Stone Water Well (ZarSasha's Fork)
A continuation of the beautiful mod Stone Water Well created by bSun0000 and presented by steinio on the Mod Portal, on the basis of the updated fork by TheDogOfChaos. It has been ported to Factorio 2.1 and improved upon in many small ways, according to my preference (see changelog).
Features: The mod adds the stone well, which has a 5x5 footprint and pumps water directly from the underground. Pumping rate can be configured, and there are options for making the well require electricity or making it available earlier. Sensible surface restrictions apply in Space Age, but planets can still be whitelisted.
Balancing: By default, the well produces water at a maximum rate of 1200 units/s, similar to the offshore pump. It can be unlocked through a separate tech right after green science, but can also be set to unlock earlier, with steam power. To provide some semblance of balance and realism, the well costs a decent amount of stone to craft. If set to require electricity, it will be prioritized on the power network. In Space Age, the well is entirely restricted from being built in space, and can normally only be built on Nauvis and Gleba, which contain liquid water on their surfaces. Even if allowed in the settings to be built there, the heating requirement on frozen planets like Aquilo is very high (2.52MW by default) and scales directly with pumping capacity.
Compatibility: When Pyanodons Coal Processing is installed, the tech can be researched much earlier and at a much lower cost. With AAI Industry installed and early unlock enabled, the well becomes available with basic fluid handling (this also affects Space Exploration). In Space Age, the planets Lignumis, Pelagos, Panglia, Foliax and Virentis from their respective mods are whitelisted by default.
Licensing: The mod is released under a simple MIT-license, but gives credit to the original mod while indicating any changes, as required by its CC BY 3.0 license. The mod uses some of the original graphics and simple derivatives thereof, while the code and in-game text have been extensively modified (see attribution file within the mod folder itself).
