Aqueous Accumulator

Aqueous accumulator

No, it does not work with lava. You monster.

An aqueous accumulator is a device that generates water by extracting it from the device’s surroundings.


A placed aqueous accumulator can be instantly picked up by dismantling it with a crescent hammer. Its configuration is preserved in the item. It can also be mined using a pickaxe.




When placed, an aqueous accumulator faces the player. It can face any of the four cardinal directions, and can be rotated using a crescent hammer or similar.


When placed between at least two water source blocks, an aqueous accumulator will start producing water. The rate at which water is produced depends on the amount of adjacent water sources.

Adjacent water sources Production rate
2 25 mB/t
3 50 mB/t
4 75 mB/t
5 100 mB/t
6 125 mB/t

Water is not actually produced every tick, but in batches every 40 ticks (2 seconds).

An aqueous accumulator will also produce water when it rains on top of it. In this case, water is produced at a rate of 25 mB/t.

If enabled, an aqueous accumulator will also produce water without adjacent water sources or rain. In this case, water is produced at a rate of 1 mB/t. This is disabled by default.

Aqueous accumulators do not work in the Nether.


Water can exit an aqueous accumulator through its sides. Every side of an aqueous accumulator may be configured to be able to output water.

An aqueous accumulator can automatically transfer water out of any configured output sides. This is called auto-output, and occurs every 40 ticks (2 seconds), before more water is produced. Up to 2000 mB of water can be transferred at a time.

Which sides can output water and whether auto-output is enabled can be configured using the Configuration tab in the device’s GUI.

Redstone control

An aqueous accumulator may be configured to respond to redstone signals. It can be in one of three modes:

Redstone control is disabled. The aqueous accumulator works whenever possible. This is the default mode.
The aqueous accumulator works when not powered. When powered, it stops working.
The aqueous accumulator only works when powered.

The current mode can be set using the Redstone Control tab in the device’s GUI.


An aqueous accumulator can have a signalum security lock installed to restrict who can access it.


An aqueous accumulator’s configuration can be saved on a redprint to be copied to other aqueous accumulators.
