Drain (GregTech 6)

The Drain is a machine cover added by GregTech 6 that collects fluids from the world and fills them into tanks or pipes.

If there is a fluid block adjacent to the Drain, it will be removed and the installed tank or pipe will be filled with 1000L of that fluid. However, if GregTech's rules for infinite water would allow that fluid block to reappear, the tank or pipe will be filled with 16,000L of that fluid every 20 ticks. GregTech's infinite water rules allow Sea Water to be collected in Ocean or Beach biomes, Dirty Water to be collected in Swamp biomes, and allows plain Water to be collected in River or Lake biomes if the Drain is installed at height levels where Water normally appears. The Drain also functions in Twilight Forest River biomes.

If there is no fluid block adjacent, and it is currently raining, the Drain will collect up to 100L of Water every 100 ticks. The amount collected depends on the amount of rainfall in the local biome, and is doubled during a thunderstorm.
