-to-Snow-to-Steam-to-rain route. Route the rain back into a collection pool.
Questions answered
Use the Cryogun Snow Melting trick: spray Snow with your Cryoblaster into a 3x3 enclosed container and hit it with a torch, Flamethrower, or direct heat block. It melts instantly into pure liquid Water.
Yes. As of Update #3, sustained Laser fire melts Ice blocks directly into Water, creating a mobile water source in cold biomes.
Diagonal corner-to-corner block gaps permit liquid penetration due to pixel physics. Place a block on the diagonal intersection to form a sealed 90-degree seal.
