Water pumpjack

Water Pumpjack on Your Factorio Server

Water Pumpjack by daahl solves a classic siting problem: instead of anchoring your factory next to a lake or river, this pumpjack lets you extract water from essentially anywhere in the ground, albeit at a low rate. For multiplayer bases that outgrow their starting location and expand far from natural water, that's a welcome bit of flexibility.

Installing it on your rented server follows the usual routine: drop the zip into the mods/ folder and enable it via mod-list.json. Because your server automatically delivers mods to every client on join, all your teammates can use the Water Pumpjack right away without hunting down the file themselves.

Tip: Given the low extraction rate, treat it as a supplement for remote outposts rather than a replacement for regular water pumps.

Plan the rollout and operation

Water Pumpjack solves remote outpost bottlenecks but should not automatically replace ordinary shore pumps. Compare construction cost, energy use, and output with the intended role, and cap deployment if water logistics should remain a challenge. Test one remote outpost at full load and inspect fluid networks after a restart. Before removal, reroute dependant pipes and recipes to another water source.

For rollout, copy the save, mod-list.json, mod-settings.dat, and current mods directory. Enable the new zip on a server copy first and let Factorio validate dependencies and version ranges during boot. Connect at least two clients, use the core feature, save under a new name, and load that save again. Watch the server log, UPS, and synchronization in a realistic factory rather than only on an empty map. For updates, record the game, mod, and dependency versions together and change one package per test run. Content or recipe mods can leave saved entities and production chains behind, so do not remove them directly from the live world. On a copy, replace recipes, filters, and buildings before deleting the file. The original save then remains a reliable rollback. Also document the tested mod order so teammates and later maintenance windows always begin from the same reproducible combination.
