The Water Mill is an IC2 Generator that produces EU, by either having a Water Bucket placed in its lower slot, or being placed in a body of water. When placed in a body of water it must be underwater, and connected with wires to an EU Storage Device/IC2 Machine in order for it to transmit power. 

It is commonly used during the start of the game, and for low-voltage operations. They are the second cheapest type of Generator, which makes them a great low-cost power-source.

Place either Water Cells or Water Buckets in the lower slot or place the Water Mill inside water. Then either place an RE Battery in the upper slot or connect the Water Mill to an EU storage device with a cable. The Water Mill will charge the battery or output power at a rate of 1 EU/t (manned) or 0.01 EU/t per block of adjacent water (unmanned). The maximum output of an unmanned Water Mill is 0.25EU/t (3x3x3 cube of running water with the mill in the middle, plus 1 piece of cable to direct the energy = 25 water tiles).

Since their maximum output is 1EU/t, they work well with Tin Cables, which are cheap, have low energy losses and can tolerate up to 5 EU/t. Water Mills are a simple way to generate a small amount of EU, and are recommended for starting players due to their low cost. However, Water Mills will only become a viable power source in large numbers. They are not commonly used in the endgame.

A Water Mill can hold up to four buckets worth of water, with a fifth full bucket in its lower slot. One bucket will power a Water Mill for about 25 seconds, generating 1,000 EU.

Water Mills may also be used along with a Tank and an Iron Waterproof Pipe to craft Water Strainers.
