Mekanism: Water Generator Rebuild
by MisoPy
Mekanism: Water Generator Rebuild, published under the MWGR abbreviation, is a Mekanism add-on that adds a water source block able to hold up to 2.1 billion water sources in one block.
What it does
The rebuild reworks an earlier atmospheric water generator for Mekanism, updated for the current Forge and NeoForge builds. Its large internal capacity lets a single block supply water far beyond what a standard source block provides, and the author notes that the value is a fixed maximum rather than an unlimited supply.
Installation needs Mekanism on the loader it targets. Servers that run it need every player to install it too. Forge files cover 1.12.2, 1.16.5, 1.18.2, 1.19.2, 1.20.1 and 1.21.1, with 1.1.9 for 1.20.1 as the latest Forge file and 1.1.1 for 1.21.1 as the latest NeoForge file. The code is released under the MIT License and is open source.
Key features
Large water capacity
A single water generator block holds up to 2.1 billion water sources, a quantity no ordinary source block reaches.
Atmospheric water source
The block works as an atmospheric water generator in the Mekanism style, producing water that can feed machines and pipes.
Mekanism integration
The block follows the mechanics of the Mekanism base mod, so players who already use its machines find the same setup.
Searchable keyword
Searching for water generator in a recipe or item viewer such as JEI finds the block quickly.

What the author says
This mod is essentially an improved version of MamaeMDL's Mekanism Atmospheric Water Generator. The aforementioned mod adds 2.1 billion water sources contained within a single block, but it is made with MCreator and is a mod that can cause compatibility issues.
