Contain first, route short, mix nearby
Follow official Water behavior: let it settle in a basin, close corner leaks, and keep the Sand contact point near the source.
Layout concept: keep Water in a small basin, route it a short distance, and make Wet Sand close enough that every failure is visible.

Water should settle before you depend on it.
Close corner gaps around reservoirs before blaming supply.
Move the conversion point near the source so Wet Sand production is visible.
Contain Water first, keep the route short, and place the Sand contact zone close enough that leaks and loss stay visible before they spread into a factory-wide shortage.
Pump count, pipe length, and the best long-term loop still depend on terrain, elevation, and how much Water the rest of the factory needs. Use this as a readable early pattern, not a universal benchmark.
The safest early answer is not a long transport line. It is a short contained route from a basin into nearby Sand so you can see whether Water is leaking, evaporating into Steam, or simply missing the mixing point.
Early Water becomes hard to trust when it travels too far over flat ground, leaks through diagonal corners, or hits heat and becomes a Steam problem. That is why the route stays short and visible.
